org.jboss.jandex.TypeTarget

org.jboss.jandex.PositionBasedTypeTarget

org.jboss.jandex.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> { ... }
 

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

Method Detail

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.

Specified by:

usage in class TypeTarget

Returns:

the kind of usage of this type target

enclosingTarget

public MethodInfo enclosingTarget()

Description copied from class: TypeTarget

Returns the enclosing target that contains the type referred to by the TypeTarget.target() method.

Overrides:

enclosingTarget in class TypeTarget

Returns:

the enclosing target

asMethodParameterType

public MethodParameterTypeTarget asMethodParameterType()

Description copied from class: TypeTarget

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

Overrides:

asMethodParameterType in class TypeTarget

Returns:

an instance of MethodParameterTypeTarget
