All Implemented Interfaces:

AnnotationTarget

public class TypeParameterBoundTypeTarget
extends TypeParameterTypeTarget

Represents a type annotation target which occurs within a bound of type parameter type. This class conveys the zero-based position of the parameter, the zeo-based position of the bound, and finally, 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 <T extends Number & @Bar Serializable> void foo(List<T>) { ... }
 

This example would be represented as a TypeParameterBoundTypeTarget with an enclosing target of foo's MethodInfo, a position() value of "0" and a boundPosition() value of "1". The "Bar" annotation would appear on the type "Serializable" in the bound list of T, on the first type parameter.

Method Detail

boundPosition

public final int boundPosition()

Returns the index of the bound this type annotation is within.

Returns:

the index of the bound this type annotation is within

usage

public final 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.

Overrides:

usage in class TypeParameterTypeTarget

Returns:

the kind of usage of this type target

asTypeParameterBound

public TypeParameterBoundTypeTarget asTypeParameterBound()

Description copied from class: TypeTarget

Casts and returns this type target as a TypeParameterBoundTypeTarget. If this type target is not a TypeParameterBoundTypeTarget, then an exception will be thrown.

Overrides:

asTypeParameterBound in class TypeTarget

Returns:

an instance of TypeParameterBoundTypeTarget
