Class EmptyTypeTarget

java.lang.Object

org.jboss.jandex.TypeTarget

org.jboss.jandex.EmptyTypeTarget

All Implemented Interfaces:

AnnotationTarget

public class EmptyTypeTarget
extends TypeTarget

Represents a target of type annotation which occurs directly on a field type, a method return type, or a method receiver type. This class conveys the enclosing field or method, and if a method, also differentiates between the receiver and return value. 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 List<@Bar T> foo() { ... }

This example would be represented as an EmptyTypeTarget with an enclosing target of the MethodInfo of foo, and isReceiver() would be false.

Method Details

isReceiver

public boolean isReceiver()

Returns whether the annotated type occurs within a method receiver (the this reference the method receives). It will return false if the type occurs in a method return type or in a field type.

Returns:

true if the annotated type occurs within a method receiver type, otherwise false

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

asEmpty

public EmptyTypeTarget asEmpty()

Overrides:
