core

extends ioc

1. @IocExt class decortator, use to define the class is Ioc extends module. it will auto run after registered to helper your to setup module.
2. add service resolve.
3. module inject.

Ioc

1. Register one class will auto register depdence class (must has a class decorator).

2. get Instance can auto create constructor param. (must has a class decorator or register in container).

decorators

1. @Abstract abstract class decorator.
2. @AutoRun class, method decorator, use to define the class auto run (via a method or not) after registered.
3. @AutoWried property or param decorator, use to auto wried type instance or value to the instance of one class with the decorator.
4. @Inject property or param decorator, use to auto wried type instance or value to the instance of one class with the decorator.
5. @Injectable class decortator, use to define the class. it can setting provider to some token, singleton or not.
6. @AutoWried method decorator.
7. @Param param decorator, use to auto wried type instance or value to the instance of one class with the decorator.
8. @Singleton class decortator, use to define the class is singleton.
9. @Providers Providers decorator, for class. use to add private ref service for the class.
10. @Refs Refs decorator, for class. use to define the class as a service for target.

AOP

It's a dynamic aop base on ioc.

define a Aspect class, must with decorator:

• @Aspect Aspect decorator, define for class. use to define class as aspect. it can setting provider to some token, singleton or not.

• @Before(matchstring|RegExp) method decorator, aop Before advice decorator.

• @After(matchstring|RegExp) method decorator, aop after advice decorator.

• @Around(matchstring|RegExp) method decorator, aop around advice decorator.

• @AfterThrowing(matchstring|RegExp) method decorator, aop AfterThrowing advice decorator.

• @AfterReturning(matchstring|RegExp) method decorator, aop AfterReturning advice decorator.

• @Pointcut(matchstring|RegExp) method decorator, aop Pointcut advice decorator.

boot

DI Module manager, application bootstrap. base on AOP.

• @DIModule DIModule decorator, use to define class as DI Module.
• @Bootstrap Bootstrap decorator, use to define class as bootstrp module.
• @Annotation Annotation decorator, use to define class build metadata config.
• @Message Message decorator, for class. use to define the class as message handle register in global message queue.

create Container

let container = new IocContainer();

Container is ioc root.

see @tsdi/ioc interface IIocContainer

see @tsdi/core interface IContainer

// 1. register a class
container.register(Person);

// 2. register a factory;
container.register(Person, (container)=> {
    ...
    return new Person(...);
});

// 3. register with keyword
container.register('keyword', Perosn);

// 4. register with alais
container.register(new Registration(Person, aliasname));

// register singleton
container.registerSingleton(Person)

// bind provider
container.bindProvider
// bind providers.
container.bindProviders

Injector is basic ioc injector.

see interface IInjector

// get the injector of Person class type injected.
let injector =  container.getInjector(Person);

// create new injector
let injector = container.createInjector();
// or create new injector via
let injector = container.getInstance(InjectorFactoryToken);

Invoke method

you can use yourself MethodAccessor by implement IMethodAccessor, register MethodAccessorToken with your MethodAccessor in container, see interface.

@Injectable
class Person {
    constructor() {

    }
    say() {
        return 'I love you.'
    }
}

@Injectable
class Child extends Person {
    constructor() {
        super();
    }
    say() {
        return 'Mama';
    }
}

class MethodTest {
    constructor() {

    }

    @AutoWried
    sayHello(person: Person) {
        return person.say();
    }
}

class MethodTest2 {
    constructor() {

    }

    @AutoWried()
    sayHello( @Inject(Child) person: Person) {
        return person.say();
    }
}

class MethodTest3 {
    constructor() {

    }

    @AutoWried
    sayHello( @Inject(Child) personA: Person, personB: Person) {
        return personA.say() + ', '  + personB.say();
    }
}

@Injectable
class Geet {
    constructor(private name: string){

    }

    print(hi?:string){
        return `${hi}, from ${this.name}`;
    }
}

container.register(Geet);

container.invoke(Geet, gt=> gt.print, ... //inject providers.)

let instance = container.resolve(Geet, )

container.invoke(instance, gt=> gt.print, ...//inject providers.);
container.invoke(instance, 'print', ...);

container.register(MethodTest);
container.invoke(MethodTest, 'sayHello');

container.register(MethodTest2);
container.invoke(MethodTest2, tg=> tg.sayHello);

container.register(MethodTest3);
container.invoke(MethodTest3, 'sayHello');
