Annotation Type Dependent

@Documented
 @Retention(value=RUNTIME)
 @Target(value={TYPE_USE,TYPE_PARAMETER})
public @interface Dependent

Refines the qualified type of the annotated field or variable based on the qualified type of the receiver. The annotation declares a relationship between multiple type qualifier hierarchies.

Example: Consider a field, lock, that is only initialized if the enclosing object (the receiver), is marked as ThreadSafe. Such a field can be declared as:

 private @Nullable @Dependent(result=NonNull.class, when=ThreadSafe.class)
   Lock lock;
