Annotation Interface Dependent

@Documented @Retention(RUNTIME) 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;

      the class of the refined qualifier to be applied.
    • when

      Class<? extends Annotation> when
      the qualifier class of the receiver that causes the result qualifier to be applied.
