Annotations

The binding rules are defined through Java annotations. In this section there's a brief description of annotations defined in Kripton.

##Annotations for classes## You can decorate both class and field with generic and specific-format annotation. At class declaration's level it's possible to use the following annotation:

• @BindType: indicates class is binded. You have to use this annotation if you decorate same class with a specific-format binding annotation (i.e.: @BindTypeXml).
• @BindTypeXml: indicates a root XML element. It allow to define specific features valid only for xml format. If you define this annotation without @BindType, an exception will be throw.
• @BindTable (Android platform): allow to define database name binded to annotated Java class.

##Annotations for interfaces##

Kripton decorate interface to create SQLite database, DAO and its queries and SharedPreference.

• @BindDataSource (Android platform): defines a data source based on SQLite database.
• @BindDao (Android platform): defines a DAO to manage a specific database's table.
• @BindSharedPreferences (Android platform): allow to create a Shared Preference linked to annotated Java class.

##Annotations for fields## You can decorate only fields. No setter or getter annotation is defined. You can decorate field regardless its accessor. The annotations are:

• @Bind: states field is binded. This contains generic information about field persistance.
• @BindAdapter: allow to specify a custom type adapter for a specific field. For example, @BindAdapter can be used to persit a Date field as a long.
• @BindXml: contains informations about xml-persistence of field. It make possible to define how transform field in xml: tag, attribute or value of parent tag.
• @BindColumn: for a Java bean persisted on a SQLite database, this annotation allows to specify table column's features of a specific fields.

##Annotations for (interface) methods## There are some interface method's annotations:

• @SqlSelect: create a method to execute a SELECT SQL.
• @SqlInsert: create a method to execute a INSERT SQL.
• @SqlUpdate: create a method to execute a UPDATE SQL.
• @SqlDelete: create a method to execute a DELETE SQL.

##Annotations for (interface) method's parameters## There is only one annotations that you can use on method parameters:

• @SqlParam: allow to define SQL parameter name.
