Class MethodParameterTypeTarget

All Implemented Interfaces:
AnnotationTarget
public class MethodParameterTypeTarget extends PositionBasedTypeTarget
Represents a type annotation target which occurs within a method parameter type. This class conveys the enclosing method and the zero-based position of the parameter. 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 void foo(List<@Bar T> l) { ... }

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