Class TypeParameterTypeTarget

All Implemented Interfaces:
AnnotationTarget
Direct Known Subclasses:
TypeParameterBoundTypeTarget

public class TypeParameterTypeTarget extends PositionBasedTypeTarget
Represents a type annotation target which occurs within a type parameter type. This class conveys the zero-based position of the parameter, and the enclosing method or class where it occurs. 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 <@Bar T> void foo(List<T>) { ... }
 

This example would be represented as a TypeParameterTypeTarget with an enclosing target of foo's MethodInfo, and position() would return 0. The "Bar" annotation would appear on the type variable T when invoking the typeParameters() method on MethodInfo

    • usage

      public TypeTarget.Usage usage()
      Description copied from class: TypeTarget
      Returns the kind of usage of this type target. This allows a caller to use a switch statement as opposed to getClass() comparisons.
      Specified by:
      usage in class TypeTarget
      Returns:
      the kind of usage of this type target
    • asTypeParameter

      public TypeParameterTypeTarget asTypeParameter()
      Description copied from class: TypeTarget
      Casts and returns this type target as a TypeParameterTypeTarget. If this type target is not a TypeParameterTypeTarget, then an exception will be thrown.
      Overrides:
      asTypeParameter in class TypeTarget
      Returns:
      an instance of TypeParameterTypeTarget
