Type Parameters:

M - the type of the metadata annotation

All Superinterfaces:

ReleasableReferenceManager

@Beta
public interface TypedReleasableReferenceManager<M extends Annotation>
extends ReleasableReferenceManager

A ReleasableReferenceManager for a scope that is annotated with an annotation that itself is annotated with CanReleaseReferences. That annotation is available as metadata() and may be useful at runtime to decide when to release references held by the scope.

For example:

    @CanReleaseReferences
   public  @interface SomeAnnotation {
     int value();
   }

    @Documented
    @Retention(RUNTIME)
    @SomeAnnotation(15)
    @Scope
   public  @interface MyScope {}

   // In a component that is (or has a subcomponent) annotated with  @MyScope:
    @Inject
   void manager(
        @ForReferenceReleasingScope(MyScope.class)
        TypedReferenceReleasingScope<SomeAnnotation> manager) {
     manager.metadata().value(); // returns 15
   }

This interface is implemented by Dagger.
