Class TypeParameterTypeTarget

java.lang.Object
org.jboss.jandex.TypeTarget
org.jboss.jandex.PositionBasedTypeTarget
org.jboss.jandex.TypeParameterTypeTarget
All Implemented Interfaces:
AnnotationTarget
Direct Known Subclasses:
TypeParameterBoundTypeTarget
public class TypeParameterTypeTarget extends PositionBasedTypeTarget
Represents a target of type annotation which occurs within a type parameter. 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> l) { ... }

This example would be represented as a TypeParameterTypeTarget with an enclosing target of the MethodInfo of foo, and position() would be 0.
