Annotation Type InstanceDefault

@Target(value=TYPE)
@Retention(value=RUNTIME)
public @interface InstanceDefault

Used to link an instance implementation class to an injectable interface.

There can be one and only one @InstanceDefault PER scope class; A ThreadLocal variable is used to affect what types are injected;

Example:
static interface MyService{}

@SingletonDefault(implFor=MyService.class)

static class MyServiceImpl implements MyService{}

//returns a singleton instance of MyServiceImpl
MyService service = X_Inject.singleton(MyService.class);
