Class EmptyTypeTarget

  • All Implemented Interfaces:
    AnnotationTarget

    public class EmptyTypeTarget
    extends TypeTarget
    Represents a type annotation target which occurs directly on a field type, a method return type, or a method receiver type. This class conveys the enclosing field or method, and if a method, also differentiates between the receiver and return value. Since type targets can appear at any depth of the type tree at this location, the corresponding type reference is also included.

    Consider the following example involving a type target using the "Bar" annotation:

     public List<@Bar T> foo { return foo; }
     
    This example would be represented as an EmptyTypeTarget with an enclosing target of Foo's MethodInfo, and isReceiver would return false.

      • usage

        public final TypeTarget.Usage usage()
        Description copied from class: TypeTarget
