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.

Method Detail

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
