- * @ngdoc directive
- * @name ngApp
- * @module ng
- *
- * @element ANY
- * @param {angular.Module} ngApp an optional application
- * {@link angular.module module} name to load.
- * @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be
- * created in "strict-di" mode. This means that the application will fail to invoke functions which
- * do not use explicit function annotation (and are thus unsuitable for minification), as described
- * in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in
- * tracking down the root of these bugs.
- *
- * @description
- *
- * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
- * designates the **root element** of the application and is typically placed near the root element
- * of the page - e.g. on the `` or `` tags.
- *
- * There are a few things to keep in mind when using `ngApp`:
- * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
- * found in the document will be used to define the root element to auto-bootstrap as an
- * application. To run multiple applications in an HTML document you must manually bootstrap them using
- * {@link angular.bootstrap} instead.
- * - AngularJS applications cannot be nested within each other.
- * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
- * This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
- * {@link ngRoute.ngView `ngView`}.
- * Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
- * causing animations to stop working and making the injector inaccessible from outside the app.
- *
- * You can specify an **AngularJS module** to be used as the root module for the application. This
- * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
- * should contain the application code needed or have dependencies on other modules that will

+ *
+ * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
+ * designates the **root element** of the application and is typically placed near the root element
+ * of the page - e.g. on the `` or `` tags.
+ *
+ * There are a few things to keep in mind when using `ngApp`:
+ * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
+ * found in the document will be used to define the root element to auto-bootstrap as an
+ * application. To run multiple applications in an HTML document you must manually bootstrap them using
+ * {@link angular.bootstrap} instead.
+ * - AngularJS applications cannot be nested within each other.
+ * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
+ * This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
+ * {@link ngRoute.ngView `ngView`}.
+ * Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
+ * causing animations to stop working and making the injector inaccessible from outside the app.
+ *
+ * You can specify an **AngularJS module** to be used as the root module for the application. This
+ * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
+ * should contain the application code needed or have dependencies on other modules that will
+ * contain the code. See {@link angular.module} for more information.
+ *
+ * In the example below if the `ngApp` directive were not placed on the `html` element then the
+ * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
+ * would not be resolved to `3`.

-/**
- * @ngdoc function
- * @name angular.element
- * @module ng
- * @kind function
- *
- * @description
- * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
- *
- * If jQuery is available, `angular.element` is an alias for the
- * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
- * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
- *
- * jqLite is a tiny, API-compatible subset of jQuery that allows
- * Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
- * commonly needed functionality with the goal of having a very small footprint.
- *
- * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
- * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
- * specific version of jQuery if multiple versions exist on the page.
- *
- * **Note:** All element references in Angular are always wrapped with jQuery or
- * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.
- *
- * **Note:** Keep in mind that this function will not find elements
- * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
- * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.
- *
- * ## Angular's jqLite
- * jqLite provides only the following jQuery methods:
- *
- * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
- * - [`after()`](http://api.jquery.com/after/)
- * - [`append()`](http://api.jquery.com/append/)
- * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
- * - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData
- * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
- * - [`clone()`](http://api.jquery.com/clone/)
- * - [`contents()`](http://api.jquery.com/contents/)
- * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
- * As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
- * - [`data()`](http://api.jquery.com/data/)
- * - [`detach()`](http://api.jquery.com/detach/)
- * - [`empty()`](http://api.jquery.com/empty/)
- * - [`eq()`](http://api.jquery.com/eq/)
- * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
- * - [`hasClass()`](http://api.jquery.com/hasClass/)
- * - [`html()`](http://api.jquery.com/html/)
- * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
- * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
- * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
- * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
- * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
- * - [`prepend()`](http://api.jquery.com/prepend/)
- * - [`prop()`](http://api.jquery.com/prop/)
- * - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)
- * - [`remove()`](http://api.jquery.com/remove/)
- * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes
- * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
- * - [`removeData()`](http://api.jquery.com/removeData/)
- * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
- * - [`text()`](http://api.jquery.com/text/)
- * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
- * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers
- * - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter
- * - [`val()`](http://api.jquery.com/val/)
- * - [`wrap()`](http://api.jquery.com/wrap/)
- *
- * ## jQuery/jqLite Extras
- * Angular also provides the following additional methods and events to both jQuery and jqLite:
- *
- * ### Events
- * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
- * on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM
- * element before it is removed.
- *
- * ### Methods
- * - `controller(name)` - retrieves the controller of the current element or its parent. By default
- * retrieves controller associated with the `ngController` directive. If `name` is provided as
- * camelCase directive name, then the controller for this directive will be retrieved (e.g.
- * `'ngModel'`).
- * - `injector()` - retrieves the injector of the current element or its parent.
- * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
- * element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
- * be enabled.
- * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
- * current element. This getter should be used only on elements that contain a directive which starts a new isolate
- * scope. Calling `scope()` on this element always returns the original non-isolate scope.
- * Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
- * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
- * parent element is reached.
- *
- * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See
- * https://github.com/angular/angular.js/issues/14251 for more information.
- *
- * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
- * @returns {Object} jQuery object.

+ * @ngdoc function
+ * @name angular.element
+ * @module ng
+ * @kind function
+ *
+ * @description
+ * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
+ *
+ * If jQuery is available, `angular.element` is an alias for the
+ * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
+ * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
+ *
+ * jqLite is a tiny, API-compatible subset of jQuery that allows
+ * Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
+ * commonly needed functionality with the goal of having a very small footprint.
+ *
+ * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
+ * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
+ * specific version of jQuery if multiple versions exist on the page.
+ *
+ * **Note:** All element references in Angular are always wrapped with jQuery or
+ * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.
+ *
+ * **Note:** Keep in mind that this function will not find elements
+ * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
+ * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.
+ *
+ * ## Angular's jqLite
+ * jqLite provides only the following jQuery methods:
+ *
+ * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
+ * - [`after()`](http://api.jquery.com/after/)
+ * - [`append()`](http://api.jquery.com/append/)
+ * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
+ * - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData
+ * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
+ * - [`clone()`](http://api.jquery.com/clone/)
+ * - [`contents()`](http://api.jquery.com/contents/)
+ * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
+ * As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
+ * - [`data()`](http://api.jquery.com/data/)
+ * - [`detach()`](http://api.jquery.com/detach/)
+ * - [`empty()`](http://api.jquery.com/empty/)
+ * - [`eq()`](http://api.jquery.com/eq/)
+ * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
+ * - [`hasClass()`](http://api.jquery.com/hasClass/)
+ * - [`html()`](http://api.jquery.com/html/)
+ * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
+ * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
+ * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
+ * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
+ * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
+ * - [`prepend()`](http://api.jquery.com/prepend/)
+ * - [`prop()`](http://api.jquery.com/prop/)
+ * - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)
+ * - [`remove()`](http://api.jquery.com/remove/)
+ * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes
+ * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
+ * - [`removeData()`](http://api.jquery.com/removeData/)
+ * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
+ * - [`text()`](http://api.jquery.com/text/)
+ * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
+ * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers
+ * - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter
+ * - [`val()`](http://api.jquery.com/val/)
+ * - [`wrap()`](http://api.jquery.com/wrap/)
+ *
+ * ## jQuery/jqLite Extras
+ * Angular also provides the following additional methods and events to both jQuery and jqLite:
+ *
+ * ### Events
+ * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
+ * on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM
+ * element before it is removed.
+ *
+ * ### Methods
+ * - `controller(name)` - retrieves the controller of the current element or its parent. By default
+ * retrieves controller associated with the `ngController` directive. If `name` is provided as
+ * camelCase directive name, then the controller for this directive will be retrieved (e.g.
+ * `'ngModel'`).
+ * - `injector()` - retrieves the injector of the current element or its parent.
+ * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
+ * element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
+ * be enabled.
+ * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
+ * current element. This getter should be used only on elements that contain a directive which starts a new isolate
+ * scope. Calling `scope()` on this element always returns the original non-isolate scope.
+ * Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
+ * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
+ * parent element is reached.
+ *
+ * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See
+ * https://github.com/angular/angular.js/issues/14251 for more information.
+ *
+ * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
+ * @returns {Object} jQuery object.

- * @description
- * Creates an injector object that can be used for retrieving services as well as for
- * dependency injection (see {@link guide/di dependency injection}).
- *
- * @param {Array.} modules A list of module functions or their aliases. See
- * {@link angular.module}. The `ng` module must be explicitly added.
- * @param {boolean=} [strictDi=false] Whether the injector should be in strict mode, which
- * disallows argument name annotation inference.
- * @returns {injector} Injector object. See {@link auto.$injector $injector}.
- *
- * @example
- * Typical usage
- * ```js
- * // create an injector
- * var $injector = angular.injector(['ng']);
- *
- * // use the injector to kick off your application
- * // use the type inference to auto inject arguments, or use implicit injection
- * $injector.invoke(function($rootScope, $compile, $document) {
- * $compile($document)($rootScope);
- * $rootScope.$digest();
- * });
- * ```
- *
- * Sometimes you want to get access to the injector of a currently running Angular app
- * from outside Angular. Perhaps, you want to inject and compile some markup after the
- * application has been bootstrapped. You can do this using the extra `injector()` added
- * to JQuery/jqLite elements. See {@link angular.element}.
- *
- * *This is fairly rare but could be the case if a third party library is injecting the
- * markup.*
- *
- * In the following example a new block of HTML containing a `ng-controller`
- * directive is added to the end of the document body by JQuery. We then compile and link
- * it into the current AngularJS scope.
- *
- * ```js
- * var $div = $('{{content.label}}
');
- * $(document.body).append($div);
- *
- * angular.element(document).injector().invoke(function($compile) {

- *
- * `$injector` is used to retrieve object instances as defined by

- *
- * # Injection Function Annotation
- *
- * JavaScript does not have annotations, and annotations are needed for dependency injection. The
- * following are all valid ways of annotating function with injection arguments and are equivalent.
- *
- * ```js
- * // inferred (only works if code not minified/obfuscated)
- * $injector.invoke(function(serviceA){});
- *
- * // annotated
- * function explicit(serviceA) {};
- * explicit.$inject = ['serviceA'];
- * $injector.invoke(explicit);
- *
- * // inline
- * $injector.invoke(['serviceA', function(serviceA){}]);
- * ```
- *
- * ## Inference
- *
- * In JavaScript calling `toString()` on a function returns the function definition. The definition
- * can then be parsed and the function arguments can be extracted. This method of discovering
- * annotations is disallowed when the injector is in strict mode.
- * *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
- * argument names.
- *
- * ## `$inject` Annotation
- * By adding an `$inject` property onto a function the injection parameters can be specified.
- *
- * ## Inline
- * As an array of injection names, where the last item in the array is the function to call.

- *
- * @description

- * function is invoked. There are three ways in which the function can be annotated with the needed

- *
- * # Argument names
- *
- * The simplest form is to extract the dependencies from the arguments of the function. This is done
- * by converting the function into a string using `toString()` method and extracting the argument
- * names.
- * ```js
- * // Given
- * function MyController($scope, $route) {
- * // ...
- * }
- *
- * // Then
- * expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
- * ```
- *
- * You can disallow this method by using strict injection mode.
- *
- * This method does not work with code minification / obfuscation. For this reason the following
- * annotation strategies are supported.
- *
- * # The `$inject` property
- *
- * If a function has an `$inject` property and its value is an array of strings, then the strings
- * represent names of services to be injected into the function.
- * ```js
- * // Given
- * var MyController = function(obfuscatedScope, obfuscatedRoute) {
- * // ...
- * }
- * // Define function dependencies
- * MyController['$inject'] = ['$scope', '$route'];
- *
- * // Then
- * expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
- * ```
- *
- * # The array notation
- *
- * It is often desirable to inline Injected functions and that's when setting the `$inject` property
- * is very inconvenient. In these situations using the array notation to specify the dependencies in
- * a way that survives minification is a better choice:
- *
- * ```js
- * // We wish to write this (not minification / obfuscation safe)
- * injector.invoke(function($compile, $rootScope) {
- * // ...
- * });
- *
- * // We are forced to write break inlining
- * var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
- * // ...
- * };
- * tmpFn.$inject = ['$compile', '$rootScope'];
- * injector.invoke(tmpFn);
- *
- * // To better support inline function the inline annotation is supported
- * injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
- * // ...
- * }]);
- *
- * // Therefore
- * expect(injector.annotate(
- * ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
- * ).toEqual(['$compile', '$rootScope']);
- * ```
- *
- * @param {Function|Array.} fn Function for which dependent service names need to
- * be retrieved as described above.
- *
- * @param {boolean=} [strictDi=false] Disallow argument name annotation inference.

- *
- * An Angular **service** is a singleton object created by a **service factory**. These **service

- *
- * When you request a service, the {@link auto.$injector $injector} is responsible for finding the

- * function to get the instance of the **service**.
- *
- * Often services have no configuration options and there is no need to add methods to the service
- * provider. The provider will be no more than a constructor function with a `$get` property. For
- * these cases the {@link auto.$provide $provide} service has additional helper methods to register
- * services without specifying a provider.
- *
- * * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the

- * services, not providers.
- * * {@link auto.$provide#factory factory(name, fn)} - registers a service **factory function**
- * that will be wrapped in a **service provider** object, whose `$get` property will contain the

- * * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function**
- * that will be wrapped in a **service provider** object, whose `$get` property will instantiate
- * a new object using the given constructor function.

- * @ngdoc method

- * Register a **service constructor**, which will be invoked with `new` to create the service

- * This is short for registering a service where its provider's `$get` property is a factory
- * function that returns an instance instantiated by the injector from the service constructor
- * function.
- *
- * Internally it looks a bit like this:
- *
- * ```
- * {
- * $get: function() {

- * }
- * }
- * ```
- *
- *
- * You should use {@link auto.$provide#service $provide.service(class)} if you define your service
- * as a type/class.
- *
- * @param {string} name The name of the instance.
- * @param {Function|Array.} constructor An injectable class (constructor function)
- * that will be instantiated.
- * @returns {Object} registered provider instance
- *
- * @example
- * Here is an example of registering a service using

- * ```js
- * var Ping = function($http) {

- * Ping.$inject = ['$http'];
- *
- * Ping.prototype.send = function() {
- * return this.$http.get('/ping');

- * $provide.service('ping', Ping);
- * ```
- * You would then inject and use this service like this:
- * ```js
- * someModule.controller('Ctrl', ['ping', function(ping) {
- * ping.send();
- * }]);

- *
- * You can find out more about using decorators in the {@link guide/decorators} guide.
- *
- * @param {string} name The name of the service to decorate.
- * @param {Function|Array.} decorator This function will be invoked when the service needs to be
- * provided and should return the decorated service instance. The function is called using
- * the {@link auto.$injector#invoke injector.invoke} method and is therefore fully injectable.
- * Local injection arguments:
- *
- * * `$delegate` - The original service instance, which can be replaced, monkey patched, configured,
- * decorated or delegated to.
- *
- * @example
- * Here we decorate the {@link ng.$log $log} service to convert warnings to errors by intercepting
- * calls to {@link ng.$log#error $log.warn()}.
- * ```js
- * $provide.decorator('$log', ['$delegate', function($delegate) {

+ * An Angular **service** is a singleton object created by a **service factory**. These **service
+ * factories** are functions which, in turn, are created by a **service provider**.
+ * The **service providers** are constructor functions. When instantiated they must contain a
+ * property called `$get`, which holds the **service factory** function.
+ *
+ * When you request a service, the {@link auto.$injector $injector} is responsible for finding the
+ * correct **service provider**, instantiating it and then calling its `$get` **service factory**
+ * function to get the instance of the **service**.
+ *
+ * Often services have no configuration options and there is no need to add methods to the service
+ * provider. The provider will be no more than a constructor function with a `$get` property. For
+ * these cases the {@link auto.$provide $provide} service has additional helper methods to register
+ * services without specifying a provider.
+ *
+ * * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the
+ * {@link auto.$injector $injector}
+ * * {@link auto.$provide#constant constant(name, obj)} - registers a value/object that can be accessed by
+ * providers and services.
+ * * {@link auto.$provide#value value(name, obj)} - registers a value/object that can only be accessed by
+ * services, not providers.
+ * * {@link auto.$provide#factory factory(name, fn)} - registers a service **factory function**
+ * that will be wrapped in a **service provider** object, whose `$get` property will contain the
+ * given factory function.
+ * * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function**
+ * that will be wrapped in a **service provider** object, whose `$get` property will instantiate
+ * a new object using the given constructor function.
+ * * {@link auto.$provide#decorator decorator(name, decorFn)} - registers a **decorator function** that
+ * will be able to modify or replace the implementation of another service.

+ * @description
+ * Compiles an HTML string or DOM into a template and produces a template function, which
+ * can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together.
+ *
+ * The compilation is a process of walking the DOM tree and matching DOM elements to
+ * {@link ng.$compileProvider#directive directives}.
+ *
+ *
+ * **Note:** This document is an in-depth reference of all directive options.
+ * For a gentle introduction to directives with examples of common use cases,
+ * see the {@link guide/directive directive guide}.
+ *
+ *
+ * ## Comprehensive Directive API
+ *
+ * There are many different options for a directive.
+ *
+ * The difference resides in the return value of the factory function.
+ * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
+ * that defines the directive properties, or just the `postLink` function (all other properties will have
+ * the default values).
+ *
+ *
+ * **Best Practice:** It's recommended to use the "directive definition object" form.
+ *
+ *
+ * Here's an example directive declared with a Directive Definition Object:
+ *
+ * ```js
+ * var myModule = angular.module(...);
+ *
+ * myModule.directive('directiveName', function factory(injectables) {
+ * var directiveDefinitionObject = {
+ * {@link $compile#-priority- priority}: 0,
+ * {@link $compile#-template- template}: '
', // or // function(tElement, tAttrs) { ... },
+ * // or
+ * // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... },
+ * {@link $compile#-transclude- transclude}: false,
+ * {@link $compile#-restrict- restrict}: 'A',
+ * {@link $compile#-templatenamespace- templateNamespace}: 'html',
+ * {@link $compile#-scope- scope}: false,
+ * {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
+ * {@link $compile#-controlleras- controllerAs}: 'stringIdentifier',
+ * {@link $compile#-bindtocontroller- bindToController}: false,
+ * {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
+ * {@link $compile#-multielement- multiElement}: false,
+ * {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) {
+ * return {
+ * {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
+ * {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
+ * }
+ * // or
+ * // return function postLink( ... ) { ... }
+ * },
+ * // or
+ * // {@link $compile#-link- link}: {
+ * // {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
+ * // {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
+ * // }
+ * // or
+ * // {@link $compile#-link- link}: function postLink( ... ) { ... }
+ * };
+ * return directiveDefinitionObject;
+ * });
+ * ```
+ *
+ *
+ * **Note:** Any unspecified options will use the default value. You can see the default values below.
+ *
+ *
+ * Therefore the above can be simplified as:
+ *
+ * ```js
+ * var myModule = angular.module(...);
+ *
+ * myModule.directive('directiveName', function factory(injectables) {
+ * var directiveDefinitionObject = {
+ * link: function postLink(scope, iElement, iAttrs) { ... }
+ * };
+ * return directiveDefinitionObject;
+ * // or
+ * // return function postLink(scope, iElement, iAttrs) { ... }
+ * });
+ * ```
+ *
+ * ### Life-cycle hooks
+ * Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the
+ * directive:
+ * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
+ * had their bindings initialized (and before the pre & post linking functions for the directives on
+ * this element). This is a good place to put initialization code for your controller.
+ * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
+ * `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
+ * object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
+ * component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will
+ * also be called when your bindings are initialized.
+ * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
+ * changes. Any actions that you wish to take in response to the changes that you detect must be
+ * invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
+ * could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
+ * be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
+ * if detecting changes, you must store the previous value(s) for comparison to the current values.
+ * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
+ * external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
+ * the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
+ * components will have their `$onDestroy()` hook called before child components.
+ * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
+ * function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
+ * Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
+ * they are waiting for their template to load asynchronously and their own compilation and linking has been
+ * suspended until that occurs.
+ *
+ * #### Comparison with Angular 2 life-cycle hooks
+ * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are
+ * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2:
+ *
+ * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`.
+ * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor.
+ * In Angular 2 you can only define hooks on the prototype of the Component class.
+ * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to
+ * `ngDoCheck` in Angular 2
+ * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
+ * propagated throughout the application.
+ * Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
+ * error or do nothing depending upon the state of `enableProdMode()`.
+ *
+ * #### Life-cycle hook examples
+ *
+ * This example shows how you can check for mutations to a Date object even though the identity of the object
+ * has not changed.
+ *
+ *
+ *
+ * angular.module('do-check-module', [])
+ * .component('app', {
+ * template:
+ * 'Month: {{ $ctrl.log | json }} ',
+ * controller: function() {
+ * var previousValue;
+ * this.log = [];
+ * this.$doCheck = function() {
+ * var currentValue = this.date && this.date.valueOf();
+ * if (previousValue !== currentValue) {
+ * this.log.push('doCheck: date mutated: ' + this.date);
+ * previousValue = currentValue;
+ * }
+ * };
+ * }
+ * });
+ *
+ *
+ *
+ *
+ *
+ * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
+ * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
+ * arrays or objects can have a negative impact on your application performance)
+ *
+ *
+ *
+ *
+ *
Add Item
+ *
Reset Items
+ *
{{ items }}
+ *
+ *
+ *
+ * angular.module('do-check-module', [])
+ * .component('test', {
+ * bindings: { items: '<' },
+ * template:
+ * '{{ $ctrl.log | json }} ',
+ * controller: function() {
+ * this.log = [];
+ *
+ * this.$doCheck = function() {
+ * if (this.items_ref !== this.items) {
+ * this.log.push('doCheck: items changed');
+ * this.items_ref = this.items;
+ * }
+ * if (!angular.equals(this.items_clone, this.items)) {
+ * this.log.push('doCheck: items mutated');
+ * this.items_clone = angular.copy(this.items);
+ * }
+ * };
+ * }
+ * });
+ *
+ *
+ *
+ *
+ * ### Directive Definition Object
+ *
+ * The directive definition object provides instructions to the {@link ng.$compile
+ * compiler}. The attributes are:
+ *
+ * #### `multiElement`
+ * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between
+ * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
+ * together as the directive elements. It is recommended that this feature be used on directives
+ * which are not strictly behavioral (such as {@link ngClick}), and which
+ * do not manipulate or replace child nodes (such as {@link ngInclude}).
+ *
+ * #### `priority`
+ * When there are multiple directives defined on a single DOM element, sometimes it
+ * is necessary to specify the order in which the directives are applied. The `priority` is used
+ * to sort the directives before their `compile` functions get called. Priority is defined as a
+ * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
+ * are also run in priority order, but post-link functions are run in reverse order. The order
+ * of directives with the same priority is undefined. The default priority is `0`.
+ *
+ * #### `terminal`
+ * If set to true then the current `priority` will be the last set of directives
+ * which will execute (any directives at the current priority will still execute
+ * as the order of execution on same `priority` is undefined). Note that expressions
+ * and other directives used in the directive's template will also be excluded from execution.
+ *
+ * #### `scope`
+ * The scope property can be `false`, `true`, or an object:
+ *
+ * * **`false` (default):** No scope will be created for the directive. The directive will use its
+ * parent's scope.
+ *
+ * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
+ * the directive's element. If multiple directives on the same element request a new scope,
+ * only one new scope is created.
+ *
+ * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's template.
+ * The 'isolate' scope differs from normal scope in that it does not prototypically
+ * inherit from its parent scope. This is useful when creating reusable components, which should not
+ * accidentally read or modify data in the parent scope. Note that an isolate scope
+ * directive without a `template` or `templateUrl` will not apply the isolate scope
+ * to its children elements.
+ *
+ * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
+ * directive's element. These local properties are useful for aliasing values for templates. The keys in
+ * the object hash map to the name of the property on the isolate scope; the values define how the property
+ * is bound to the parent scope, via matching attributes on the directive's element:
+ *
+ * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
+ * always a string since DOM attributes are strings. If no `attr` name is specified then the
+ * attribute name is assumed to be the same as the local name. Given `
` and the isolate scope definition `scope: { localName:'@myAttr' }`,
+ * the directive's scope property `localName` will reflect the interpolated value of `hello
+ * {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
+ * scope. The `name` is read from the parent scope (not the directive's scope).
+ *
+ * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
+ * passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
+ * If no `attr` name is specified then the attribute name is assumed to be the same as the local
+ * name. Given `` and the isolate scope definition `scope: {
+ * localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
+ * value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
+ * `localModel` and vice versa. Optional attributes should be marked as such with a question mark:
+ * `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't
+ * optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})
+ * will be thrown upon discovering changes to the local value, since it will be impossible to sync
+ * them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
+ * method is used for tracking changes, and the equality check is based on object identity.
+ * However, if an object literal or an array literal is passed as the binding expression, the
+ * equality check is done by value (using the {@link angular.equals} function). It's also possible
+ * to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
+ * `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional).
+ *
+ * * `<` or `` and directive definition of
+ * `scope: { localModel:'` and the isolate scope definition `scope: {
+ * localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
+ * the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
+ * via an expression to the parent scope. This can be done by passing a map of local variable names
+ * and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
+ * then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
+ *
+ * In general it's possible to apply more than one directive to one element, but there might be limitations
+ * depending on the type of scope required by the directives. The following points will help explain these limitations.
+ * For simplicity only two directives are taken into account, but it is also applicable for several directives:
+ *
+ * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
+ * * **child scope** + **no scope** => Both directives will share one single child scope
+ * * **child scope** + **child scope** => Both directives will share one single child scope
+ * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use
+ * its parent's scope
+ * * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
+ * be applied to the same element.
+ * * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives
+ * cannot be applied to the same element.
+ *
+ *
+ * #### `bindToController`
+ * This property is used to bind scope properties directly to the controller. It can be either
+ * `true` or an object hash with the same format as the `scope` property.
+ *
+ * When an isolate scope is used for a directive (see above), `bindToController: true` will
+ * allow a component to have its properties bound to the controller, rather than to scope.
+ *
+ * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
+ * properties. You can access these bindings once they have been initialized by providing a controller method called
+ * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
+ * initialized.
+ *
+ *
+ * **Deprecation warning:** if `$compileProcvider.preAssignBindingsEnabled(true)` was called, bindings for non-ES6 class
+ * controllers are bound to `this` before the controller constructor is called but this use is now deprecated. Please
+ * place initialization code that relies upon bindings inside a `$onInit` method on the controller, instead.
+ *
+ *
+ * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
+ * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
+ * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
+ * scope (useful for component directives).
+ *
+ * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
+ *
+ *
+ * #### `controller`
+ * Controller constructor function. The controller is instantiated before the
+ * pre-linking phase and can be accessed by other directives (see
+ * `require` attribute). This allows the directives to communicate with each other and augment
+ * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
+ *
+ * * `$scope` - Current scope associated with the element
+ * * `$element` - Current element
+ * * `$attrs` - Current attributes object for the element
+ * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
+ * `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
+ * * `scope`: (optional) override the scope.
+ * * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
+ * * `futureParentElement` (optional):
+ * * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
+ * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
+ * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
+ * and when the `cloneLinkingFn` is passed,
+ * as those elements need to created and cloned in a special way when they are defined outside their
+ * usual containers (e.g. like ``).
+ * * See also the `directive.templateNamespace` property.
+ * * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
+ * then the default transclusion is provided.
+ * The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
+ * `true` if the specified slot contains content (i.e. one or more DOM nodes).
+ *
+ * #### `require`
+ * Require another directive and inject its controller as the fourth argument to the linking function. The
+ * `require` property can be a string, an array or an object:
+ * * a **string** containing the name of the directive to pass to the linking function
+ * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
+ * linking function will be an array of controllers in the same order as the names in the `require` property
+ * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
+ * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
+ * controllers.
+ *
+ * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
+ * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
+ * have been constructed but before `$onInit` is called.
+ * If the name of the required controller is the same as the local name (the key), the name can be
+ * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
+ * See the {@link $compileProvider#component} helper for an example of how this can be used.
+ * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
+ * raised (unless no link function is specified and the required controllers are not being bound to the directive
+ * controller, in which case error checking is skipped). The name can be prefixed with:
+ *
+ * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
+ * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
+ * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
+ * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
+ * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
+ * `null` to the `link` fn if not found.
+ * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
+ * `null` to the `link` fn if not found.
+ *
+ *
+ * #### `controllerAs`
+ * Identifier name for a reference to the controller in the directive's scope.
+ * This allows the controller to be referenced from the directive template. This is especially
+ * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
+ * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
+ * `controllerAs` reference might overwrite a property that already exists on the parent scope.
+ *
+ *
+ * #### `restrict`
+ * String of subset of `EACM` which restricts the directive to a specific directive
+ * declaration style. If omitted, the defaults (elements and attributes) are used.
+ *
+ * * `E` - Element name (default): `
`
+ * * `C` - Class: `
`
+ * * `M` - Comment: ``
+ *
+ *
+ * #### `templateNamespace`
+ * String representing the document type used by the markup in the template.
+ * AngularJS needs this information as those elements need to be created and cloned
+ * in a special way when they are defined outside their usual containers like `` and ``.
+ *
+ * * `html` - All root nodes in the template are HTML. Root nodes may also be
+ * top-level elements such as `` or ``.
+ * * `svg` - The root nodes in the template are SVG elements (excluding ``).
+ * * `math` - The root nodes in the template are MathML elements (excluding ``).
+ *
+ * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
+ *
+ * #### `template`
+ * HTML markup that may:
+ * * Replace the contents of the directive's element (default).
+ * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
+ * * Wrap the contents of the directive's element (if `transclude` is true).
+ *
+ * Value may be:
+ *
+ * * A string. For example `{{delete_str}}
`.
+ * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
+ * function api below) and returns a string value.
+ *
+ *
+ * #### `templateUrl`
+ * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
+ *
+ * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
+ * for later when the template has been resolved. In the meantime it will continue to compile and link
+ * sibling and parent elements as though this element had not contained any directives.
+ *
+ * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
+ * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
+ * case when only one deeply nested directive has `templateUrl`.
+ *
+ * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
+ *
+ * You can specify `templateUrl` as a string representing the URL or as a function which takes two
+ * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
+ * a string value representing the url. In either case, the template URL is passed through {@link
+ * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
+ *
+ *
+ * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
+ * specify what the template should replace. Defaults to `false`.
+ *
+ * * `true` - the template will replace the directive's element.
+ * * `false` - the template will replace the contents of the directive's element.
+ *
+ * The replacement process migrates all of the attributes / classes from the old element to the new
+ * one. See the {@link guide/directive#template-expanding-directive
+ * Directives Guide} for an example.
+ *
+ * There are very few scenarios where element replacement is required for the application function,
+ * the main one being reusable custom components that are used within SVG contexts
+ * (because SVG doesn't work with custom elements in the DOM tree).
+ *
+ * #### `transclude`
+ * Extract the contents of the element where the directive appears and make it available to the directive.
+ * The contents are compiled and provided to the directive as a **transclusion function**. See the
+ * {@link $compile#transclusion Transclusion} section below.
+ *
+ *
+ * #### `compile`
+ *
+ * ```js
+ * function compile(tElement, tAttrs, transclude) { ... }
+ * ```
+ *
+ * The compile function deals with transforming the template DOM. Since most directives do not do
+ * template transformation, it is not used often. The compile function takes the following arguments:
+ *
+ * * `tElement` - template element - The element where the directive has been declared. It is
+ * safe to do template transformation on the element and child elements only.
+ *
+ * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
+ * between all directive compile functions.
+ *
+ * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
+ *
+ *
+ * **Note:** The template instance and the link instance may be different objects if the template has
+ * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
+ * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
+ * should be done in a linking function rather than in a compile function.
+ *
+
+ *
+ * **Note:** The compile function cannot handle directives that recursively use themselves in their
+ * own templates or compile functions. Compiling these directives results in an infinite loop and
+ * stack overflow errors.
+ *
+ * This can be avoided by manually using $compile in the postLink function to imperatively compile
+ * a directive's template instead of relying on automatic template compilation via `template` or
+ * `templateUrl` declaration or manual compilation inside the compile function.
+ *
+ *
+ *
+ * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
+ * e.g. does not know about the right outer scope. Please use the transclude function that is passed
+ * to the link function instead.
+ *
+
+ * A compile function can have a return value which can be either a function or an object.
+ *
+ * * returning a (post-link) function - is equivalent to registering the linking function via the
+ * `link` property of the config object when the compile function is empty.
+ *
+ * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
+ * control when a linking function should be called during the linking phase. See info about
+ * pre-linking and post-linking functions below.
+ *
+ *
+ * #### `link`
+ * This property is used only if the `compile` property is not defined.
+ *
+ * ```js
+ * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
+ * ```
+ *
+ * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
+ * executed after the template has been cloned. This is where most of the directive logic will be
+ * put.
+ *
+ * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
+ * directive for registering {@link ng.$rootScope.Scope#$watch watches}.
+ *
+ * * `iElement` - instance element - The element where the directive is to be used. It is safe to
+ * manipulate the children of the element only in `postLink` function since the children have
+ * already been linked.
+ *
+ * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
+ * between all directive linking functions.
+ *
+ * * `controller` - the directive's required controller instance(s) - Instances are shared
+ * among all directives, which allows the directives to use the controllers as a communication
+ * channel. The exact value depends on the directive's `require` property:
+ * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
+ * * `string`: the controller instance
+ * * `array`: array of controller instances
+ *
+ * If a required controller cannot be found, and it is optional, the instance is `null`,
+ * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
+ *
+ * Note that you can also require the directive's own controller - it will be made available like
+ * any other controller.
+ *
+ * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
+ * This is the same as the `$transclude` parameter of directive controllers,
+ * see {@link ng.$compile#-controller- the controller section for details}.
+ * `function([scope], cloneLinkingFn, futureParentElement)`.
+ *
+ * #### Pre-linking function
+ *
+ * Executed before the child elements are linked. Not safe to do DOM transformation since the
+ * compiler linking function will fail to locate the correct elements for linking.
+ *
+ * #### Post-linking function
+ *
+ * Executed after the child elements are linked.
+ *
+ * Note that child elements that contain `templateUrl` directives will not have been compiled
+ * and linked since they are waiting for their template to load asynchronously and their own
+ * compilation and linking has been suspended until that occurs.
+ *
+ * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
+ * for their async templates to be resolved.
+ *
+ *
+ * ### Transclusion
+ *
+ * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
+ * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
+ * scope from where they were taken.
+ *
+ * Transclusion is used (often with {@link ngTransclude}) to insert the
+ * original contents of a directive's element into a specified place in the template of the directive.
+ * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
+ * content has access to the properties on the scope from which it was taken, even if the directive
+ * has isolated scope.
+ * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
+ *
+ * This makes it possible for the widget to have private state for its template, while the transcluded
+ * content has access to its originating scope.
+ *
+ *
+ * **Note:** When testing an element transclude directive you must not place the directive at the root of the
+ * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
+ * Testing Transclusion Directives}.
+ *
+ *
+ * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
+ * directive's element, the entire element or multiple parts of the element contents:
+ *
+ * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
+ * * `'element'` - transclude the whole of the directive's element including any directives on this
+ * element that defined at a lower priority than this directive. When used, the `template`
+ * property is ignored.
+ * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
+ *
+ * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
+ *
+ * This object is a map where the keys are the name of the slot to fill and the value is an element selector
+ * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
+ * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
+ *
+ * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
+ *
+ * If the element selector is prefixed with a `?` then that slot is optional.
+ *
+ * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to
+ * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
+ *
+ * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
+ * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
+ * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
+ * injectable into the directive's controller.
+ *
+ *
+ * #### Transclusion Functions
+ *
+ * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
+ * function** to the directive's `link` function and `controller`. This transclusion function is a special
+ * **linking function** that will return the compiled contents linked to a new transclusion scope.
+ *
+ *
+ * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
+ * ngTransclude will deal with it for us.
+ *
+ *
+ * If you want to manually control the insertion and removal of the transcluded content in your directive
+ * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
+ * object that contains the compiled DOM, which is linked to the correct transclusion scope.
+ *
+ * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
+ * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
+ * content and the `scope` is the newly created transclusion scope, which the clone will be linked to.
+ *
+ *
+ * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
+ * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
+ *
+ *
+ * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
+ * attach function**:
+ *
+ * ```js
+ * var transcludedContent, transclusionScope;
+ *
+ * $transclude(function(clone, scope) {
+ * element.append(clone);
+ * transcludedContent = clone;
+ * transclusionScope = scope;
+ * });
+ * ```
+ *
+ * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
+ * associated transclusion scope:
+ *
+ * ```js
+ * transcludedContent.remove();
+ * transclusionScope.$destroy();
+ * ```
+ *
+ *
+ * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
+ * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
+ * then you are also responsible for calling `$destroy` on the transclusion scope.
+ *
+ *
+ * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
+ * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
+ * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
+ *
+ *
+ * #### Transclusion Scopes
+ *
+ * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
+ * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
+ * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
+ * was taken.
+ *
+ * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
+ * like this:
+ *
+ * ```html
+ *
+ * ```
+ *
+ * The `$parent` scope hierarchy will look like this:
+ *
+ ```
+ - $rootScope
+ - isolate
+ - transclusion
+ ```
+ *
+ * but the scopes will inherit prototypically from different scopes to their `$parent`.
+ *
+ ```
+ - $rootScope
+ - transclusion
+ - isolate
+ ```
+ *
+ *
+ * ### Attributes
+ *
+ * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
+ * `link()` or `compile()` functions. It has a variety of uses.
+ *
+ * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
+ * 'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
+ * to the attributes.
+ *
+ * * *Directive inter-communication:* All directives share the same instance of the attributes
+ * object which allows the directives to use the attributes object as inter directive
+ * communication.
+ *
+ * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
+ * allowing other directives to read the interpolated value.
+ *
+ * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
+ * that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
+ * the only way to easily get the actual value because during the linking phase the interpolation
+ * hasn't been evaluated yet and so the value is at this time set to `undefined`.
+ *
+ * ```js
+ * function linkingFn(scope, elm, attrs, ctrl) {
+ * // get the attribute value
+ * console.log(attrs.ngModel);
+ *
+ * // change the attribute
+ * attrs.$set('ngModel', 'new value');
+ *
+ * // observe changes to interpolated attribute
+ * attrs.$observe('ngModel', function(value) {
+ * console.log('ngModel has changed value to ' + value);
+ * });
+ * }
+ * ```
+ *
+ * ## Example
+ *
+ *
+ * **Note**: Typically directives are registered with `module.directive`. The example below is
+ * to illustrate how `$compile` works.
+ *

+ *
+ *
+ * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it
+ * e.g. will not use the right outer scope. Please pass the transclude function as a
+ * `parentBoundTranscludeFn` to the link function instead.
+ *
+ *

+ * (a DOM element/tree) to a scope. Where:
+ *
+ * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
+ * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
+ * `template` and call the `cloneAttachFn` function allowing the caller to attach the
+ * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
+ * called as: {{total}}
')(scope);
+ * ```
+ *
+ * - if on the other hand, you need the element to be cloned, the view reference from the original
+ * example would not point to the clone, but rather to the original template that was cloned. In
+ * this case, you can access the clone via the cloneAttachFn:
+ * ```js
+ * var templateElement = angular.element('{{total}}
'),
+ * scope = ....;
+ *
+ * var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
+ * //attach the clone to DOM document at the right place
+ * });
+ *
+ * //now we have reference to the cloned DOM via `clonedElement`
+ * ```

-/**

- * @name $compile
- * @kind function
- *
- * @description
- * Compiles an HTML string or DOM into a template and produces a template function, which
- * can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together.
- *
- * The compilation is a process of walking the DOM tree and matching DOM elements to
- * {@link ng.$compileProvider#directive directives}.
- *
- *
- * **Note:** This document is an in-depth reference of all directive options.
- * For a gentle introduction to directives with examples of common use cases,
- * see the {@link guide/directive directive guide}.
- *
- *
- * ## Comprehensive Directive API
- *
- * There are many different options for a directive.
- *
- * The difference resides in the return value of the factory function.
- * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
- * that defines the directive properties, or just the `postLink` function (all other properties will have
- * the default values).
- *
- *
- * **Best Practice:** It's recommended to use the "directive definition object" form.
- *
- *
- * Here's an example directive declared with a Directive Definition Object:
- *
- * ```js
- * var myModule = angular.module(...);
- *
- * myModule.directive('directiveName', function factory(injectables) {
- * var directiveDefinitionObject = {
- * {@link $compile#-priority- priority}: 0,
- * {@link $compile#-template- template}: '
', // or // function(tElement, tAttrs) { ... },
- * // or
- * // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... },
- * {@link $compile#-transclude- transclude}: false,
- * {@link $compile#-restrict- restrict}: 'A',
- * {@link $compile#-templatenamespace- templateNamespace}: 'html',
- * {@link $compile#-scope- scope}: false,
- * {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
- * {@link $compile#-controlleras- controllerAs}: 'stringIdentifier',
- * {@link $compile#-bindtocontroller- bindToController}: false,
- * {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
- * {@link $compile#-multielement- multiElement}: false,
- * {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) {
- * return {
- * {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
- * {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
- * }
- * // or
- * // return function postLink( ... ) { ... }
- * },
- * // or
- * // {@link $compile#-link- link}: {
- * // {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
- * // {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
- * // }
- * // or
- * // {@link $compile#-link- link}: function postLink( ... ) { ... }
- * };
- * return directiveDefinitionObject;
- * });
- * ```
- *
- *
- * **Note:** Any unspecified options will use the default value. You can see the default values below.
- *
- *
- * Therefore the above can be simplified as:
- *
- * ```js
- * var myModule = angular.module(...);
- *
- * myModule.directive('directiveName', function factory(injectables) {
- * var directiveDefinitionObject = {
- * link: function postLink(scope, iElement, iAttrs) { ... }
- * };
- * return directiveDefinitionObject;
- * // or
- * // return function postLink(scope, iElement, iAttrs) { ... }
- * });
- * ```
- *
- * ### Life-cycle hooks
- * Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the
- * directive:
- * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
- * had their bindings initialized (and before the pre & post linking functions for the directives on
- * this element). This is a good place to put initialization code for your controller.
- * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
- * `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
- * object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
- * component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will
- * also be called when your bindings are initialized.
- * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
- * changes. Any actions that you wish to take in response to the changes that you detect must be
- * invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
- * could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
- * be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
- * if detecting changes, you must store the previous value(s) for comparison to the current values.
- * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
- * external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
- * the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
- * components will have their `$onDestroy()` hook called before child components.
- * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
- * function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
- * Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
- * they are waiting for their template to load asynchronously and their own compilation and linking has been
- * suspended until that occurs.
- *
- * #### Comparison with Angular 2 life-cycle hooks
- * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are
- * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2:
- *
- * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`.
- * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor.
- * In Angular 2 you can only define hooks on the prototype of the Component class.
- * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to
- * `ngDoCheck` in Angular 2
- * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
- * propagated throughout the application.
- * Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
- * error or do nothing depending upon the state of `enableProdMode()`.
- *
- * #### Life-cycle hook examples
- *
- * This example shows how you can check for mutations to a Date object even though the identity of the object
- * has not changed.
- *
- *
- *
- * angular.module('do-check-module', [])
- * .component('app', {
- * template:
- * 'Month: {{ $ctrl.log | json }} ',
- * controller: function() {
- * var previousValue;
- * this.log = [];
- * this.$doCheck = function() {
- * var currentValue = this.date && this.date.valueOf();
- * if (previousValue !== currentValue) {
- * this.log.push('doCheck: date mutated: ' + this.date);
- * previousValue = currentValue;
- * }
- * };
- * }
- * });
- *
- *
- *
- *
- *
- * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
- * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
- * arrays or objects can have a negative impact on your application performance)
- *
- *
- *
- *
- *
Add Item
- *
Reset Items
- *
{{ items }}
- *
- *
- *
- * angular.module('do-check-module', [])
- * .component('test', {
- * bindings: { items: '<' },
- * template:
- * '{{ $ctrl.log | json }} ',
- * controller: function() {
- * this.log = [];
- *
- * this.$doCheck = function() {
- * if (this.items_ref !== this.items) {
- * this.log.push('doCheck: items changed');
- * this.items_ref = this.items;
- * }
- * if (!angular.equals(this.items_clone, this.items)) {
- * this.log.push('doCheck: items mutated');
- * this.items_clone = angular.copy(this.items);
- * }
- * };
- * }
- * });
- *
- *
- *
- *
- * ### Directive Definition Object
- *
- * The directive definition object provides instructions to the {@link ng.$compile
- * compiler}. The attributes are:
- *
- * #### `multiElement`
- * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between
- * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
- * together as the directive elements. It is recommended that this feature be used on directives
- * which are not strictly behavioral (such as {@link ngClick}), and which
- * do not manipulate or replace child nodes (such as {@link ngInclude}).
- *
- * #### `priority`
- * When there are multiple directives defined on a single DOM element, sometimes it
- * is necessary to specify the order in which the directives are applied. The `priority` is used
- * to sort the directives before their `compile` functions get called. Priority is defined as a
- * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
- * are also run in priority order, but post-link functions are run in reverse order. The order
- * of directives with the same priority is undefined. The default priority is `0`.
- *
- * #### `terminal`
- * If set to true then the current `priority` will be the last set of directives
- * which will execute (any directives at the current priority will still execute
- * as the order of execution on same `priority` is undefined). Note that expressions
- * and other directives used in the directive's template will also be excluded from execution.
- *
- * #### `scope`
- * The scope property can be `false`, `true`, or an object:
- *
- * * **`false` (default):** No scope will be created for the directive. The directive will use its
- * parent's scope.
- *
- * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
- * the directive's element. If multiple directives on the same element request a new scope,
- * only one new scope is created.
- *
- * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's template.
- * The 'isolate' scope differs from normal scope in that it does not prototypically
- * inherit from its parent scope. This is useful when creating reusable components, which should not
- * accidentally read or modify data in the parent scope. Note that an isolate scope
- * directive without a `template` or `templateUrl` will not apply the isolate scope
- * to its children elements.
- *
- * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
- * directive's element. These local properties are useful for aliasing values for templates. The keys in
- * the object hash map to the name of the property on the isolate scope; the values define how the property
- * is bound to the parent scope, via matching attributes on the directive's element:
- *
- * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
- * always a string since DOM attributes are strings. If no `attr` name is specified then the
- * attribute name is assumed to be the same as the local name. Given `` and the isolate scope definition `scope: { localName:'@myAttr' }`,
- * the directive's scope property `localName` will reflect the interpolated value of `hello
- * {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
- * scope. The `name` is read from the parent scope (not the directive's scope).
- *
- * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
- * passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
- * If no `attr` name is specified then the attribute name is assumed to be the same as the local
- * name. Given `` and the isolate scope definition `scope: {
- * localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
- * value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
- * `localModel` and vice versa. Optional attributes should be marked as such with a question mark:
- * `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't
- * optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})
- * will be thrown upon discovering changes to the local value, since it will be impossible to sync
- * them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
- * method is used for tracking changes, and the equality check is based on object identity.
- * However, if an object literal or an array literal is passed as the binding expression, the
- * equality check is done by value (using the {@link angular.equals} function). It's also possible
- * to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
- * `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional).
- *
- * * `<` or `` and directive definition of
- * `scope: { localModel:'` and the isolate scope definition `scope: {
- * localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
- * the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
- * via an expression to the parent scope. This can be done by passing a map of local variable names
- * and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
- * then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
- *
- * In general it's possible to apply more than one directive to one element, but there might be limitations
- * depending on the type of scope required by the directives. The following points will help explain these limitations.
- * For simplicity only two directives are taken into account, but it is also applicable for several directives:
- *
- * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
- * * **child scope** + **no scope** => Both directives will share one single child scope
- * * **child scope** + **child scope** => Both directives will share one single child scope
- * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use
- * its parent's scope
- * * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
- * be applied to the same element.
- * * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives
- * cannot be applied to the same element.
- *
- *
- * #### `bindToController`
- * This property is used to bind scope properties directly to the controller. It can be either
- * `true` or an object hash with the same format as the `scope` property.
- *
- * When an isolate scope is used for a directive (see above), `bindToController: true` will
- * allow a component to have its properties bound to the controller, rather than to scope.
- *
- * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
- * properties. You can access these bindings once they have been initialized by providing a controller method called
- * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
- * initialized.
- *
- *
- * **Deprecation warning:** if `$compileProcvider.preAssignBindingsEnabled(true)` was called, bindings for non-ES6 class
- * controllers are bound to `this` before the controller constructor is called but this use is now deprecated. Please
- * place initialization code that relies upon bindings inside a `$onInit` method on the controller, instead.
- *
- *
- * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
- * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
- * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
- * scope (useful for component directives).
- *
- * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
- *
- *
- * #### `controller`
- * Controller constructor function. The controller is instantiated before the
- * pre-linking phase and can be accessed by other directives (see
- * `require` attribute). This allows the directives to communicate with each other and augment
- * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
- *
- * * `$scope` - Current scope associated with the element
- * * `$element` - Current element
- * * `$attrs` - Current attributes object for the element
- * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
- * `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
- * * `scope`: (optional) override the scope.
- * * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
- * * `futureParentElement` (optional):
- * * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
- * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
- * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
- * and when the `cloneLinkingFn` is passed,
- * as those elements need to created and cloned in a special way when they are defined outside their
- * usual containers (e.g. like ``).
- * * See also the `directive.templateNamespace` property.
- * * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
- * then the default transclusion is provided.
- * The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
- * `true` if the specified slot contains content (i.e. one or more DOM nodes).
- *
- * #### `require`
- * Require another directive and inject its controller as the fourth argument to the linking function. The
- * `require` property can be a string, an array or an object:
- * * a **string** containing the name of the directive to pass to the linking function
- * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
- * linking function will be an array of controllers in the same order as the names in the `require` property
- * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
- * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
- * controllers.
- *
- * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
- * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
- * have been constructed but before `$onInit` is called.
- * If the name of the required controller is the same as the local name (the key), the name can be
- * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
- * See the {@link $compileProvider#component} helper for an example of how this can be used.
- * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
- * raised (unless no link function is specified and the required controllers are not being bound to the directive
- * controller, in which case error checking is skipped). The name can be prefixed with:
- *
- * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
- * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
- * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
- * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
- * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
- * `null` to the `link` fn if not found.
- * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
- * `null` to the `link` fn if not found.
- *
- *
- * #### `controllerAs`
- * Identifier name for a reference to the controller in the directive's scope.
- * This allows the controller to be referenced from the directive template. This is especially
- * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
- * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
- * `controllerAs` reference might overwrite a property that already exists on the parent scope.
- *
- *
- * #### `restrict`
- * String of subset of `EACM` which restricts the directive to a specific directive
- * declaration style. If omitted, the defaults (elements and attributes) are used.
- *
- * * `E` - Element name (default): `
`
- * * `C` - Class: `
`
- * * `M` - Comment: ``
- *
- *
- * #### `templateNamespace`
- * String representing the document type used by the markup in the template.
- * AngularJS needs this information as those elements need to be created and cloned
- * in a special way when they are defined outside their usual containers like `` and ``.
- *
- * * `html` - All root nodes in the template are HTML. Root nodes may also be
- * top-level elements such as `` or ``.
- * * `svg` - The root nodes in the template are SVG elements (excluding ``).
- * * `math` - The root nodes in the template are MathML elements (excluding ``).
- *
- * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
- *
- * #### `template`
- * HTML markup that may:
- * * Replace the contents of the directive's element (default).
- * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
- * * Wrap the contents of the directive's element (if `transclude` is true).
- *
- * Value may be:
- *
- * * A string. For example `{{delete_str}}
`.
- * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
- * function api below) and returns a string value.
- *
- *
- * #### `templateUrl`
- * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
- *
- * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
- * for later when the template has been resolved. In the meantime it will continue to compile and link
- * sibling and parent elements as though this element had not contained any directives.
- *
- * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
- * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
- * case when only one deeply nested directive has `templateUrl`.
- *
- * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
- *
- * You can specify `templateUrl` as a string representing the URL or as a function which takes two
- * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
- * a string value representing the url. In either case, the template URL is passed through {@link
- * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
- *
- *
- * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
- * specify what the template should replace. Defaults to `false`.
- *
- * * `true` - the template will replace the directive's element.
- * * `false` - the template will replace the contents of the directive's element.
- *
- * The replacement process migrates all of the attributes / classes from the old element to the new
- * one. See the {@link guide/directive#template-expanding-directive
- * Directives Guide} for an example.
- *
- * There are very few scenarios where element replacement is required for the application function,
- * the main one being reusable custom components that are used within SVG contexts
- * (because SVG doesn't work with custom elements in the DOM tree).
- *
- * #### `transclude`
- * Extract the contents of the element where the directive appears and make it available to the directive.
- * The contents are compiled and provided to the directive as a **transclusion function**. See the
- * {@link $compile#transclusion Transclusion} section below.
- *
- *
- * #### `compile`
- *
- * ```js
- * function compile(tElement, tAttrs, transclude) { ... }
- * ```
- *
- * The compile function deals with transforming the template DOM. Since most directives do not do
- * template transformation, it is not used often. The compile function takes the following arguments:
- *
- * * `tElement` - template element - The element where the directive has been declared. It is
- * safe to do template transformation on the element and child elements only.
- *
- * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
- * between all directive compile functions.
- *
- * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
- *
- *
- * **Note:** The template instance and the link instance may be different objects if the template has
- * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
- * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
- * should be done in a linking function rather than in a compile function.
- *
-
- *
- * **Note:** The compile function cannot handle directives that recursively use themselves in their
- * own templates or compile functions. Compiling these directives results in an infinite loop and
- * stack overflow errors.
- *
- * This can be avoided by manually using $compile in the postLink function to imperatively compile
- * a directive's template instead of relying on automatic template compilation via `template` or
- * `templateUrl` declaration or manual compilation inside the compile function.
- *
- *
- *
- * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
- * e.g. does not know about the right outer scope. Please use the transclude function that is passed
- * to the link function instead.
- *
-
- * A compile function can have a return value which can be either a function or an object.
- *
- * * returning a (post-link) function - is equivalent to registering the linking function via the
- * `link` property of the config object when the compile function is empty.
- *
- * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
- * control when a linking function should be called during the linking phase. See info about
- * pre-linking and post-linking functions below.
- *
- *
- * #### `link`
- * This property is used only if the `compile` property is not defined.
- *
- * ```js
- * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
- * ```
- *
- * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
- * executed after the template has been cloned. This is where most of the directive logic will be
- * put.
- *
- * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
- * directive for registering {@link ng.$rootScope.Scope#$watch watches}.
- *
- * * `iElement` - instance element - The element where the directive is to be used. It is safe to
- * manipulate the children of the element only in `postLink` function since the children have
- * already been linked.
- *
- * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
- * between all directive linking functions.
- *
- * * `controller` - the directive's required controller instance(s) - Instances are shared
- * among all directives, which allows the directives to use the controllers as a communication
- * channel. The exact value depends on the directive's `require` property:
- * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
- * * `string`: the controller instance
- * * `array`: array of controller instances
- *
- * If a required controller cannot be found, and it is optional, the instance is `null`,
- * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
- *
- * Note that you can also require the directive's own controller - it will be made available like
- * any other controller.
- *
- * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
- * This is the same as the `$transclude` parameter of directive controllers,
- * see {@link ng.$compile#-controller- the controller section for details}.
- * `function([scope], cloneLinkingFn, futureParentElement)`.
- *
- * #### Pre-linking function
- *
- * Executed before the child elements are linked. Not safe to do DOM transformation since the
- * compiler linking function will fail to locate the correct elements for linking.
- *
- * #### Post-linking function
- *
- * Executed after the child elements are linked.
- *
- * Note that child elements that contain `templateUrl` directives will not have been compiled
- * and linked since they are waiting for their template to load asynchronously and their own
- * compilation and linking has been suspended until that occurs.
- *
- * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
- * for their async templates to be resolved.
- *
- *
- * ### Transclusion
- *
- * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
- * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
- * scope from where they were taken.
- *
- * Transclusion is used (often with {@link ngTransclude}) to insert the
- * original contents of a directive's element into a specified place in the template of the directive.
- * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
- * content has access to the properties on the scope from which it was taken, even if the directive
- * has isolated scope.
- * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
- *
- * This makes it possible for the widget to have private state for its template, while the transcluded
- * content has access to its originating scope.
- *
- *
- * **Note:** When testing an element transclude directive you must not place the directive at the root of the
- * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
- * Testing Transclusion Directives}.
- *
- *
- * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
- * directive's element, the entire element or multiple parts of the element contents:
- *
- * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
- * * `'element'` - transclude the whole of the directive's element including any directives on this
- * element that defined at a lower priority than this directive. When used, the `template`
- * property is ignored.
- * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
- *
- * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
- *
- * This object is a map where the keys are the name of the slot to fill and the value is an element selector
- * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
- * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
- *
- * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
- *
- * If the element selector is prefixed with a `?` then that slot is optional.
- *
- * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to
- * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
- *
- * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
- * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
- * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
- * injectable into the directive's controller.
- *
- *
- * #### Transclusion Functions
- *
- * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
- * function** to the directive's `link` function and `controller`. This transclusion function is a special
- * **linking function** that will return the compiled contents linked to a new transclusion scope.
- *
- *
- * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
- * ngTransclude will deal with it for us.
- *
- *
- * If you want to manually control the insertion and removal of the transcluded content in your directive
- * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
- * object that contains the compiled DOM, which is linked to the correct transclusion scope.
- *
- * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
- * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
- * content and the `scope` is the newly created transclusion scope, which the clone will be linked to.
- *
- *
- * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
- * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
- *
- *
- * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
- * attach function**:
- *
- * ```js
- * var transcludedContent, transclusionScope;
- *
- * $transclude(function(clone, scope) {
- * element.append(clone);
- * transcludedContent = clone;
- * transclusionScope = scope;
- * });
- * ```
- *
- * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
- * associated transclusion scope:
- *
- * ```js
- * transcludedContent.remove();
- * transclusionScope.$destroy();
- * ```
- *
- *
- * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
- * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
- * then you are also responsible for calling `$destroy` on the transclusion scope.
- *
- *
- * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
- * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
- * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
- *
- *
- * #### Transclusion Scopes
- *
- * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
- * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
- * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
- * was taken.
- *
- * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
- * like this:
- *
- * ```html
- *
- * ```
- *
- * The `$parent` scope hierarchy will look like this:
- *
- ```
- - $rootScope
- - isolate
- - transclusion
- ```
- *
- * but the scopes will inherit prototypically from different scopes to their `$parent`.
- *
- ```
- - $rootScope
- - transclusion
- - isolate
- ```
- *
- *
- * ### Attributes
- *
- * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
- * `link()` or `compile()` functions. It has a variety of uses.
- *
- * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
- * 'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
- * to the attributes.
- *
- * * *Directive inter-communication:* All directives share the same instance of the attributes
- * object which allows the directives to use the attributes object as inter directive
- * communication.
- *
- * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
- * allowing other directives to read the interpolated value.
- *
- * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
- * that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
- * the only way to easily get the actual value because during the linking phase the interpolation
- * hasn't been evaluated yet and so the value is at this time set to `undefined`.
- *
- * ```js
- * function linkingFn(scope, elm, attrs, ctrl) {
- * // get the attribute value
- * console.log(attrs.ngModel);
- *
- * // change the attribute
- * attrs.$set('ngModel', 'new value');
- *
- * // observe changes to interpolated attribute
- * attrs.$observe('ngModel', function(value) {
- * console.log('ngModel has changed value to ' + value);
- * });
- * }
- * ```
- *
- * ## Example
- *
- *
- * **Note**: Typically directives are registered with `module.directive`. The example below is
- * to illustrate how `$compile` works.
- *
- *
-
-
-
-
-
-
- it('should auto compile', function() {
- var textarea = $('textarea');
- var output = $('div[compile]');
- // The initial state reads 'Hello Angular'.
- expect(output.getText()).toBe('Hello Angular');
- textarea.clear();
- textarea.sendKeys('{{name}}!');
- expect(output.getText()).toBe('Angular!');
- });
-
-
-
- *
- *
- * @param {string|DOMElement} element Element or HTML string to compile into a template function.
- * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED.
- *
- *
- * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it
- * e.g. will not use the right outer scope. Please pass the transclude function as a
- * `parentBoundTranscludeFn` to the link function instead.
- *
- *
- * @param {number} maxPriority only apply directives lower than given priority (Only effects the
- * root element(s), not their children)
- * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template
- * (a DOM element/tree) to a scope. Where:
- *
- * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
- * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
- * `template` and call the `cloneAttachFn` function allowing the caller to attach the
- * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
- * called as: {{total}}
')(scope);
- * ```
- *
- * - if on the other hand, you need the element to be cloned, the view reference from the original
- * example would not point to the clone, but rather to the original template that was cloned. In
- * this case, you can access the clone via the cloneAttachFn:
- * ```js
- * var templateElement = angular.element('{{total}}
'),
- * scope = ....;
- *
- * var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
- * //attach the clone to DOM document at the right place
- * });
- *
- * //now we have reference to the cloned DOM via `clonedElement`
- * ```
- *
- *
- * For information on how the compiler works, see the
- * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

- * ### Double Compilation
- *
- Double compilation occurs when an already compiled part of the DOM gets
- compiled again. This is an undesired effect and can lead to misbehaving directives, performance issues,
- and memory leaks. Refer to the Compiler Guide {@link guide/compiler#double-compilation-and-how-to-avoid-it
- section on double compilation} for an in-depth explanation and ways to avoid it.

* @description
+ * Any uncaught exception in angular expressions is delegated to this service.
+ * The default implementation simply delegates to `$log.error` which logs it into
+ * the browser console.
*
- * Configure $http service to combine processing of multiple http responses received at around
- * the same time via {@link ng.$rootScope.Scope#$applyAsync $rootScope.$applyAsync}. This can result in
- * significant performance improvement for bigger applications that make many HTTP requests
- * concurrently (common during application bootstrap).
+ * In unit tests, if `angular-mocks.js` is loaded, this service is overridden by
+ * {@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing.
*
- * Defaults to false. If no value is specified, returns the current configured value.
+ * ## Example:
*
- * @param {boolean=} value If true, when requests are loaded, they will schedule a deferred
- * "apply" on the next tick, giving time for subsequent requests in a roughly ~10ms window
- * to load and share the same digest cycle.
+ * The example below will overwrite the default `$exceptionHandler` in order to (a) log uncaught
+ * errors to the backend for later inspection by the developers and (b) to use `$log.warn()` instead
+ * of `$log.error()`.
*
- * @returns {boolean|Object} If a value is specified, returns the $httpProvider for chaining.
- * otherwise, returns the current configured value.

- * pre-processing of request or postprocessing of responses.
+ * Accept: application/json, text/plain, \*/\*
- * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
- * - `Content-Type: application/json`
- * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
- * - `Content-Type: application/json`
- *
- * To add or overwrite these defaults, simply add or remove a property from these configuration
- * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
- * with the lowercased HTTP method name as the key, e.g.
- * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
- *
- * The defaults can also be set at runtime via the `$http.defaults` object in the same
- * fashion. For example:
- *
- * ```
- * module.run(function($http) {
- * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
- * });
- * ```
- *
- * In addition, you can supply a `headers` property in the config object passed when
- * calling `$http(config)`, which overrides the defaults without changing them globally.
- *
- * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
- * Use the `headers` property, setting the desired header to `undefined`. For example:
- *
- * ```js
- * var req = {
- * method: 'POST',
- * url: 'http://example.com',
- * headers: {
- * 'Content-Type': undefined
- * },
- * data: { test: 'test' }
- * }
- *
- * $http(req).then(function(){...}, function(){...});
- * ```
- *
- * ## Transforming Requests and Responses
- *
- * Both requests and responses can be transformed using transformation functions: `transformRequest`
- * and `transformResponse`. These properties can be a single function that returns
- * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
- * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
- *
- *
- * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
- * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
- * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
- * function will be reflected on the scope and in any templates where the object is data-bound.
- * To prevent this, transform functions should have no side-effects.
- * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
- *
- *
- * ### Default Transformations
- *
- * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
- * `defaults.transformResponse` properties. If a request does not provide its own transformations
- * then these will be applied.
*
- * You can augment or replace the default transformations by modifying these properties by adding to or
- * replacing the array.
+ * Default {@link $http `$http`} params serializer that converts objects to strings
+ * according to the following rules:
*
- * Angular provides the following default transformations:
+ * * `{'foo': 'bar'}` results in `foo=bar`
+ * * `{'foo': Date.now()}` results in `foo=2015-04-01T09%3A50%3A49.262Z` (`toISOString()` and encoded representation of a Date object)
+ * * `{'foo': ['bar', 'baz']}` results in `foo=bar&foo=baz` (repeated key for each array element)
+ * * `{'foo': {'bar':'baz'}}` results in `foo=%7B%22bar%22%3A%22baz%22%7D` (stringified and encoded representation of an object)
*
- * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
- *
- * - If the `data` property of the request configuration object contains an object, serialize it
- * into JSON format.
- *
- * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
- *
- * - If XSRF prefix is detected, strip it (see Security Considerations section below).
- * - If JSON response is detected, deserialize it using a JSON parser.
- *
- *
- * ### Overriding the Default Transformations Per Request
+ * Note that serializer will sort the request parameters alphabetically.

*
- * If you wish to override the request/response transformations only for a single request then provide
- * `transformRequest` and/or `transformResponse` properties on the configuration object passed
- * into `$http`.
+ * @description
*
- * Note that if you provide these properties on the config object the default transformations will be
- * overwritten. If you wish to augment the default transformations then you must include them in your
- * local transformation array.
+ * Alternative {@link $http `$http`} params serializer that follows
+ * jQuery's [`param()`](http://api.jquery.com/jquery.param/) method logic.
+ * The serializer will also sort the params alphabetically.
*
- * The following code demonstrates adding a new response transformation to be run after the default response
- * transformations have been run.
+ * To use it for serializing `$http` request parameters, set it as the `paramSerializer` property:
*
* ```js
- * function appendTransform(defaults, transform) {
- *
- * // We can't guarantee that the default transformation is an array
- * defaults = angular.isArray(defaults) ? defaults : [defaults];
- *
- * // Append the new transformation to the defaults
- * return defaults.concat(transform);
- * }
- *
* $http({
- * url: '...',
+ * url: myUrl,
* method: 'GET',
- * transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
- * return doTransform(value);
- * })
+ * params: myParams,
+ * paramSerializer: '$httpParamSerializerJQLike'
* });
* ```
*
+ * It is also possible to set it as the default `paramSerializer` in the
+ * {@link $httpProvider#defaults `$httpProvider`}.
*
- * ## Caching
- *
- * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
- * set the config.cache value or the default cache value to TRUE or to a cache object (created
- * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
- * precedence over the default cache value.
- *
- * In order to:
- * * cache all responses - set the default cache value to TRUE or to a cache object
- * * cache a specific response - set config.cache value to TRUE or to a cache object
- *
- * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
- * then the default `$cacheFactory("$http")` object is used.
- *
- * The default cache value can be set by updating the
- * {@link ng.$http#defaults `$http.defaults.cache`} property or the
- * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
- *
- * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
- * the relevant cache object. The next time the same request is made, the response is returned
- * from the cache without sending a request to the server.
- *
- * Take note that:
- *
- * * Only GET and JSONP requests are cached.
- * * The cache key is the request URL including search parameters; headers are not considered.
- * * Cached responses are returned asynchronously, in the same way as responses from the server.
- * * If multiple identical requests are made using the same cache, which is not yet populated,
- * one request will be made to the server and remaining requests will return the same response.
- * * A cache-control header on the response does not affect if or how responses are cached.
- *
- *
- * ## Interceptors
- *
- * Before you start creating interceptors, be sure to understand the
- * {@link ng.$q $q and deferred/promise APIs}.
- *
- * For purposes of global error handling, authentication, or any kind of synchronous or
- * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
- * able to intercept requests before they are handed to the server and
- * responses before they are handed over to the application code that
- * initiated these requests. The interceptors leverage the {@link ng.$q
- * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
- *
- * The interceptors are service factories that are registered with the `$httpProvider` by
- * adding them to the `$httpProvider.interceptors` array. The factory is called and
- * injected with dependencies (if specified) and returns the interceptor.
- *
- * There are two kinds of interceptors (and two kinds of rejection interceptors):
- *
- * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
- * modify the `config` object or create a new one. The function needs to return the `config`
- * object directly, or a promise containing the `config` or a new `config` object.
- * * `requestError`: interceptor gets called when a previous interceptor threw an error or
- * resolved with a rejection.
- * * `response`: interceptors get called with http `response` object. The function is free to
- * modify the `response` object or create a new one. The function needs to return the `response`
- * object directly, or as a promise containing the `response` or a new `response` object.
- * * `responseError`: interceptor gets called when a previous interceptor threw an error or
- * resolved with a rejection.
- *
+ * Additionally, you can inject the serializer and use it explicitly, for example to serialize
+ * form data for submission:
*
* ```js
- * // register the interceptor as a service
- * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
- * return {
- * // optional method
- * 'request': function(config) {
- * // do something on success
- * return config;
- * },
- *
- * // optional method
- * 'requestError': function(rejection) {
- * // do something on error
- * if (canRecover(rejection)) {
- * return responseOrNewPromise
- * }
- * return $q.reject(rejection);
- * },
- *
- *
+ * .controller(function($http, $httpParamSerializerJQLike) {
+ * //...
*
- * // optional method
- * 'response': function(response) {
- * // do something on success
- * return response;
- * },
- *
- * // optional method
- * 'responseError': function(rejection) {
- * // do something on error
- * if (canRecover(rejection)) {
- * return responseOrNewPromise
- * }
- * return $q.reject(rejection);
- * }
- * };
- * });
- *
- * $httpProvider.interceptors.push('myHttpInterceptor');
- *
- *
- * // alternatively, register the interceptor via an anonymous factory
- * $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
- * return {
- * 'request': function(config) {
- * // same as above
- * },
- *
- * 'response': function(response) {
- * // same as above
- * }
- * };
+ * $http({
+ * url: myUrl,
+ * method: 'POST',
+ * data: $httpParamSerializerJQLike(myData),
+ * headers: {
+ * 'Content-Type': 'application/x-www-form-urlencoded'
+ * }
* });
- * ```
- *
- * ## Security Considerations
- *
- * When designing web applications, consider security threats from:
- *
- * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
- * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
- *
- * Both server and the client must cooperate in order to eliminate these threats. Angular comes
- * pre-configured with strategies that address these issues, but for this to work backend server
- * cooperation is required.
- *
- * ### JSON Vulnerability Protection
- *
- * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
- * allows third party website to turn your JSON resource URL into
- * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
- * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
- * Angular will automatically strip the prefix before processing it as JSON.
- *
- * For example if your server needs to return:
- * ```js
- * ['one','two']
- * ```
*
- * which is vulnerable to attack, your server can return:
- * ```js
- * )]}',
- * ['one','two']
+ * });
* ```
*
- * Angular will strip the prefix, before processing the JSON.
- *
- *
- * ### Cross Site Request Forgery (XSRF) Protection
- *
- * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
- * which the attacker can trick an authenticated user into unknowingly executing actions on your
- * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the
- * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
- * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the
- * cookie, your server can be assured that the XHR came from JavaScript running on your domain.
- * The header will not be set for cross-domain requests.
- *
- * To take advantage of this, your server needs to set a token in a JavaScript readable session
- * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
- * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
- * that only JavaScript running on your domain could have sent the request. The token must be
- * unique for each user and must be verifiable by the server (to prevent the JavaScript from
- * making up its own tokens). We recommend that the token is a digest of your site's
- * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))
- * for added security.
- *
- * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
- * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
- * or the per-request config object.
- *
- * In order to prevent collisions in environments where multiple Angular apps share the
- * same domain or subdomain, we recommend that each application uses unique cookie name.
- *
- * @param {object} config Object describing the request to be made and how it should be
- * processed. The object has following properties:
- *
- * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
- * - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested;
- * or an object created by a call to `$sce.trustAsResourceUrl(url)`.
- * - **params** – `{Object.}` – Map of strings or objects which will be serialized
- * with the `paramSerializer` and appended as GET parameters.
- * - **data** – `{string|Object}` – Data to be sent as the request message data.
- * - **headers** – `{Object}` – Map of strings or functions which return strings representing
- * HTTP headers to send to the server. If the return value of a function is null, the
- * header will not be sent. Functions accept a config object as an argument.
- * - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
- * To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
- * The handler will be called in the context of a `$apply` block.
- * - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
- * object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
- * The handler will be called in the context of a `$apply` block.
- * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
- * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
- * - **transformRequest** –
- * `{function(data, headersGetter)|Array.}` –
- * transform function or an array of such functions. The transform function takes the http
- * request body and headers and returns its transformed (typically serialized) version.
- * See {@link ng.$http#overriding-the-default-transformations-per-request
- * Overriding the Default Transformations}
- * - **transformResponse** –
- * `{function(data, headersGetter, status)|Array.}` –
- * transform function or an array of such functions. The transform function takes the http
- * response body, headers and status and returns its transformed (typically deserialized) version.
- * See {@link ng.$http#overriding-the-default-transformations-per-request
- * Overriding the Default Transformations}
- * - **paramSerializer** - `{string|function(Object):string}` - A function used to
- * prepare the string representation of request parameters (specified as an object).
- * If specified as string, it is interpreted as function registered with the
- * {@link $injector $injector}, which means you can create your own serializer
- * by registering it as a {@link auto.$provide#service service}.
- * The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
- * alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
- * - **cache** – `{boolean|Object}` – A boolean value or object created with
- * {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
- * See {@link $http#caching $http Caching} for more information.
- * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
- * that should abort the request when resolved.
- * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
- * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
- * for more information.
- * - **responseType** - `{string}` - see
- * [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
- *
- * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object
- * when the request succeeds or fails.
- *
- *
- * @property {Array.} pendingRequests Array of config objects for currently pending
- * requests. This is primarily meant to be used for debugging purposes.

+ *
+ * @description
+ * The `$http` service is a core Angular service that facilitates communication with the remote
+ * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
+ * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
+ *
+ * For unit testing applications that use `$http` service, see
+ * {@link ngMock.$httpBackend $httpBackend mock}.
+ *
+ * For a higher level of abstraction, please check out the {@link ngResource.$resource
+ * $resource} service.
+ *
+ * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
+ * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
+ * it is important to familiarize yourself with these APIs and the guarantees they provide.
+ *
+ *
+ * ## General usage
+ * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
+ * that is used to generate an HTTP request and returns a {@link ng.$q promise}.
+ *
+ * ```js
+ * // Simple GET request example:
+ * $http({
+ * method: 'GET',
+ * url: '/someUrl'
+ * }).then(function successCallback(response) {
+ * // this callback will be called asynchronously
+ * // when the response is available
+ * }, function errorCallback(response) {
+ * // called asynchronously if an error occurs
+ * // or server returns response with an error status.
+ * });
+ * ```
+ *
+ * The response object has these properties:
+ *
+ * - **data** – `{string|Object}` – The response body transformed with the transform
+ * functions.
+ * - **status** – `{number}` – HTTP status code of the response.
+ * - **headers** – `{function([headerName])}` – Header getter function.
+ * - **config** – `{Object}` – The configuration object that was used to generate the request.
+ * - **statusText** – `{string}` – HTTP status text of the response.
+ *
+ * A response status code between 200 and 299 is considered a success status and will result in
+ * the success callback being called. Any response status code outside of that range is
+ * considered an error status and will result in the error callback being called.
+ * Also, status codes less than -1 are normalized to zero. -1 usually means the request was
+ * aborted, e.g. using a `config.timeout`.
+ * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning
+ * that the outcome (success or error) will be determined by the final response status code.
+ *
+ *
+ * ## Shortcut methods
+ *
+ * Shortcut methods are also available. All shortcut methods require passing in the URL, and
+ * request data must be passed in for POST/PUT requests. An optional config can be passed as the
+ * last argument.
+ *
+ * ```js
+ * $http.get('/someUrl', config).then(successCallback, errorCallback);
+ * $http.post('/someUrl', data, config).then(successCallback, errorCallback);
+ * ```
+ *
+ * Complete list of shortcut methods:
+ *
+ * - {@link ng.$http#get $http.get}
+ * - {@link ng.$http#head $http.head}
+ * - {@link ng.$http#post $http.post}
+ * - {@link ng.$http#put $http.put}
+ * - {@link ng.$http#delete $http.delete}
+ * - {@link ng.$http#jsonp $http.jsonp}
+ * - {@link ng.$http#patch $http.patch}
+ *
+ *
+ * ## Writing Unit Tests that use $http
+ * When unit testing (using {@link ngMock ngMock}), it is necessary to call
+ * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
+ * request using trained responses.
+ *
+ * ```
+ * $httpBackend.expectGET(...);
+ * $http.get(...);
+ * $httpBackend.flush();
+ * ```
+ *
+ * ## Setting HTTP Headers
+ *
+ * The $http service will automatically add certain HTTP headers to all requests. These defaults
+ * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
+ * object, which currently contains this default configuration:
+ *
+ * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
+ * - Accept: application/json, text/plain, \*/\*
+ * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
+ * - `Content-Type: application/json`
+ * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
+ * - `Content-Type: application/json`
+ *
+ * To add or overwrite these defaults, simply add or remove a property from these configuration
+ * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
+ * with the lowercased HTTP method name as the key, e.g.
+ * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
+ *
+ * The defaults can also be set at runtime via the `$http.defaults` object in the same
+ * fashion. For example:
+ *
+ * ```
+ * module.run(function($http) {
+ * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
+ * });
+ * ```
+ *
+ * In addition, you can supply a `headers` property in the config object passed when
+ * calling `$http(config)`, which overrides the defaults without changing them globally.
+ *
+ * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
+ * Use the `headers` property, setting the desired header to `undefined`. For example:
+ *
+ * ```js
+ * var req = {
+ * method: 'POST',
+ * url: 'http://example.com',
+ * headers: {
+ * 'Content-Type': undefined
+ * },
+ * data: { test: 'test' }
+ * }
+ *
+ * $http(req).then(function(){...}, function(){...});
+ * ```
+ *
+ * ## Transforming Requests and Responses
+ *
+ * Both requests and responses can be transformed using transformation functions: `transformRequest`
+ * and `transformResponse`. These properties can be a single function that returns
+ * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
+ * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
+ *
+ *
+ * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
+ * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
+ * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
+ * function will be reflected on the scope and in any templates where the object is data-bound.
+ * To prevent this, transform functions should have no side-effects.
+ * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
+ *
+ *
+ * ### Default Transformations
+ *
+ * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
+ * `defaults.transformResponse` properties. If a request does not provide its own transformations
+ * then these will be applied.
+ *
+ * You can augment or replace the default transformations by modifying these properties by adding to or
+ * replacing the array.
+ *
+ * Angular provides the following default transformations:
+ *
+ * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
+ *
+ * - If the `data` property of the request configuration object contains an object, serialize it
+ * into JSON format.
+ *
+ * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
+ *
+ * - If XSRF prefix is detected, strip it (see Security Considerations section below).
+ * - If JSON response is detected, deserialize it using a JSON parser.
+ *
+ *
+ * ### Overriding the Default Transformations Per Request
+ *
+ * If you wish to override the request/response transformations only for a single request then provide
+ * `transformRequest` and/or `transformResponse` properties on the configuration object passed
+ * into `$http`.
+ *
+ * Note that if you provide these properties on the config object the default transformations will be
+ * overwritten. If you wish to augment the default transformations then you must include them in your
+ * local transformation array.
+ *
+ * The following code demonstrates adding a new response transformation to be run after the default response
+ * transformations have been run.
+ *
+ * ```js
+ * function appendTransform(defaults, transform) {
+ *
+ * // We can't guarantee that the default transformation is an array
+ * defaults = angular.isArray(defaults) ? defaults : [defaults];
+ *
+ * // Append the new transformation to the defaults
+ * return defaults.concat(transform);
+ * }
+ *
+ * $http({
+ * url: '...',
+ * method: 'GET',
+ * transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
+ * return doTransform(value);
+ * })
+ * });
+ * ```
+ *
+ *
+ * ## Caching
+ *
+ * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
+ * set the config.cache value or the default cache value to TRUE or to a cache object (created
+ * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
+ * precedence over the default cache value.
+ *
+ * In order to:
+ * * cache all responses - set the default cache value to TRUE or to a cache object
+ * * cache a specific response - set config.cache value to TRUE or to a cache object
+ *
+ * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
+ * then the default `$cacheFactory("$http")` object is used.
+ *
+ * The default cache value can be set by updating the
+ * {@link ng.$http#defaults `$http.defaults.cache`} property or the
+ * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
+ *
+ * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
+ * the relevant cache object. The next time the same request is made, the response is returned
+ * from the cache without sending a request to the server.
+ *
+ * Take note that:
+ *
+ * * Only GET and JSONP requests are cached.
+ * * The cache key is the request URL including search parameters; headers are not considered.
+ * * Cached responses are returned asynchronously, in the same way as responses from the server.
+ * * If multiple identical requests are made using the same cache, which is not yet populated,
+ * one request will be made to the server and remaining requests will return the same response.
+ * * A cache-control header on the response does not affect if or how responses are cached.
+ *
+ *
+ * ## Interceptors
+ *
+ * Before you start creating interceptors, be sure to understand the
+ * {@link ng.$q $q and deferred/promise APIs}.
+ *
+ * For purposes of global error handling, authentication, or any kind of synchronous or
+ * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
+ * able to intercept requests before they are handed to the server and
+ * responses before they are handed over to the application code that
+ * initiated these requests. The interceptors leverage the {@link ng.$q
+ * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
+ *
+ * The interceptors are service factories that are registered with the `$httpProvider` by
+ * adding them to the `$httpProvider.interceptors` array. The factory is called and
+ * injected with dependencies (if specified) and returns the interceptor.
+ *
+ * There are two kinds of interceptors (and two kinds of rejection interceptors):
+ *
+ * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
+ * modify the `config` object or create a new one. The function needs to return the `config`
+ * object directly, or a promise containing the `config` or a new `config` object.
+ * * `requestError`: interceptor gets called when a previous interceptor threw an error or
+ * resolved with a rejection.
+ * * `response`: interceptors get called with http `response` object. The function is free to
+ * modify the `response` object or create a new one. The function needs to return the `response`
+ * object directly, or as a promise containing the `response` or a new `response` object.
+ * * `responseError`: interceptor gets called when a previous interceptor threw an error or
+ * resolved with a rejection.
+ *
+ *
+ * ```js
+ * // register the interceptor as a service
+ * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
+ * return {
+ * // optional method
+ * 'request': function(config) {
+ * // do something on success
+ * return config;
+ * },
+ *
+ * // optional method
+ * 'requestError': function(rejection) {
+ * // do something on error
+ * if (canRecover(rejection)) {
+ * return responseOrNewPromise
+ * }
+ * return $q.reject(rejection);
+ * },
+ *
+ *
+ *
+ * // optional method
+ * 'response': function(response) {
+ * // do something on success
+ * return response;
+ * },
+ *
+ * // optional method
+ * 'responseError': function(rejection) {
+ * // do something on error
+ * if (canRecover(rejection)) {
+ * return responseOrNewPromise
+ * }
+ * return $q.reject(rejection);
+ * }
+ * };
+ * });
+ *
+ * $httpProvider.interceptors.push('myHttpInterceptor');
+ *
+ *
+ * // alternatively, register the interceptor via an anonymous factory
+ * $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
+ * return {
+ * 'request': function(config) {
+ * // same as above
+ * },
+ *
+ * 'response': function(response) {
+ * // same as above
+ * }
+ * };
+ * });
+ * ```
+ *
+ * ## Security Considerations
+ *
+ * When designing web applications, consider security threats from:
+ *
+ * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
+ * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
+ *
+ * Both server and the client must cooperate in order to eliminate these threats. Angular comes
+ * pre-configured with strategies that address these issues, but for this to work backend server
+ * cooperation is required.
+ *
+ * ### JSON Vulnerability Protection
+ *
+ * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
+ * allows third party website to turn your JSON resource URL into
+ * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
+ * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
+ * Angular will automatically strip the prefix before processing it as JSON.
+ *
+ * For example if your server needs to return:
+ * ```js
+ * ['one','two']
+ * ```
+ *
+ * which is vulnerable to attack, your server can return:
+ * ```js
+ * )]}',
+ * ['one','two']
+ * ```
+ *
+ * Angular will strip the prefix, before processing the JSON.
+ *
+ *
+ * ### Cross Site Request Forgery (XSRF) Protection
+ *
+ * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
+ * which the attacker can trick an authenticated user into unknowingly executing actions on your
+ * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the
+ * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
+ * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the
+ * cookie, your server can be assured that the XHR came from JavaScript running on your domain.
+ * The header will not be set for cross-domain requests.
+ *
+ * To take advantage of this, your server needs to set a token in a JavaScript readable session
+ * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
+ * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
+ * that only JavaScript running on your domain could have sent the request. The token must be
+ * unique for each user and must be verifiable by the server (to prevent the JavaScript from
+ * making up its own tokens). We recommend that the token is a digest of your site's
+ * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))
+ * for added security.
+ *
+ * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
+ * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
+ * or the per-request config object.
+ *
+ * In order to prevent collisions in environments where multiple Angular apps share the
+ * same domain or subdomain, we recommend that each application uses unique cookie name.
+ *
+ * @param {object} config Object describing the request to be made and how it should be
+ * processed. The object has following properties:
+ *
+ * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
+ * - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested;
+ * or an object created by a call to `$sce.trustAsResourceUrl(url)`.
+ * - **params** – `{Object.}` – Map of strings or objects which will be serialized
+ * with the `paramSerializer` and appended as GET parameters.
+ * - **data** – `{string|Object}` – Data to be sent as the request message data.
+ * - **headers** – `{Object}` – Map of strings or functions which return strings representing
+ * HTTP headers to send to the server. If the return value of a function is null, the
+ * header will not be sent. Functions accept a config object as an argument.
+ * - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
+ * To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
+ * The handler will be called in the context of a `$apply` block.
+ * - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
+ * object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
+ * The handler will be called in the context of a `$apply` block.
+ * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
+ * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
+ * - **transformRequest** –
+ * `{function(data, headersGetter)|Array.}` –
+ * transform function or an array of such functions. The transform function takes the http
+ * request body and headers and returns its transformed (typically serialized) version.
+ * See {@link ng.$http#overriding-the-default-transformations-per-request
+ * Overriding the Default Transformations}
+ * - **transformResponse** –
+ * `{function(data, headersGetter, status)|Array.}` –
+ * transform function or an array of such functions. The transform function takes the http
+ * response body, headers and status and returns its transformed (typically deserialized) version.
+ * See {@link ng.$http#overriding-the-default-transformations-per-request
+ * Overriding the Default Transformations}
+ * - **paramSerializer** - `{string|function(Object):string}` - A function used to
+ * prepare the string representation of request parameters (specified as an object).
+ * If specified as string, it is interpreted as function registered with the
+ * {@link $injector $injector}, which means you can create your own serializer
+ * by registering it as a {@link auto.$provide#service service}.
+ * The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
+ * alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
+ * - **cache** – `{boolean|Object}` – A boolean value or object created with
+ * {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
+ * See {@link $http#caching $http Caching} for more information.
+ * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
+ * that should abort the request when resolved.
+ * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
+ * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
+ * for more information.
+ * - **responseType** - `{string}` - see
+ * [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
+ *
+ * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object
+ * when the request succeeds or fails.
+ *
+ *
+ * @property {Array.} pendingRequests Array of config objects for currently pending
+ * requests. This is primarily meant to be used for debugging purposes.
+ *
+ *
+ * @example

- *

- *
- * @description
- *
- * Compiles a string with markup into an interpolation function. This service is used by the
- * HTML {@link ng.$compile $compile} service for data binding. See
- * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
- * interpolation markup.
- *
- *
- * ```js
- * var $interpolate = ...; // injected
- * var exp = $interpolate('Hello {{name | uppercase}}!');
- * expect(exp({name:'Angular'})).toEqual('Hello ANGULAR!');
- * ```
- *
- * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
- * `true`, the interpolation function will return `undefined` unless all embedded expressions
- * evaluate to a value other than `undefined`.
- *
- * ```js
- * var $interpolate = ...; // injected
- * var context = {greeting: 'Hello', name: undefined };
- *
- * // default "forgiving" mode
- * var exp = $interpolate('{{greeting}} {{name}}!');
- * expect(exp(context)).toEqual('Hello !');
- *
- * // "allOrNothing" mode
- * exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
- * expect(exp(context)).toBeUndefined();
- * context.name = 'Angular';
- * expect(exp(context)).toEqual('Hello Angular!');
- * ```
- *
- * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
- *
- * #### Escaped Interpolation
- * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
- * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
- * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
- * or binding.
- *
- * This enables web-servers to prevent script injection attacks and defacing attacks, to some
- * degree, while also enabling code examples to work without relying on the
- * {@link ng.directive:ngNonBindable ngNonBindable} directive.
- *
- * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
- * replacing angle brackets (<, >) with < and > respectively, and replacing all
- * interpolation start/end markers with their escaped counterparts.**
- *
- * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
- * output when the $interpolate service processes the text. So, for HTML elements interpolated
- * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
- * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
- * this is typically useful only when user-data is used in rendering a template from the server, or
- * when otherwise untrusted data is used by a directive.
- *
- *
- *
- *
- *
{{apptitle}}: \{\{ username = "defaced value"; \}\}
- *
- *
{{username}} attempts to inject code which will deface the
- * application, but fails to accomplish their task, because the server has correctly
- * escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
- * characters.
- *
Instead, the result of the attempted script injection is visible, and can be removed
- * from the database by an administrator.
- *
- *
- *
- * @knownIssue
- * It is currently not possible for an interpolated expression to contain the interpolation end
- * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
- * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
- *
- * @knownIssue
- * All directives and components must use the standard `{{` `}}` interpolation symbols
- * in their templates. If you change the application interpolation symbols the {@link $compile}
- * service will attempt to denormalize the standard symbols to the custom symbols.
- * The denormalization process is not clever enough to know not to replace instances of the standard
- * symbols where they would not normally be treated as interpolation symbols. For example in the following
- * code snippet the closing braces of the literal object will get incorrectly denormalized:
- *
- * ```
- *
- * ```
- *
- * See https://github.com/angular/angular.js/pull/14610#issuecomment-219401099 for more information.

+ *
+ * @description
+ *
+ * Compiles a string with markup into an interpolation function. This service is used by the
+ * HTML {@link ng.$compile $compile} service for data binding. See
+ * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
+ * interpolation markup.
+ *
+ *
+ * ```js
+ * var $interpolate = ...; // injected
+ * var exp = $interpolate('Hello {{name | uppercase}}!');
+ * expect(exp({name:'Angular'})).toEqual('Hello ANGULAR!');
+ * ```
+ *
+ * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
+ * `true`, the interpolation function will return `undefined` unless all embedded expressions
+ * evaluate to a value other than `undefined`.
+ *
+ * ```js
+ * var $interpolate = ...; // injected
+ * var context = {greeting: 'Hello', name: undefined };
+ *
+ * // default "forgiving" mode
+ * var exp = $interpolate('{{greeting}} {{name}}!');
+ * expect(exp(context)).toEqual('Hello !');

+ * exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
+ * expect(exp(context)).toBeUndefined();
+ * context.name = 'Angular';
+ * expect(exp(context)).toEqual('Hello Angular!');
+ * ```
+ *
+ * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
+ *
+ * #### Escaped Interpolation
+ * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
+ * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
+ * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
+ * or binding.
+ *
+ * This enables web-servers to prevent script injection attacks and defacing attacks, to some
+ * degree, while also enabling code examples to work without relying on the
+ * {@link ng.directive:ngNonBindable ngNonBindable} directive.
+ *
+ * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
+ * replacing angle brackets (<, >) with < and > respectively, and replacing all
+ * interpolation start/end markers with their escaped counterparts.**
+ *
+ * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
+ * output when the $interpolate service processes the text. So, for HTML elements interpolated
+ * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
+ * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
+ * this is typically useful only when user-data is used in rendering a template from the server, or
+ * when otherwise untrusted data is used by a directive.
+ *
+ *
+ *
+ *
+ *
{{apptitle}}: \{\{ username = "defaced value"; \}\}
+ *
+ *
{{username}} attempts to inject code which will deface the
+ * application, but fails to accomplish their task, because the server has correctly
+ * escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
+ * characters.
+ *
Instead, the result of the attempted script injection is visible, and can be removed
+ * from the database by an administrator.
+ *
+ *
+ *
+ * @knownIssue
+ * It is currently not possible for an interpolated expression to contain the interpolation end
+ * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
+ * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
+ *
+ * @knownIssue
+ * All directives and components must use the standard `{{` `}}` interpolation symbols
+ * in their templates. If you change the application interpolation symbols the {@link $compile}
+ * service will attempt to denormalize the standard symbols to the custom symbols.
+ * The denormalization process is not clever enough to know not to replace instances of the standard
+ * symbols where they would not normally be treated as interpolation symbols. For example in the following
+ * code snippet the closing braces of the literal object will get incorrectly denormalized:
+ *
+ * ```
+ *
+ * ```
+ *
+ * See https://github.com/angular/angular.js/pull/14610#issuecomment-219401099 for more information.

-//
-// As an example, consider the following Angular expression:
-//
-// {}.toString.constructor('alert("evil JS code")')
-//
-// It is important to realize that if you create an expression from a string that contains user provided
-// content then it is possible that your application contains a security vulnerability to an XSS style attack.
-//
-// See https://docs.angularjs.org/guide/security

- // into a string via the toString method.
- // -- MDN, https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Operators/Property_accessors#Property_names
- //
- // So, to ensure that we are checking the same `name` that JavaScript would use, we cast it
- // to a string. It's not always possible. If `name` is an object and its `toString` method is
- // 'broken' (doesn't return a string, isn't a function, etc.), an error will be thrown:
- //
- // TypeError: Cannot convert object to primitive value
- //
- // For performance reasons, we don't catch this error here and allow it to propagate up the call
- // stack. Note that you'll get the same error in JavaScript if you try to access a property using
- // such a 'broken' object as a key.

-/**
- * @ngdoc service
- * @name $q
- * @requires $rootScope
- *
- * @description
- * A service that helps you run functions asynchronously, and use their return values (or exceptions)
- * when they are done processing.
- *
- * This is a [Promises/A+](https://promisesaplus.com/)-compliant implementation of promises/deferred
- * objects inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
- *
- * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
- * implementations, and the other which resembles ES6 (ES2015) promises to some degree.
- *
- * # $q constructor
- *
- * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
- * function as the first argument. This is similar to the native Promise implementation from ES6,
- * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
- *
- * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are
- * available yet.
- *
- * It can be used like so:
- *
- * ```js
- * // for the purpose of this example let's assume that variables `$q` and `okToGreet`
- * // are available in the current lexical scope (they could have been injected or passed in).
- *
- * function asyncGreet(name) {
- * // perform some asynchronous operation, resolve or reject the promise when appropriate.
- * return $q(function(resolve, reject) {
- * setTimeout(function() {
- * if (okToGreet(name)) {
- * resolve('Hello, ' + name + '!');
- * } else {
- * reject('Greeting ' + name + ' is not allowed.');
- * }
- * }, 1000);
- * });
- * }
- *
- * var promise = asyncGreet('Robin Hood');
- * promise.then(function(greeting) {
- * alert('Success: ' + greeting);
- * }, function(reason) {
- * alert('Failed: ' + reason);
- * });
- * ```
- *
- * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
- *
- * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.
- *
- * However, the more traditional CommonJS-style usage is still available, and documented below.
- *
- * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
- * interface for interacting with an object that represents the result of an action that is
- * performed asynchronously, and may or may not be finished at any given point in time.
- *
- * From the perspective of dealing with error handling, deferred and promise APIs are to
- * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
- *
- * ```js
- * // for the purpose of this example let's assume that variables `$q` and `okToGreet`
- * // are available in the current lexical scope (they could have been injected or passed in).
- *
- * function asyncGreet(name) {
- * var deferred = $q.defer();
- *
- * setTimeout(function() {
- * deferred.notify('About to greet ' + name + '.');
- *
- * if (okToGreet(name)) {
- * deferred.resolve('Hello, ' + name + '!');
- * } else {
- * deferred.reject('Greeting ' + name + ' is not allowed.');
- * }
- * }, 1000);
- *
- * return deferred.promise;
- * }
- *
- * var promise = asyncGreet('Robin Hood');
- * promise.then(function(greeting) {
- * alert('Success: ' + greeting);
- * }, function(reason) {
- * alert('Failed: ' + reason);
- * }, function(update) {
- * alert('Got notification: ' + update);
- * });
- * ```
- *
- * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
- * comes in the way of guarantees that promise and deferred APIs make, see
- * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
- *
- * Additionally the promise api allows for composition that is very hard to do with the
- * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
- * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
- * section on serial or parallel joining of promises.
- *
- * # The Deferred API
- *
- * A new instance of deferred is constructed by calling `$q.defer()`.
- *
- * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
- * that can be used for signaling the successful or unsuccessful completion, as well as the status
- * of the task.
- *
- * **Methods**
- *
- * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
- * constructed via `$q.reject`, the promise will be rejected instead.
- * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
- * resolving it with a rejection constructed via `$q.reject`.
- * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
- * multiple times before the promise is either resolved or rejected.
- *
- * **Properties**
- *
- * - promise – `{Promise}` – promise object associated with this deferred.
- *
- *
- * # The Promise API
- *
- * A new promise instance is created when a deferred instance is created and can be retrieved by
- * calling `deferred.promise`.
- *
- * The purpose of the promise object is to allow for interested parties to get access to the result
- * of the deferred task when it completes.
- *
- * **Methods**
- *
- * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or
- * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
- * as soon as the result is available. The callbacks are called with a single argument: the result
- * or rejection reason. Additionally, the notify callback may be called zero or more times to
- * provide a progress indication, before the promise is resolved or rejected.
- *
- * This method *returns a new promise* which is resolved or rejected via the return value of the
- * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
- * with the value which is resolved in that promise using
- * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
- * It also notifies via the return value of the `notifyCallback` method. The promise cannot be
- * resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback
- * arguments are optional.
- *
- * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
- *
- * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
- * but to do so without modifying the final value. This is useful to release resources or do some
- * clean-up that needs to be done whether the promise was rejected or resolved. See the [full
- * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
- * more information.
- *
- * # Chaining promises
- *
- * Because calling the `then` method of a promise returns a new derived promise, it is easily
- * possible to create a chain of promises:
- *
- * ```js
- * promiseB = promiseA.then(function(result) {
- * return result + 1;
- * });
- *
- * // promiseB will be resolved immediately after promiseA is resolved and its value
- * // will be the result of promiseA incremented by 1
- * ```
- *
- * It is possible to create chains of any length and since a promise can be resolved with another
- * promise (which will defer its resolution further), it is possible to pause/defer resolution of
- * the promises at any point in the chain. This makes it possible to implement powerful APIs like
- * $http's response interceptors.
- *
- *
- * # Differences between Kris Kowal's Q and $q
- *
- * There are two main differences:
- *
- * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
- * mechanism in angular, which means faster propagation of resolution or rejection into your
- * models and avoiding unnecessary browser repaints, which would result in flickering UI.
- * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
- * all the important functionality needed for common async tasks.
- *
- * # Testing
- *
- * ```js
- * it('should simulate promise', inject(function($q, $rootScope) {
- * var deferred = $q.defer();
- * var promise = deferred.promise;
- * var resolvedValue;
- *
- * promise.then(function(value) { resolvedValue = value; });
- * expect(resolvedValue).toBeUndefined();
- *
- * // Simulate resolving of promise
- * deferred.resolve(123);
- * // Note that the 'then' function does not get called synchronously.
- * // This is because we want the promise API to always be async, whether or not
- * // it got called synchronously or asynchronously.
- * expect(resolvedValue).toBeUndefined();
- *
- * // Propagate promise resolution to 'then' functions using $apply().
- * $rootScope.$apply();
- * expect(resolvedValue).toEqual(123);
- * }));
- * ```
- *
- * @param {function(function, function)} resolver Function which is responsible for resolving or
- * rejecting the newly created promise. The first parameter is a function which resolves the
- * promise, the second parameter is a function which rejects the promise.
- *
- * @returns {Promise} The newly created promise.

- * @ngdoc method

- * @kind function
+ * @ngdoc service
+ * @name $q
+ * @requires $rootScope
*
* @description
- * Creates a promise that is resolved as rejected with the specified `reason`. This api should be
- * used to forward rejection in a chain of promises. If you are dealing with the last promise in
- * a promise chain, you don't need to worry about it.
+ * A service that helps you run functions asynchronously, and use their return values (or exceptions)
+ * when they are done processing.
+ *
+ * This is a [Promises/A+](https://promisesaplus.com/)-compliant implementation of promises/deferred
+ * objects inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
+ *
+ * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
+ * implementations, and the other which resembles ES6 (ES2015) promises to some degree.
*
- * When comparing deferreds/promises to the familiar behavior of try/catch/throw, think of
- * `reject` as the `throw` keyword in JavaScript. This also means that if you "catch" an error via
- * a promise error callback and you want to forward the error to the promise derived from the
- * current promise, you have to "rethrow" the error by returning a rejection constructed via
- * `reject`.
+ * # $q constructor
+ *
+ * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
+ * function as the first argument. This is similar to the native Promise implementation from ES6,
+ * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
+ *
+ * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are
+ * available yet.
+ *
+ * It can be used like so:
*
* ```js
- * promiseB = promiseA.then(function(result) {
- * // success: do something and resolve promiseB
- * // with the old or a new result
- * return result;
+ * // for the purpose of this example let's assume that variables `$q` and `okToGreet`
+ * // are available in the current lexical scope (they could have been injected or passed in).
+ *
+ * function asyncGreet(name) {
+ * // perform some asynchronous operation, resolve or reject the promise when appropriate.
+ * return $q(function(resolve, reject) {
+ * setTimeout(function() {
+ * if (okToGreet(name)) {
+ * resolve('Hello, ' + name + '!');
+ * } else {
+ * reject('Greeting ' + name + ' is not allowed.');
+ * }
+ * }, 1000);
+ * });
+ * }
+ *
+ * var promise = asyncGreet('Robin Hood');
+ * promise.then(function(greeting) {
+ * alert('Success: ' + greeting);
* }, function(reason) {
- * // error: handle the error if possible and
- * // resolve promiseB with newPromiseOrValue,
- * // otherwise forward the rejection to promiseB
- * if (canHandle(reason)) {
- * // handle the error and recover
- * return newPromiseOrValue;
- * }
- * return $q.reject(reason);
+ * alert('Failed: ' + reason);
* });
* ```
*
- * @param {*} reason Constant, message, exception or an object representing the rejection reason.
- * @returns {Promise} Returns a promise that was already resolved as rejected with the `reason`.

- * @description
- * Alias of {@link ng.$q#when when} to maintain naming consistency with ES6.
+ * However, the more traditional CommonJS-style usage is still available, and documented below.
+ *
+ * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
+ * interface for interacting with an object that represents the result of an action that is
+ * performed asynchronously, and may or may not be finished at any given point in time.
+ *
+ * From the perspective of dealing with error handling, deferred and promise APIs are to
+ * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
+ *
+ * ```js
+ * // for the purpose of this example let's assume that variables `$q` and `okToGreet`
+ * // are available in the current lexical scope (they could have been injected or passed in).
+ *
+ * function asyncGreet(name) {
+ * var deferred = $q.defer();
+ *
+ * setTimeout(function() {
+ * deferred.notify('About to greet ' + name + '.');
+ *
+ * if (okToGreet(name)) {
+ * deferred.resolve('Hello, ' + name + '!');
+ * } else {
+ * deferred.reject('Greeting ' + name + ' is not allowed.');
+ * }
+ * }, 1000);
+ *
+ * return deferred.promise;
+ * }
+ *
+ * var promise = asyncGreet('Robin Hood');
+ * promise.then(function(greeting) {
+ * alert('Success: ' + greeting);
+ * }, function(reason) {
+ * alert('Failed: ' + reason);
+ * }, function(update) {
+ * alert('Got notification: ' + update);
+ * });
+ * ```
+ *
+ * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
+ * comes in the way of guarantees that promise and deferred APIs make, see
+ * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
+ *
+ * Additionally the promise api allows for composition that is very hard to do with the
+ * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
+ * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
+ * section on serial or parallel joining of promises.
+ *
+ * # The Deferred API
+ *
+ * A new instance of deferred is constructed by calling `$q.defer()`.
+ *
+ * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
+ * that can be used for signaling the successful or unsuccessful completion, as well as the status
+ * of the task.
+ *
+ * **Methods**
+ *
+ * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
+ * constructed via `$q.reject`, the promise will be rejected instead.
+ * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
+ * resolving it with a rejection constructed via `$q.reject`.
+ * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
+ * multiple times before the promise is either resolved or rejected.
+ *
+ * **Properties**
+ *
+ * - promise – `{Promise}` – promise object associated with this deferred.
+ *
+ *
+ * # The Promise API
+ *
+ * A new promise instance is created when a deferred instance is created and can be retrieved by
+ * calling `deferred.promise`.
+ *
+ * The purpose of the promise object is to allow for interested parties to get access to the result
+ * of the deferred task when it completes.
+ *
+ * **Methods**
+ *
+ * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or
+ * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
+ * as soon as the result is available. The callbacks are called with a single argument: the result
+ * or rejection reason. Additionally, the notify callback may be called zero or more times to
+ * provide a progress indication, before the promise is resolved or rejected.
+ *
+ * This method *returns a new promise* which is resolved or rejected via the return value of the
+ * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
+ * with the value which is resolved in that promise using
+ * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
+ * It also notifies via the return value of the `notifyCallback` method. The promise cannot be
+ * resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback
+ * arguments are optional.
*
- * @param {*} value Value or a promise
- * @param {Function=} successCallback
- * @param {Function=} errorCallback
- * @param {Function=} progressCallback
- * @returns {Promise} Returns a promise of the passed value or promise
+ * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
+ *
+ * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
+ * but to do so without modifying the final value. This is useful to release resources or do some
+ * clean-up that needs to be done whether the promise was rejected or resolved. See the [full
+ * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
+ * more information.
+ *
+ * # Chaining promises
+ *
+ * Because calling the `then` method of a promise returns a new derived promise, it is easily
+ * possible to create a chain of promises:
+ *
+ * ```js
+ * promiseB = promiseA.then(function(result) {
+ * return result + 1;
+ * });
+ *
+ * // promiseB will be resolved immediately after promiseA is resolved and its value
+ * // will be the result of promiseA incremented by 1
+ * ```
+ *
+ * It is possible to create chains of any length and since a promise can be resolved with another
+ * promise (which will defer its resolution further), it is possible to pause/defer resolution of
+ * the promises at any point in the chain. This makes it possible to implement powerful APIs like
+ * $http's response interceptors.
+ *
+ *
+ * # Differences between Kris Kowal's Q and $q
+ *
+ * There are two main differences:
+ *
+ * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
+ * mechanism in angular, which means faster propagation of resolution or rejection into your
+ * models and avoiding unnecessary browser repaints, which would result in flickering UI.
+ * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
+ * all the important functionality needed for common async tasks.
+ *
+ * # Testing
+ *
+ * ```js
+ * it('should simulate promise', inject(function($q, $rootScope) {
+ * var deferred = $q.defer();
+ * var promise = deferred.promise;
+ * var resolvedValue;
+ *
+ * promise.then(function(value) { resolvedValue = value; });
+ * expect(resolvedValue).toBeUndefined();
+ *
+ * // Simulate resolving of promise
+ * deferred.resolve(123);
+ * // Note that the 'then' function does not get called synchronously.
+ * // This is because we want the promise API to always be async, whether or not
+ * // it got called synchronously or asynchronously.
+ * expect(resolvedValue).toBeUndefined();
+ *
+ * // Propagate promise resolution to 'then' functions using $apply().
+ * $rootScope.$apply();
+ * expect(resolvedValue).toEqual(123);
+ * }));
+ * ```
+ *
+ * @param {function(function, function)} resolver Function which is responsible for resolving or
+ * rejecting the newly created promise. The first parameter is a function which resolves the
+ * promise, the second parameter is a function which rejects the promise.
+ *
+ * @returns {Promise} The newly created promise.

- * DESIGN NOTES
- *
- * The design decisions behind the scope are heavily favored for speed and memory consumption.
- *
- * The typical use of scope is to watch the expressions, which most of the time return the same
- * value as last time so we optimize the operation.
- *
- * Closures construction is expensive in terms of speed as well as memory:
- * - No closures, instead use prototypical inheritance for API
- * - Internal state needs to be stored on scope directly, which means that private state is
- * exposed as $$____ properties
- *
- * Loop operations are optimized by using while(count--) { ... }
- * - This means that in order to keep the same order of execution as addition we have to add
- * items to the array at the beginning (unshift) instead of at the end (push)
- *
- * Child scopes are created and removed often
- * - Using an array would be slow since inserts in the middle are expensive; so we use linked lists
- *
- * There are fewer watches than observers. This is why you don't want the observer to be implemented
- * in the same way as watch. Watch requires return of the initialization function which is expensive
- * to construct.

* @description
- * A root scope can be retrieved using the {@link ng.$rootScope $rootScope} key from the
- * {@link auto.$injector $injector}. Child scopes are created using the
- * {@link ng.$rootScope.Scope#$new $new()} method. (Most scopes are created automatically when
- * compiled HTML template is executed.) See also the {@link guide/scope Scopes guide} for
- * an in-depth introduction and usage examples.
+ * Creates a promise that is resolved as rejected with the specified `reason`. This api should be
+ * used to forward rejection in a chain of promises. If you are dealing with the last promise in
+ * a promise chain, you don't need to worry about it.
*
+ * When comparing deferreds/promises to the familiar behavior of try/catch/throw, think of
+ * `reject` as the `throw` keyword in JavaScript. This also means that if you "catch" an error via
+ * a promise error callback and you want to forward the error to the promise derived from the
+ * current promise, you have to "rethrow" the error by returning a rejection constructed via
+ * `reject`.
*
- * # Inheritance
- * A scope can inherit from a parent scope, as in this example:
* ```js
- var parent = $rootScope;
- var child = parent.$new();
-
- parent.salutation = "Hello";
- expect(child.salutation).toEqual('Hello');
-
- child.salutation = "Welcome";
- expect(child.salutation).toEqual('Welcome');
- expect(parent.salutation).toEqual('Hello');
+ * promiseB = promiseA.then(function(result) {
+ * // success: do something and resolve promiseB
+ * // with the old or a new result
+ * return result;
+ * }, function(reason) {
+ * // error: handle the error if possible and
+ * // resolve promiseB with newPromiseOrValue,
+ * // otherwise forward the rejection to promiseB
+ * if (canHandle(reason)) {
+ * // handle the error and recover
+ * return newPromiseOrValue;
+ * }
+ * return $q.reject(reason);
+ * });
* ```
*
- * When interacting with `Scope` in tests, additional helper methods are available on the

- * @description
- * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
- *
- * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
- * $digest()} and should return the value that will be watched. (`watchExpression` should not change
- * its value when executed multiple times with the same input because it may be executed multiple
- * times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
- * [idempotent](http://en.wikipedia.org/wiki/Idempotence).)
- * - The `listener` is called only when the value from the current `watchExpression` and the
- * previous call to `watchExpression` are not equal (with the exception of the initial run,
- * see below). Inequality is determined according to reference inequality,
- * [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
- * via the `!==` Javascript operator, unless `objectEquality == true`
- * (see next point)
- * - When `objectEquality == true`, inequality of the `watchExpression` is determined
- * according to the {@link angular.equals} function. To save the value of the object for
- * later comparison, the {@link angular.copy} function is used. This therefore means that
- * watching complex objects will have adverse memory and performance implications.
- * - This should not be used to watch for changes in objects that are
- * or contain [File](https://developer.mozilla.org/docs/Web/API/File) objects due to limitations with {@link angular.copy `angular.copy`}.
- * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
- * This is achieved by rerunning the watchers until no changes are detected. The rerun
- * iteration limit is 10 to prevent an infinite loop deadlock.
- *
- *
- * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
- * you can register a `watchExpression` function with no `listener`. (Be prepared for
- * multiple calls to your `watchExpression` because it will execute multiple times in a
- * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
- *
- * After a watcher is registered with the scope, the `listener` fn is called asynchronously
- * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
- * watcher. In rare cases, this is undesirable because the listener is called when the result
- * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
- * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
- * listener was called due to initialization.
- *
- *
- *
- * # Example
- * ```js
- // let's assume that scope was dependency injected as the $rootScope
- var scope = $rootScope;
- scope.name = 'misko';

+ * DESIGN NOTES
+ *
+ * The design decisions behind the scope are heavily favored for speed and memory consumption.
+ *
+ * The typical use of scope is to watch the expressions, which most of the time return the same
+ * value as last time so we optimize the operation.
+ *
+ * Closures construction is expensive in terms of speed as well as memory:
+ * - No closures, instead use prototypical inheritance for API
+ * - Internal state needs to be stored on scope directly, which means that private state is
+ * exposed as $$____ properties
+ *
+ * Loop operations are optimized by using while(count--) { ... }
+ * - This means that in order to keep the same order of execution as addition we have to add
+ * items to the array at the beginning (unshift) instead of at the end (push)
+ *
+ * Child scopes are created and removed often
+ * - Using an array would be slow since inserts in the middle are expensive; so we use linked lists
+ *
+ * There are fewer watches than observers. This is why you don't want the observer to be implemented
+ * in the same way as watch. Watch requires return of the initialization function which is expensive
+ * to construct.

- * the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}
- * until no more listeners are firing. This means that it is possible to get into an infinite
- * loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
- * iterations exceeds 10.
- *
- * Usually, you don't call `$digest()` directly in
- * {@link ng.directive:ngController controllers} or in
- * {@link ng.$compileProvider#directive directives}.
- * Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within

- *
- * If you want to be notified whenever `$digest()` is called,
- * you can register a `watchExpression` function with
- * {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.

- * In unit tests, you may need to call `$digest()` to simulate the scope life cycle.

+ * @ngdoc method
+ * @name $rootScope.Scope#$watch
+ * @kind function
+ *
+ * @description
+ * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
+ *
+ * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
+ * $digest()} and should return the value that will be watched. (`watchExpression` should not change
+ * its value when executed multiple times with the same input because it may be executed multiple
+ * times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
+ * [idempotent](http://en.wikipedia.org/wiki/Idempotence).)
+ * - The `listener` is called only when the value from the current `watchExpression` and the
+ * previous call to `watchExpression` are not equal (with the exception of the initial run,
+ * see below). Inequality is determined according to reference inequality,
+ * [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
+ * via the `!==` Javascript operator, unless `objectEquality == true`
+ * (see next point)
+ * - When `objectEquality == true`, inequality of the `watchExpression` is determined
+ * according to the {@link angular.equals} function. To save the value of the object for
+ * later comparison, the {@link angular.copy} function is used. This therefore means that
+ * watching complex objects will have adverse memory and performance implications.
+ * - This should not be used to watch for changes in objects that are
+ * or contain [File](https://developer.mozilla.org/docs/Web/API/File) objects due to limitations with {@link angular.copy `angular.copy`}.
+ * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
+ * This is achieved by rerunning the watchers until no changes are detected. The rerun
+ * iteration limit is 10 to prevent an infinite loop deadlock.
+ *
+ *
+ * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
+ * you can register a `watchExpression` function with no `listener`. (Be prepared for
+ * multiple calls to your `watchExpression` because it will execute multiple times in a
+ * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
+ *
+ * After a watcher is registered with the scope, the `listener` fn is called asynchronously
+ * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
+ * watcher. In rare cases, this is undesirable because the listener is called when the result
+ * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
+ * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
+ * listener was called due to initialization.
+ *
+ *
+ *
+ * # Example
+ * ```js
+ // let's assume that scope was dependency injected as the $rootScope
+ var scope = $rootScope;
+ scope.name = 'misko';
+ scope.counter = 0;
+ expect(scope.counter).toEqual(0);
+ scope.$watch('name', function(newValue, oldValue) {

+ });
+ expect(scope.counter).toEqual(0);
+ scope.$digest();
+ // the listener is always called during the first $digest loop after it was registered
+ expect(scope.counter).toEqual(1);
+ scope.$digest();
+ // but now it will not be called unless the value changes
+ expect(scope.counter).toEqual(1);
+ scope.name = 'adam';
+ scope.$digest();
+ expect(scope.counter).toEqual(2);
+ // Using a function as a watchExpression
+ var food;
+ scope.foodCounter = 0;
+ expect(scope.foodCounter).toEqual(0);
+ scope.$watch(
+ // This function returns the value being watched. It is called for each turn of the $digest loop
+ function() { return food; },
+ // This is the change listener, called when the value returned from the above function changes
+ function(newValue, oldValue) {
+ if ( newValue !== oldValue ) {
+ // Only increment the counter if the value changed
+ scope.foodCounter = scope.foodCounter + 1;
+ }
+ }
+ );
+ // No digest has been run so the counter will be zero
+ expect(scope.foodCounter).toEqual(0);
+ // Run the digest but since food has not changed count will still be zero
+ scope.$digest();
+ expect(scope.foodCounter).toEqual(0);
+ // Update food and run digest. Now the counter will increment

+ * @kind function
+ *
+ * @description
+ * Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and
+ * its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change
+ * the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}
+ * until no more listeners are firing. This means that it is possible to get into an infinite
+ * loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
+ * iterations exceeds 10.
+ *
+ * Usually, you don't call `$digest()` directly in
+ * {@link ng.directive:ngController controllers} or in
+ * {@link ng.$compileProvider#directive directives}.
+ * Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within
+ * a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`.
+ *
+ * If you want to be notified whenever `$digest()` is called,
+ * you can register a `watchExpression` function with
+ * {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.
+ *
+ * In unit tests, you may need to call `$digest()` to simulate the scope life cycle.
+ *
+ * # Example
+ * ```js
+ var scope = ...;
+ scope.name = 'misko';
+ scope.counter = 0;
+ expect(scope.counter).toEqual(0);
+ scope.$watch('name', function(newValue, oldValue) {
+ scope.counter = scope.counter + 1;

+ scope.$digest();
+ // the listener is always called during the first $digest loop after it was registered
+ expect(scope.counter).toEqual(1);
+ scope.$digest();
+ // but now it will not be called unless the value changes
+ expect(scope.counter).toEqual(1);

- * @description
- *
- * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict
- * Contextual Escaping (SCE)} services to AngularJS.
- *
- * For an overview of this service and the functionnality it provides in AngularJS, see the main
- * page for {@link ng.$sce SCE}. The current page is targeted for developers who need to alter how
- * SCE works in their application, which shouldn't be needed in most cases.
- *
- *
- * AngularJS strongly relies on contextual escaping for the security of bindings: disabling or
- * modifying this might cause cross site scripting (XSS) vulnerabilities. For libraries owners,
- * changes to this service will also influence users, so be extra careful and document your changes.
- *
- *
- * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
- * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS. This is
- * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to
- * override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things
- * work because `$sce` delegates to `$sceDelegate` for these operations.
- *
- * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
- *
- * The default instance of `$sceDelegate` should work out of the box with little pain. While you
- * can override it completely to change the behavior of `$sce`, the common case would
- * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting
- * your own whitelists and blacklists for trusting URLs used for loading AngularJS resources such as
- * templates. Refer {@link ng.$sceDelegateProvider#resourceUrlWhitelist
- * $sceDelegateProvider.resourceUrlWhitelist} and {@link
- * ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist}

- * @ngdoc service
- * @name $sce
- * @kind function
- *
- * @description
- *
- * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
- *
- * # Strict Contextual Escaping
- *
- * Strict Contextual Escaping (SCE) is a mode in which AngularJS constrains bindings to only render
- * trusted values. Its goal is to assist in writing code in a way that (a) is secure by default, and
- * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
- *
- * ## Overview
- *
- * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in
- * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically
- * run security checks on them (sanitizations, whitelists, depending on context), or throw when it
- * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML
- * can be sanitized, but template URLs cannot, for instance.
- *
- * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML:
- * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it
- * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and
- * render the input as-is, you will need to mark it as trusted for that context before attempting
- * to bind it.
- *
- * As of version 1.2, AngularJS ships with SCE enabled by default.
- *
- * ## In practice
- *
- * Here's an example of a binding in a privileged context:
- *
- * ```
- *
- * ```
- *
- * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE
- * disabled, this application allows the user to render arbitrary HTML into the DIV, which would
- * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog
- * articles, etc. via bindings. (HTML is just one example of a context where rendering user
- * controlled input creates security vulnerabilities.)
- *
- * For the case of HTML, you might use a library, either on the client side, or on the server side,
- * to sanitize unsafe HTML before binding to the value and rendering it in the document.
- *
- * How would you ensure that every place that used these types of bindings was bound to a value that
- * was sanitized by your library (or returned as safe for rendering by your server?) How can you
- * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
- * properties/fields and forgot to update the binding to the sanitized value?
- *
- * To be secure by default, AngularJS makes sure bindings go through that sanitization, or
- * any similar validation process, unless there's a good reason to trust the given value in this
- * context. That trust is formalized with a function call. This means that as a developer, you
- * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues,
- * you just need to ensure the values you mark as trusted indeed are safe - because they were
- * received from your server, sanitized by your library, etc. You can organize your codebase to
- * help with this - perhaps allowing only the files in a specific directory to do this.
- * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then
- * becomes a more manageable task.
- *
- * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
- * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
- * build the trusted versions of your values.
- *
- * ## How does it work?
- *
- * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
- * $sce.getTrusted(context, value)} rather than to the value directly. Think of this function as
- * a way to enforce the required security context in your data sink. Directives use {@link
- * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs
- * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also,
- * when binding without directives, AngularJS will understand the context of your bindings
- * automatically.
- *
- * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
- * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly
- * simplified):
- *
- * ```
- * var ngBindHtmlDirective = ['$sce', function($sce) {
- * return function(scope, element, attr) {
- * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
- * element.html(value || '');
- * });
- * };
- * }];
- * ```
- *
- * ## Impact on loading templates
- *
- * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
- * `templateUrl`'s specified by {@link guide/directive directives}.
- *
- * By default, Angular only loads templates from the same domain and protocol as the application
- * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl
- * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or
- * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
- * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
- *
- * *Please note*:
- * The browser's
- * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
- * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
- * policy apply in addition to this and may further restrict whether the template is successfully
- * loaded. This means that without the right CORS policy, loading templates from a different domain
- * won't work on all browsers. Also, loading templates from `file://` URL does not work on some
- * browsers.
- *
- * ## This feels like too much overhead
- *
- * It's important to remember that SCE only applies to interpolation expressions.
- *
- * If your expressions are constant literals, they're automatically trusted and you don't need to
- * call `$sce.trustAs` on them (e.g.
- * `
`) just works. The `$sceDelegate` will
- * also use the `$sanitize` service if it is available when binding untrusted values to
- * `$sce.HTML` context. AngularJS provides an implementation in `angular-sanitize.js`, and if you
- * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in
- * your application.
- *
- * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
- * templates in `ng-include` from your application's domain without having to even know about SCE.
- * It blocks loading templates from other domains or loading templates over http from an https
- * served document. You can change these by setting your own custom {@link
- * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
- * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
- *
- * This significantly reduces the overhead. It is far easier to pay the small overhead and have an
- * application that's secure and can be audited to verify that with much more ease than bolting
- * security onto an application later.
- *
- *
- *
- *
- *
- *
User comments
- * By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when
- * $sanitize is available. If $sanitize isn't available, this results in an error instead of an
- * exploit.
- *
- *
- * {{userComment.name}} :
- *
- *
- *
- *
- *
- *
- * angular.module('mySceApp', ['ngSanitize'])
- * .controller('AppController', ['$http', '$templateCache', '$sce',
- * function AppController($http, $templateCache, $sce) {
- * var self = this;
- * $http.get('test_data.json', {cache: $templateCache}).then(function(response) {
- * self.userComments = response.data;
- * });
- * self.explicitlyTrustedHtml = $sce.trustAsHtml(
- * 'Hover over this text. ');
- * }]);
- *
- *
- *
- * [
- * { "name": "Alice",
- * "htmlComment":
- * "Is anyone reading this? "
- * },
- * { "name": "Bob",
- * "htmlComment": "Yes! Am I the only other one?"
- * }
- * ]
- *
- *
- *
- * describe('SCE doc demo', function() {
- * it('should sanitize untrusted values', function() {
- * expect(element.all(by.css('.htmlComment')).first().getAttribute('innerHTML'))
- * .toBe('Is anyone reading this? ');
- * });
- *
- * it('should NOT sanitize explicitly trusted values', function() {
- * expect(element(by.id('explicitlyTrustedHtml')).getAttribute('innerHTML')).toBe(
- * 'Hover over this text. ');
- * });
- * });
- *
- *
- *
- *
- *
- * ## Can I disable SCE completely?
- *
- * Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits
- * for little coding overhead. It will be much harder to take an SCE disabled application and
- * either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE
- * for cases where you have a lot of existing code that was written before SCE was introduced and
- * you're migrating them a module at a time. Also do note that this is an app-wide setting, so if
- * you are writing a library, you will cause security bugs applications using it.
- *
- * That said, here's how you can completely disable SCE:
- *
- * ```
- * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
- * // Completely disable SCE. For demonstration purposes only!
- * // Do not use in new projects or libraries.
- * $sceProvider.enabled(false);
- * });
- * ```

- /* Design notes on the default implementation for SCE.
- *
- * The API contract for the SCE delegate
- * -------------------------------------
- * The SCE delegate object must provide the following 3 methods:
- *
- * - trustAs(contextEnum, value)
- * This method is used to tell the SCE service that the provided value is OK to use in the
- * contexts specified by contextEnum. It must return an object that will be accepted by
- * getTrusted() for a compatible contextEnum and return this value.
- *
- * - valueOf(value)
- * For values that were not produced by trustAs(), return them as is. For values that were
- * produced by trustAs(), return the corresponding input value to trustAs. Basically, if
- * trustAs is wrapping the given values into some type, this operation unwraps it when given
- * such a value.
- *
- * - getTrusted(contextEnum, value)
- * This function should return the a value that is safe to use in the context specified by
- * contextEnum or throw and exception otherwise.
- *
- * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
- * opaque or wrapped in some holder object. That happens to be an implementation detail. For
- * instance, an implementation could maintain a registry of all trusted objects by context. In
- * such a case, trustAs() would return the same object that was passed in. getTrusted() would
- * return the same object passed in if it was found in the registry under a compatible context or
- * throw an exception otherwise. An implementation might only wrap values some of the time based
- * on some criteria. getTrusted() might return a value and not throw an exception for special
- * constants or objects even if not wrapped. All such implementations fulfill this contract.
- *
- *
- * A note on the inheritance model for SCE contexts
- * ------------------------------------------------
- * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This
- * is purely an implementation details.
- *
- * The contract is simply this:
- *
- * getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
- * will also succeed.
- *
- * Inheritance happens to capture this in a natural way. In some future, we may not use
- * inheritance anymore. That is OK because no code outside of sce.js and sceSpecs.js would need to
- * be aware of this detail.

+ * AngularJS strongly relies on contextual escaping for the security of bindings: disabling or
+ * modifying this might cause cross site scripting (XSS) vulnerabilities. For libraries owners,
+ * changes to this service will also influence users, so be extra careful and document your changes.
+ *
+ *
+ * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of

+ * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to
+ * override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things
+ * work because `$sce` delegates to `$sceDelegate` for these operations.
+ *
+ * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
+ *
+ * The default instance of `$sceDelegate` should work out of the box with little pain. While you
+ * can override it completely to change the behavior of `$sce`, the common case would
+ * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting

- *
- * Implementation Notes for non-IE browsers
- * ----------------------------------------
- * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
- * results both in the normalizing and parsing of the URL. Normalizing means that a relative
- * URL will be resolved into an absolute URL in the context of the application document.
- * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
- * properties are all populated to reflect the normalized URL. This approach has wide
- * compatibility - Safari 1+, Mozilla 1+ etc. See
- * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
- *
- * Implementation Notes for IE
- * ---------------------------
- * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
- * browsers. However, the parsed components will not be set if the URL assigned did not specify
- * them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We
- * work around that by performing the parsing in a 2nd step by taking a previously normalized
- * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the
- * properties such as protocol, hostname, port, etc.

+ *
+ * @description
+ *
+ * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
+ *
+ * # Strict Contextual Escaping
+ *
+ * Strict Contextual Escaping (SCE) is a mode in which AngularJS constrains bindings to only render
+ * trusted values. Its goal is to assist in writing code in a way that (a) is secure by default, and
+ * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
+ *
+ * ## Overview
+ *
+ * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in
+ * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically
+ * run security checks on them (sanitizations, whitelists, depending on context), or throw when it
+ * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML
+ * can be sanitized, but template URLs cannot, for instance.
+ *
+ * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML:
+ * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it
+ * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and
+ * render the input as-is, you will need to mark it as trusted for that context before attempting
+ * to bind it.
+ *
+ * As of version 1.2, AngularJS ships with SCE enabled by default.
+ *
+ * ## In practice
+ *
+ * Here's an example of a binding in a privileged context:
+ *
+ * ```
+ *
+ * ```
+ *
+ * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE
+ * disabled, this application allows the user to render arbitrary HTML into the DIV, which would
+ * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog
+ * articles, etc. via bindings. (HTML is just one example of a context where rendering user
+ * controlled input creates security vulnerabilities.)
+ *
+ * For the case of HTML, you might use a library, either on the client side, or on the server side,
+ * to sanitize unsafe HTML before binding to the value and rendering it in the document.
+ *
+ * How would you ensure that every place that used these types of bindings was bound to a value that
+ * was sanitized by your library (or returned as safe for rendering by your server?) How can you
+ * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
+ * properties/fields and forgot to update the binding to the sanitized value?
+ *
+ * To be secure by default, AngularJS makes sure bindings go through that sanitization, or
+ * any similar validation process, unless there's a good reason to trust the given value in this
+ * context. That trust is formalized with a function call. This means that as a developer, you
+ * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues,
+ * you just need to ensure the values you mark as trusted indeed are safe - because they were
+ * received from your server, sanitized by your library, etc. You can organize your codebase to
+ * help with this - perhaps allowing only the files in a specific directory to do this.
+ * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then
+ * becomes a more manageable task.
+ *
+ * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
+ * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
+ * build the trusted versions of your values.
+ *
+ * ## How does it work?
+ *
+ * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
+ * $sce.getTrusted(context, value)} rather than to the value directly. Think of this function as
+ * a way to enforce the required security context in your data sink. Directives use {@link
+ * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs
+ * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also,
+ * when binding without directives, AngularJS will understand the context of your bindings
+ * automatically.
+ *
+ * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
+ * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly
+ * simplified):
+ *
+ * ```
+ * var ngBindHtmlDirective = ['$sce', function($sce) {
+ * return function(scope, element, attr) {
+ * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
+ * element.html(value || '');
+ * });
+ * };
+ * }];
+ * ```
+ *
+ * ## Impact on loading templates
+ *
+ * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
+ * `templateUrl`'s specified by {@link guide/directive directives}.
+ *
+ * By default, Angular only loads templates from the same domain and protocol as the application
+ * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl
+ * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or
+ * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
+ * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
+ *
+ * *Please note*:
+ * The browser's
+ * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
+ * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
+ * policy apply in addition to this and may further restrict whether the template is successfully
+ * loaded. This means that without the right CORS policy, loading templates from a different domain
+ * won't work on all browsers. Also, loading templates from `file://` URL does not work on some
+ * browsers.
+ *
+ * ## This feels like too much overhead
+ *
+ * It's important to remember that SCE only applies to interpolation expressions.
+ *
+ * If your expressions are constant literals, they're automatically trusted and you don't need to
+ * call `$sce.trustAs` on them (e.g.
+ * `
`) just works. The `$sceDelegate` will
+ * also use the `$sanitize` service if it is available when binding untrusted values to
+ * `$sce.HTML` context. AngularJS provides an implementation in `angular-sanitize.js`, and if you
+ * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in
+ * your application.
+ *
+ * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
+ * templates in `ng-include` from your application's domain without having to even know about SCE.
+ * It blocks loading templates from other domains or loading templates over http from an https
+ * served document. You can change these by setting your own custom {@link
+ * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
+ * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
+ *
+ * This significantly reduces the overhead. It is far easier to pay the small overhead and have an
+ * application that's secure and can be audited to verify that with much more ease than bolting
+ * security onto an application later.
+ *
+ *
+ *
+ *
+ *
+ *
User comments
+ * By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when
+ * $sanitize is available. If $sanitize isn't available, this results in an error instead of an
+ * exploit.
+ *
+ *
+ * {{userComment.name}} :
+ *
+ *
+ *
+ *
+ *
+ *
+ * angular.module('mySceApp', ['ngSanitize'])
+ * .controller('AppController', ['$http', '$templateCache', '$sce',
+ * function AppController($http, $templateCache, $sce) {
+ * var self = this;
+ * $http.get('test_data.json', {cache: $templateCache}).then(function(response) {
+ * self.userComments = response.data;
+ * });
+ * self.explicitlyTrustedHtml = $sce.trustAsHtml(
+ * 'Hover over this text. ');
+ * }]);
+ *
+ *
+ *
+ * [
+ * { "name": "Alice",
+ * "htmlComment":
+ * "Is anyone reading this? "
+ * },
+ * { "name": "Bob",
+ * "htmlComment": "Yes! Am I the only other one?"
+ * }
+ * ]
+ *
+ *
+ *
+ * describe('SCE doc demo', function() {
+ * it('should sanitize untrusted values', function() {
+ * expect(element.all(by.css('.htmlComment')).first().getAttribute('innerHTML'))
+ * .toBe('Is anyone reading this? ');
+ * });
+ *
+ * it('should NOT sanitize explicitly trusted values', function() {
+ * expect(element(by.id('explicitlyTrustedHtml')).getAttribute('innerHTML')).toBe(
+ * 'Hover over this text. ');
+ * });
+ * });
+ *
+ *
+ *
+ *
+ *
+ * ## Can I disable SCE completely?
+ *
+ * Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits
+ * for little coding overhead. It will be much harder to take an SCE disabled application and
+ * either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE
+ * for cases where you have a lot of existing code that was written before SCE was introduced and
+ * you're migrating them a module at a time. Also do note that this is an app-wide setting, so if
+ * you are writing a library, you will cause security bugs applications using it.
+ *
+ * That said, here's how you can completely disable SCE:
+ *
+ * ```
+ * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
+ * // Completely disable SCE. For demonstration purposes only!
+ * // Do not use in new projects or libraries.
+ * $sceProvider.enabled(false);
+ * });
+ * ```

- * @ngdoc filter
- * @name filter
- * @kind function
- *
- * @description
- * Selects a subset of items from `array` and returns it as a new array.
- *
- * @param {Array} array The source array.
- *
- * **Note**: If the array contains objects that reference themselves, filtering is not possible.
- *
- * @param {string|Object|function()} expression The predicate to be used for selecting items from
- * `array`.
- *
- * Can be one of:
- *
- * - `string`: The string is used for matching against the contents of the `array`. All strings or
- * objects with string properties in `array` that match this string will be returned. This also
- * applies to nested object properties.
- * The predicate can be negated by prefixing the string with `!`.
- *
- * - `Object`: A pattern object can be used to filter specific properties on objects contained
- * by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
- * which have property `name` containing "M" and property `phone` containing "1". A special
- * property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match
- * against any property of the object or its nested object properties. That's equivalent to the
- * simple substring match with a `string` as described above. The special property name can be
- * overwritten, using the `anyPropertyKey` parameter.
- * The predicate can be negated by prefixing the string with `!`.
- * For example `{name: "!M"}` predicate will return an array of items which have property `name`
- * not containing "M".
- *
- * Note that a named property will match properties on the same level only, while the special
- * `$` property will match properties on the same level or deeper. E.g. an array item like
- * `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
- * **will** be matched by `{$: 'John'}`.
- *
- * - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
- * The function is called for each element of the array, with the element, its index, and
- * the entire array itself as arguments.
- *
- * The final result is an array of those elements that the predicate returned true for.
- *
- * @param {function(actual, expected)|true|false} [comparator] Comparator which is used in
- * determining if values retrieved using `expression` (when it is not a function) should be
- * considered a match based on the the expected value (from the filter expression) and actual
- * value (from the object in the array).
- *
- * Can be one of:
- *
- * - `function(actual, expected)`:
- * The function will be given the object value and the predicate value to compare and
- * should return true if both values should be considered equal.
- *
- * - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
- * This is essentially strict comparison of expected and actual.
- *
- * - `false`: A short hand for a function which will look for a substring match in a case
- * insensitive way. Primitive values are converted to strings. Objects are not compared against
- * primitives, unless they have a custom `toString` method (e.g. `Date` objects).
- *
- *
- * Defaults to `false`.
- *
- * @param {string} [anyPropertyKey] The special property name that matches against any property.
- * By default `$`.
- *
- * @example
-
-
-
-
- Search:
-
- Name Phone
- {{friend.name}}
- {{friend.phone}}
-
-
- Any: Name only Phone only Equality
- Name Phone
- {{friendObj.name}}
- {{friendObj.phone}}

+ /* Design notes on the default implementation for SCE.
+ *
+ * The API contract for the SCE delegate
+ * -------------------------------------
+ * The SCE delegate object must provide the following 3 methods:
+ *
+ * - trustAs(contextEnum, value)
+ * This method is used to tell the SCE service that the provided value is OK to use in the
+ * contexts specified by contextEnum. It must return an object that will be accepted by
+ * getTrusted() for a compatible contextEnum and return this value.
+ *
+ * - valueOf(value)
+ * For values that were not produced by trustAs(), return them as is. For values that were
+ * produced by trustAs(), return the corresponding input value to trustAs. Basically, if
+ * trustAs is wrapping the given values into some type, this operation unwraps it when given
+ * such a value.
+ *
+ * - getTrusted(contextEnum, value)
+ * This function should return the a value that is safe to use in the context specified by
+ * contextEnum or throw and exception otherwise.
+ *
+ * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
+ * opaque or wrapped in some holder object. That happens to be an implementation detail. For
+ * instance, an implementation could maintain a registry of all trusted objects by context. In
+ * such a case, trustAs() would return the same object that was passed in. getTrusted() would
+ * return the same object passed in if it was found in the registry under a compatible context or
+ * throw an exception otherwise. An implementation might only wrap values some of the time based
+ * on some criteria. getTrusted() might return a value and not throw an exception for special
+ * constants or objects even if not wrapped. All such implementations fulfill this contract.
+ *
+ *
+ * A note on the inheritance model for SCE contexts
+ * ------------------------------------------------
+ * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This
+ * is purely an implementation details.
+ *
+ * The contract is simply this:
+ *
+ * getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
+ * will also succeed.
+ *
+ * Inheritance happens to capture this in a natural way. In some future, we may not use
+ * inheritance anymore. That is OK because no code outside of sce.js and sceSpecs.js would need to
+ * be aware of this detail.

+ *
+ * Implementation Notes for non-IE browsers
+ * ----------------------------------------
+ * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
+ * results both in the normalizing and parsing of the URL. Normalizing means that a relative
+ * URL will be resolved into an absolute URL in the context of the application document.
+ * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
+ * properties are all populated to reflect the normalized URL. This approach has wide
+ * compatibility - Safari 1+, Mozilla 1+ etc. See
+ * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
+ *
+ * Implementation Notes for IE
+ * ---------------------------
+ * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
+ * browsers. However, the parsed components will not be set if the URL assigned did not specify
+ * them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We
+ * work around that by performing the parsing in a 2nd step by taking a previously normalized
+ * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the
+ * properties such as protocol, hostname, port, etc.
+ *

- * @description
- * Formats `date` to a string based on the requested `format`.
- *
- * `format` string can be composed of the following elements:
- *
- * * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
- * * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
- * * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
- * * `'MMMM'`: Month in year (January-December)
- * * `'MMM'`: Month in year (Jan-Dec)
- * * `'MM'`: Month in year, padded (01-12)
- * * `'M'`: Month in year (1-12)
- * * `'LLLL'`: Stand-alone month in year (January-December)
- * * `'dd'`: Day in month, padded (01-31)
- * * `'d'`: Day in month (1-31)
- * * `'EEEE'`: Day in Week,(Sunday-Saturday)
- * * `'EEE'`: Day in Week, (Sun-Sat)
- * * `'HH'`: Hour in day, padded (00-23)
- * * `'H'`: Hour in day (0-23)
- * * `'hh'`: Hour in AM/PM, padded (01-12)
- * * `'h'`: Hour in AM/PM, (1-12)
- * * `'mm'`: Minute in hour, padded (00-59)
- * * `'m'`: Minute in hour (0-59)
- * * `'ss'`: Second in minute, padded (00-59)
- * * `'s'`: Second in minute (0-59)
- * * `'sss'`: Millisecond in second, padded (000-999)
- * * `'a'`: AM/PM marker
- * * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
- * * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year
- * * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year
- * * `'G'`, `'GG'`, `'GGG'`: The abbreviated form of the era string (e.g. 'AD')
- * * `'GGGG'`: The long form of the era string (e.g. 'Anno Domini')
- *
- * `format` string can also be one of the following predefined
- * {@link guide/i18n localizable formats}:
- *
- * * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
- * (e.g. Sep 3, 2010 12:05:08 PM)
- * * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 PM)
- * * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US locale
- * (e.g. Friday, September 3, 2010)
- * * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010)
- * * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010)
- * * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
- * * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM)
- * * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM)
- *
- * `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
- * `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
- * (e.g. `"h 'o''clock'"`).
- *
- * Any other characters in the `format` string will be output as-is.
- *
- * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
- * number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
- * shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
- * specified in the string input, the time is considered to be in the local timezone.
- * @param {string=} format Formatting rules (see Description). If not specified,
- * `mediumDate` is used.
- * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
- * continental US time zone abbreviations, but for general use, use a time zone offset, for
- * example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
- * If not specified, the timezone of the browser will be used.
- * @returns {string} Formatted string or the input if input is not recognized as date/millis.
- *

+ * @ngdoc filter
+ * @name filter
+ * @kind function
+ *
+ * @description
+ * Selects a subset of items from `array` and returns it as a new array.
+ *
+ * @param {Array} array The source array.
+ *
+ * **Note**: If the array contains objects that reference themselves, filtering is not possible.
+ *
+ * @param {string|Object|function()} expression The predicate to be used for selecting items from
+ * `array`.
+ *
+ * Can be one of:
+ *
+ * - `string`: The string is used for matching against the contents of the `array`. All strings or
+ * objects with string properties in `array` that match this string will be returned. This also
+ * applies to nested object properties.
+ * The predicate can be negated by prefixing the string with `!`.
+ *
+ * - `Object`: A pattern object can be used to filter specific properties on objects contained
+ * by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
+ * which have property `name` containing "M" and property `phone` containing "1". A special
+ * property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match
+ * against any property of the object or its nested object properties. That's equivalent to the
+ * simple substring match with a `string` as described above. The special property name can be
+ * overwritten, using the `anyPropertyKey` parameter.
+ * The predicate can be negated by prefixing the string with `!`.
+ * For example `{name: "!M"}` predicate will return an array of items which have property `name`
+ * not containing "M".
+ *
+ * Note that a named property will match properties on the same level only, while the special
+ * `$` property will match properties on the same level or deeper. E.g. an array item like
+ * `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
+ * **will** be matched by `{$: 'John'}`.
+ *
+ * - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
+ * The function is called for each element of the array, with the element, its index, and
+ * the entire array itself as arguments.
+ *
+ * The final result is an array of those elements that the predicate returned true for.
+ *
+ * @param {function(actual, expected)|true|false} [comparator] Comparator which is used in
+ * determining if values retrieved using `expression` (when it is not a function) should be
+ * considered a match based on the the expected value (from the filter expression) and actual
+ * value (from the object in the array).
+ *
+ * Can be one of:
+ *
+ * - `function(actual, expected)`:
+ * The function will be given the object value and the predicate value to compare and
+ * should return true if both values should be considered equal.
+ *
+ * - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
+ * This is essentially strict comparison of expected and actual.
+ *
+ * - `false`: A short hand for a function which will look for a substring match in a case
+ * insensitive way. Primitive values are converted to strings. Objects are not compared against
+ * primitives, unless they have a custom `toString` method (e.g. `Date` objects).
+ *
+ *
+ * Defaults to `false`.
+ *
+ * @param {string} [anyPropertyKey] The special property name that matches against any property.
+ * By default `$`.
+ *
+ * @example
+
+
+
+
+ Search:
+
+ Name Phone
+ {{friend.name}}

-/**
- * @ngdoc filter
- * @name orderBy
- * @kind function
- *
- * @description
- * Returns an array containing the items from the specified `collection`, ordered by a `comparator`
- * function based on the values computed using the `expression` predicate.
- *
- * For example, `[{id: 'foo'}, {id: 'bar'}] | orderBy:'id'` would result in
- * `[{id: 'bar'}, {id: 'foo'}]`.
- *
- * The `collection` can be an Array or array-like object (e.g. NodeList, jQuery object, TypedArray,
- * String, etc).
- *
- * The `expression` can be a single predicate, or a list of predicates each serving as a tie-breaker
- * for the preceding one. The `expression` is evaluated against each item and the output is used
- * for comparing with other items.
- *
- * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in
- * ascending order.
- *
- * The comparison is done using the `comparator` function. If none is specified, a default, built-in
- * comparator is used (see below for details - in a nutshell, it compares numbers numerically and
- * strings alphabetically).
- *
- * ### Under the hood
- *
- * Ordering the specified `collection` happens in two phases:
- *
- * 1. All items are passed through the predicate (or predicates), and the returned values are saved
- * along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed
- * through a predicate that extracts the value of the `label` property, would be transformed to:
- * ```
- * {
- * value: 'foo',
- * type: 'string',
- * index: ...
- * }
- * ```
- * 2. The comparator function is used to sort the items, based on the derived values, types and
- * indices.
- *
- * If you use a custom comparator, it will be called with pairs of objects of the form
- * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal
- * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the
- * second, or `1` otherwise.
- *
- * In order to ensure that the sorting will be deterministic across platforms, if none of the
- * specified predicates can distinguish between two items, `orderBy` will automatically introduce a
- * dummy predicate that returns the item's index as `value`.
- * (If you are using a custom comparator, make sure it can handle this predicate as well.)
- *
- * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted
- * value for an item, `orderBy` will try to convert that object to a primitive value, before passing
- * it to the comparator. The following rules govern the conversion:
- *
- * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be
- * used instead.)=} expression - A predicate (or list of
- * predicates) to be used by the comparator to determine the order of elements.
- *
- * Can be one of:
- *
- * - `Function`: A getter function. This function will be called with each item as argument and
- * the return value will be used for sorting.
- * - `string`: An Angular expression. This expression will be evaluated against each item and the
- * result will be used for sorting. For example, use `'label'` to sort by a property called
- * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
- * property.

+ * Formats `date` to a string based on the requested `format`.
+ *
+ * `format` string can be composed of the following elements:
+ *
+ * * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
+ * * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
+ * * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
+ * * `'MMMM'`: Month in year (January-December)
+ * * `'MMM'`: Month in year (Jan-Dec)
+ * * `'MM'`: Month in year, padded (01-12)
+ * * `'M'`: Month in year (1-12)
+ * * `'LLLL'`: Stand-alone month in year (January-December)
+ * * `'dd'`: Day in month, padded (01-31)
+ * * `'d'`: Day in month (1-31)
+ * * `'EEEE'`: Day in Week,(Sunday-Saturday)
+ * * `'EEE'`: Day in Week, (Sun-Sat)
+ * * `'HH'`: Hour in day, padded (00-23)
+ * * `'H'`: Hour in day (0-23)
+ * * `'hh'`: Hour in AM/PM, padded (01-12)
+ * * `'h'`: Hour in AM/PM, (1-12)
+ * * `'mm'`: Minute in hour, padded (00-59)
+ * * `'m'`: Minute in hour (0-59)
+ * * `'ss'`: Second in minute, padded (00-59)
+ * * `'s'`: Second in minute (0-59)
+ * * `'sss'`: Millisecond in second, padded (000-999)
+ * * `'a'`: AM/PM marker
+ * * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
+ * * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year
+ * * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year
+ * * `'G'`, `'GG'`, `'GGG'`: The abbreviated form of the era string (e.g. 'AD')
+ * * `'GGGG'`: The long form of the era string (e.g. 'Anno Domini')
+ *
+ * `format` string can also be one of the following predefined
+ * {@link guide/i18n localizable formats}:
+ *
+ * * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
+ * (e.g. Sep 3, 2010 12:05:08 PM)
+ * * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 PM)
+ * * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US locale
+ * (e.g. Friday, September 3, 2010)
+ * * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010)
+ * * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010)
+ * * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)

+ *
+ * `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
+ * `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
+ * (e.g. `"h 'o''clock'"`).
+ *
+ * Any other characters in the `format` string will be output as-is.
+ *
+ * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
+ * number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
+ * shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
+ * specified in the string input, the time is considered to be in the local timezone.
+ * @param {string=} format Formatting rules (see Description). If not specified,
+ * `mediumDate` is used.
+ * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
+ * continental US time zone abbreviations, but for general use, use a time zone offset, for

+ *
+ * For example, `[{id: 'foo'}, {id: 'bar'}] | orderBy:'id'` would result in
+ * `[{id: 'bar'}, {id: 'foo'}]`.
+ *
+ * The `collection` can be an Array or array-like object (e.g. NodeList, jQuery object, TypedArray,
+ * String, etc).
+ *
+ * The `expression` can be a single predicate, or a list of predicates each serving as a tie-breaker
+ * for the preceding one. The `expression` is evaluated against each item and the output is used
+ * for comparing with other items.
+ *
+ * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in
+ * ascending order.
+ *
+ * The comparison is done using the `comparator` function. If none is specified, a default, built-in
+ * comparator is used (see below for details - in a nutshell, it compares numbers numerically and
+ * strings alphabetically).
+ *
+ * ### Under the hood
+ *
+ * Ordering the specified `collection` happens in two phases:
+ *
+ * 1. All items are passed through the predicate (or predicates), and the returned values are saved
+ * along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed
+ * through a predicate that extracts the value of the `label` property, would be transformed to:
+ * ```
+ * {
+ * value: 'foo',
+ * type: 'string',
+ * index: ...
+ * }
+ * ```
+ * 2. The comparator function is used to sort the items, based on the derived values, types and
+ * indices.
+ *
+ * If you use a custom comparator, it will be called with pairs of objects of the form
+ * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal
+ * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the
+ * second, or `1` otherwise.
+ *
+ * In order to ensure that the sorting will be deterministic across platforms, if none of the
+ * specified predicates can distinguish between two items, `orderBy` will automatically introduce a
+ * dummy predicate that returns the item's index as `value`.
+ * (If you are using a custom comparator, make sure it can handle this predicate as well.)
+ *
+ * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted
+ * value for an item, `orderBy` will try to convert that object to a primitive value, before passing
+ * it to the comparator. The following rules govern the conversion:
+ *
+ * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be
+ * used instead.)=} expression - A predicate (or list of
+ * predicates) to be used by the comparator to determine the order of elements.
+ *
+ * Can be one of:
+ *
+ * - `Function`: A getter function. This function will be called with each item as argument and
+ * the return value will be used for sorting.
+ * - `string`: An Angular expression. This expression will be evaluated against each item and the
+ * result will be used for sorting. For example, use `'label'` to sort by a property called
+ * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
+ * property.

-/**
- * @ngdoc directive
- * @name ngList
- *
- * @description
- * Text input that converts between a delimited string and an array of strings. The default
- * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
- * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
- *
- * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
- * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
- * list item is respected. This implies that the user of the directive is responsible for
- * dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
- * tab or newline character.
- * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
- * when joining the list items back together) and whitespace around each list item is stripped
- * before it is added to the model.
- *
- * ### Example with Validation
- *
- *
- *
- * angular.module('listExample', [])
- * .controller('ExampleController', ['$scope', function($scope) {
- * $scope.names = ['morpheus', 'neo', 'trinity'];
- * }]);
- *
- *
- *
- *
- *
- * var listInput = element(by.model('names'));
- * var names = element(by.exactBinding('names'));
- * var valid = element(by.binding('myForm.namesInput.$valid'));
- * var error = element(by.css('span.error'));
- *
- * it('should initialize to model', function() {
- * expect(names.getText()).toContain('["morpheus","neo","trinity"]');
- * expect(valid.getText()).toContain('true');
- * expect(error.getCssValue('display')).toBe('none');
- * });
- *
- * it('should be invalid if empty', function() {
- * listInput.clear();
- * listInput.sendKeys('');
- *
- * expect(names.getText()).toContain('');
- * expect(valid.getText()).toContain('false');
- * expect(error.getCssValue('display')).not.toBe('none');
- * });
- *
- *
- *
- * ### Example - splitting on newline
- *
- *
- *
- * {{ list | json }}
- *
- *
- * it("should split the text by newlines", function() {
- * var listInput = element(by.model('list'));
- * var output = element(by.binding('list | json'));
- * listInput.sendKeys('abc\ndef\nghi');
- * expect(output.getText()).toContain('[\n "abc",\n "def",\n "ghi"\n]');

+ * String. See {@link ngModel.NgModelController#$setViewValue} for information about when the $viewValue
+ * is set.
+ *
+ * @property {*} $modelValue The value in the model that the control is bound to.
+ *
+ * @property {Array.} $parsers Array of functions to execute, as a pipeline, whenever
+ * the control updates the ngModelController with a new {@link ngModel.NgModelController#$viewValue
+ `$viewValue`} from the DOM, usually via user input.
+ See {@link ngModel.NgModelController#$setViewValue `$setViewValue()`} for a detailed lifecycle explanation.
+ Note that the `$parsers` are not called when the bound ngModel expression changes programmatically.
+
+ The functions are called in array order, each passing
+ its return value through to the next. The last return value is forwarded to the
+ {@link ngModel.NgModelController#$validators `$validators`} collection.
+
+ Parsers are used to sanitize / convert the {@link ngModel.NgModelController#$viewValue
+ `$viewValue`}.
+
+ Returning `undefined` from a parser means a parse error occurred. In that case,
+ no {@link ngModel.NgModelController#$validators `$validators`} will run and the `ngModel`
+ will be set to `undefined` unless {@link ngModelOptions `ngModelOptions.allowInvalid`}
+ is set to `true`. The parse error is stored in `ngModel.$error.parse`.
+
+ This simple example shows a parser that would convert text input value to lowercase:
+ * ```js
+ * function parse(value) {
+ * if (value) {
+ * return value.toLowerCase();
+ * }
+ * }
+ * ngModelController.$parsers.push(parse);
+ * ```
+
+ *
+ * @property {Array.} $formatters Array of functions to execute, as a pipeline, whenever
+ the bound ngModel expression changes programmatically. The `$formatters` are not called when the
+ value of the control is changed by user interaction.
+
+ Formatters are used to format / convert the {@link ngModel.NgModelController#$modelValue
+ `$modelValue`} for display in the control.
+
+ The functions are called in reverse array order, each passing the value through to the
+ next. The last return value is used as the actual DOM value.
+
+ This simple example shows a formatter that would convert the model value to uppercase:
+
+ * ```js
+ * function format(value) {
+ * if (value) {
+ * return value.toUpperCase();
+ * }
+ * }
+ * ngModel.$formatters.push(format);
+ * ```
+ *
+ * @property {Object.} $validators A collection of validators that are applied
+ * whenever the model value changes. The key value within the object refers to the name of the
+ * validator while the function refers to the validation operation. The validation operation is
+ * provided with the model value as an argument and must return a true or false value depending
+ * on the response of that validation.
+ *
+ * ```js
+ * ngModel.$validators.validCharacters = function(modelValue, viewValue) {
+ * var value = modelValue || viewValue;
+ * return /[0-9]+/.test(value) &&
+ * /[a-z]+/.test(value) &&
+ * /[A-Z]+/.test(value) &&
+ * /\W+/.test(value);
+ * };
+ * ```
+ *
+ * @property {Object.} $asyncValidators A collection of validations that are expected to
+ * perform an asynchronous validation (e.g. a HTTP request). The validation function that is provided
+ * is expected to return a promise when it is run during the model validation process. Once the promise
+ * is delivered then the validation status will be set to true when fulfilled and false when rejected.
+ * When the asynchronous validators are triggered, each of the validators will run in parallel and the model
+ * value will only be updated once all validators have been fulfilled. As long as an asynchronous validator
+ * is unfulfilled, its key will be added to the controllers `$pending` property. Also, all asynchronous validators
+ * will only run once all synchronous validators have passed.
+ *
+ * Please note that if $http is used then it is important that the server returns a success HTTP response code
+ * in order to fulfill the validation and a status level of `4xx` in order to reject the validation.
+ *
+ * ```js
+ * ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
+ * var value = modelValue || viewValue;
+ *
+ * // Lookup user by username
+ * return $http.get('/api/users/' + value).
+ * then(function resolved() {
+ * //username exists, this means validation fails
+ * return $q.reject('exists');
+ * }, function rejected() {
+ * //username does not exist, therefore this validation passes
+ * return true;
+ * });
+ * };
+ * ```
+ *
+ * @property {Array.} $viewChangeListeners Array of functions to execute whenever the
+ * view value has changed. It is called with no arguments, and its return value is ignored.
+ * This can be used in place of additional $watches against the model value.
+ *
+ * @property {Object} $error An object hash with all failing validator ids as keys.
+ * @property {Object} $pending An object hash with all pending validator ids as keys.
+ *
+ * @property {boolean} $untouched True if control has not lost focus yet.
+ * @property {boolean} $touched True if control has lost focus.
+ * @property {boolean} $pristine True if user has not interacted with the control yet.
+ * @property {boolean} $dirty True if user has already interacted with the control.
+ * @property {boolean} $valid True if there is no error.
+ * @property {boolean} $invalid True if at least one error on the control.
+ * @property {string} $name The name attribute of the control.

+ *
+ * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
+ * The controller contains services for data-binding, validation, CSS updates, and value formatting
+ * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
+ * listening to DOM events.
+ * Such DOM related logic should be provided by other directives which make use of
+ * `NgModelController` for data-binding to control elements.
+ * Angular provides this DOM logic for most {@link input `input`} elements.
+ * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
+ * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
+ *
+ * @example
+ * ### Custom Control Example
+ * This example shows how to use `NgModelController` with a custom control to achieve
+ * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
+ * collaborate together to achieve the desired result.
+ *
+ * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
+ * contents be edited in place by the user.
+ *
+ * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
+ * module to automatically remove "bad" content like inline event listener (e.g. ``).
+ * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
+ * that content using the `$sce` service.
+ *
+ *

+ *
+ * @description
+ * Update the view value.
+ *
+ * This method should be called when a control wants to change the view value; typically,
+ * this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
+ * directive calls it when the value of the input changes and {@link ng.directive:select select}
+ * calls it when an option is selected.
+ *
+ * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
+ * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
+ * value is sent directly for processing through the `$parsers` pipeline. After this, the `$validators` and
+ * `$asyncValidators` are called and the value is applied to `$modelValue`.
+ * Finally, the value is set to the **expression** specified in the `ng-model` attribute and
+ * all the registered change listeners, in the `$viewChangeListeners` list are called.
+ *
+ * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
+ * and the `default` trigger is not listed, all those actions will remain pending until one of the
+ * `updateOn` events is triggered on the DOM element.
+ * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
+ * directive is used with a custom debounce for this particular event.
+ * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
+ * is specified, once the timer runs out.
+ *
+ * When used with standard inputs, the view value will always be a string (which is in some cases
+ * parsed into another type, such as a `Date` object for `input[date]`.)
+ * However, custom controls might also pass objects to this method. In this case, we should make
+ * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
+ * perform a deep watch of objects, it only looks for a change of identity. If you only change
+ * the property of the object then ngModel will not realize that the object has changed and
+ * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
+ * not change properties of the copy once it has been passed to `$setViewValue`.
+ * Otherwise you may cause the model value on the scope to change incorrectly.
+ *
+ *
+ * In any case, the value passed to the method should always reflect the current value
+ * of the control. For example, if you are calling `$setViewValue` for an input element,
+ * you should pass the input DOM value. Otherwise, the control and the scope model become
+ * out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
+ * the control's DOM value in any way. If we want to change the control's DOM value
+ * programmatically, we should update the `ngModel` scope expression. Its new value will be
+ * picked up by the model controller, which will run it through the `$formatters`, `$render` it
+ * to update the DOM, and finally call `$validate` on it.

- * @property {*} $viewValue The actual value from the control's view. For `input` elements, this is a

- * is set.
- *
- * @property {*} $modelValue The value in the model that the control is bound to.
- *
- * @property {Array.} $parsers Array of functions to execute, as a pipeline, whenever

- `$viewValue`} from the DOM, usually via user input.
- See {@link ngModel.NgModelController#$setViewValue `$setViewValue()`} for a detailed lifecycle explanation.
- Note that the `$parsers` are not called when the bound ngModel expression changes programmatically.
-
- The functions are called in array order, each passing
- its return value through to the next. The last return value is forwarded to the
- {@link ngModel.NgModelController#$validators `$validators`} collection.
-
- Parsers are used to sanitize / convert the {@link ngModel.NgModelController#$viewValue
- `$viewValue`}.
-
- Returning `undefined` from a parser means a parse error occurred. In that case,
- no {@link ngModel.NgModelController#$validators `$validators`} will run and the `ngModel`
- will be set to `undefined` unless {@link ngModelOptions `ngModelOptions.allowInvalid`}
- is set to `true`. The parse error is stored in `ngModel.$error.parse`.
-
- This simple example shows a parser that would convert text input value to lowercase:

- * @property {Array.} $formatters Array of functions to execute, as a pipeline, whenever
- the bound ngModel expression changes programmatically. The `$formatters` are not called when the
- value of the control is changed by user interaction.
-
- Formatters are used to format / convert the {@link ngModel.NgModelController#$modelValue
- `$modelValue`} for display in the control.
-
- The functions are called in reverse array order, each passing the value through to the
- next. The last return value is used as the actual DOM value.
-
- This simple example shows a formatter that would convert the model value to uppercase:
-
- * ```js
- * function format(value) {
- * if (value) {
- * return value.toUpperCase();
- * }
- * }
- * ngModel.$formatters.push(format);
- * ```
- *
- * @property {Object.} $validators A collection of validators that are applied
- * whenever the model value changes. The key value within the object refers to the name of the
- * validator while the function refers to the validation operation. The validation operation is
- * provided with the model value as an argument and must return a true or false value depending
- * on the response of that validation.
- *
- * ```js
- * ngModel.$validators.validCharacters = function(modelValue, viewValue) {
- * var value = modelValue || viewValue;
- * return /[0-9]+/.test(value) &&
- * /[a-z]+/.test(value) &&
- * /[A-Z]+/.test(value) &&
- * /\W+/.test(value);
- * };
- * ```
- *
- * @property {Object.} $asyncValidators A collection of validations that are expected to
- * perform an asynchronous validation (e.g. a HTTP request). The validation function that is provided
- * is expected to return a promise when it is run during the model validation process. Once the promise
- * is delivered then the validation status will be set to true when fulfilled and false when rejected.
- * When the asynchronous validators are triggered, each of the validators will run in parallel and the model
- * value will only be updated once all validators have been fulfilled. As long as an asynchronous validator
- * is unfulfilled, its key will be added to the controllers `$pending` property. Also, all asynchronous validators
- * will only run once all synchronous validators have passed.
- *
- * Please note that if $http is used then it is important that the server returns a success HTTP response code
- * in order to fulfill the validation and a status level of `4xx` in order to reject the validation.
- *
- * ```js
- * ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
- * var value = modelValue || viewValue;
- *
- * // Lookup user by username
- * return $http.get('/api/users/' + value).
- * then(function resolved() {
- * //username exists, this means validation fails
- * return $q.reject('exists');
- * }, function rejected() {
- * //username does not exist, therefore this validation passes
- * return true;
- * });
- * };
- * ```
- *
- * @property {Array.} $viewChangeListeners Array of functions to execute whenever the
- * view value has changed. It is called with no arguments, and its return value is ignored.
- * This can be used in place of additional $watches against the model value.
- *
- * @property {Object} $error An object hash with all failing validator ids as keys.
- * @property {Object} $pending An object hash with all pending validator ids as keys.
- *
- * @property {boolean} $untouched True if control has not lost focus yet.
- * @property {boolean} $touched True if control has lost focus.
- * @property {boolean} $pristine True if user has not interacted with the control yet.
- * @property {boolean} $dirty True if user has already interacted with the control.
- * @property {boolean} $valid True if there is no error.
- * @property {boolean} $invalid True if at least one error on the control.
- * @property {string} $name The name attribute of the control.

- *
- * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
- * The controller contains services for data-binding, validation, CSS updates, and value formatting
- * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
- * listening to DOM events.
- * Such DOM related logic should be provided by other directives which make use of
- * `NgModelController` for data-binding to control elements.
- * Angular provides this DOM logic for most {@link input `input`} elements.
- * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
- * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
- *
- * @example
- * ### Custom Control Example
- * This example shows how to use `NgModelController` with a custom control to achieve
- * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
- * collaborate together to achieve the desired result.
- *
- * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
- * contents be edited in place by the user.
- *
- * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
- * module to automatically remove "bad" content like inline event listener (e.g. ``).
- * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
- * that content using the `$sce` service.
- *

*
- * Since `ng-model` does not do a deep watch, `$render()` is only invoked if the values of

+ * # CSS classes
+ * The following CSS classes are added and removed on the associated input/select/textarea element
+ * depending on the validity of the model.
*
- * If you have an input that uses `ng-model-options` to set up debounced updates or updates that
- * depend on special events such as `blur`, there can be a period when the `$viewValue` is out of
- * sync with the ngModel's `$modelValue`.
+ * - `ng-valid`: the model is valid
+ * - `ng-invalid`: the model is invalid
+ * - `ng-valid-[key]`: for each valid key added by `$setValidity`
+ * - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
+ * - `ng-pristine`: the control hasn't been interacted with yet
+ * - `ng-dirty`: the control has been interacted with
+ * - `ng-touched`: the control has been blurred
+ * - `ng-untouched`: the control hasn't been blurred
+ * - `ng-pending`: any `$asyncValidators` are unfulfilled
+ * - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
+ * by the {@link ngModel.NgModelController#$isEmpty} method
+ * - `ng-not-empty`: the view contains a non-empty value
*
- * In this case, you can use `$rollbackViewValue()` to manually cancel the debounced / future update
- * and reset the input to the last committed view value.
+ * Keep in mind that ngAnimate can detect each of these classes when added and removed.
*
- * It is also possible that you run into difficulties if you try to update the ngModel's `$modelValue`
- * programmatically before these debounced/future events have resolved/occurred, because Angular's
- * dirty checking mechanism is not able to tell whether the model has actually changed or not.
+ * ## Animation Hooks
*
- * The `$rollbackViewValue()` method should be called before programmatically changing the model of an
- * input which may have such events pending. This is important in order to make sure that the
- * input field will be updated with the new model value and any pending operations are cancelled.
+ * Animations within models are triggered when any of the associated CSS classes are added and removed
+ * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
+ * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
+ * The animations that are triggered within ngModel are similar to how they work in ngClass and
+ * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
*
- *
- *
- * angular.module('cancel-update-example', [])
+ * The following example shows a simple way to utilize CSS transitions to style an input element
+ * that has been rendered as invalid after it has been validated:
*
- * .controller('CancelUpdateController', ['$scope', function($scope) {
- * $scope.model = {value1: '', value2: ''};
+ *
+ * //be sure to include ngAnimate as a module to hook into more
+ * //advanced animations
+ * .my-input {
+ * transition:0.5s linear all;
+ * background: white;
+ * }
+ * .my-input.ng-invalid {
+ * background: red;
+ * color:white;
+ * }
+ *
*
- * $scope.setEmpty = function(e, value, rollback) {
- * if (e.keyCode === 27) {
- * e.preventDefault();
- * if (rollback) {
- * $scope.myForm[value].$rollbackViewValue();
- * }
- * $scope.model[value] = '';
- * }
- * };
- * }]);
- *
- *
- *
- *
Both of these inputs are only updated if they are blurred. Hitting escape should
- * empty them. Follow these steps and observe the difference:
- *
- * Type something in the input. You will see that the model is not yet updated
- * Press the Escape key.
- *
- * In the first example, nothing happens, because the model is already '', and no
- * update is detected. If you blur the input, the model will be set to the current view.
- *
- * In the second example, the pending update is cancelled, and the input is set back
- * to the last committed view value (''). Blurring the input does nothing.
