Annotation Type Sequence

@Documented
@Retention(value=RUNTIME)
@Target(value=METHOD)
public @interface Sequence

Identifies a Storable property capable of selecting its own value on insert, by a named sequence. Support for sequences is repository dependent, and if not supported, a PersistException is thrown when trying to insert. Explicitly specifying a value bypasses the sequence altogether.

Example:

 @PrimaryKey("userInfoID")
 public interface UserInfo extends Storable<UserInfo> {
     @Sequence("USER_ID_SEQ")
     long getUserInfoID();
     void setUserInfoID(long id);

     ...
 }
