Class AnnotationLiteral<T extends java.lang.annotation.Annotation>

java.lang.Object

org.glassfish.hk2.api.AnnotationLiteral<T>

Type Parameters:

T - the annotation type

All Implemented Interfaces:

java.io.Serializable, java.lang.annotation.Annotation

Direct Known Subclasses:

NamedImpl, RunLevelServiceUtilities.RunLevelImpl, ServiceLocatorUtilities.ImmediateImpl, ServiceLocatorUtilities.InheritableThreadImpl, ServiceLocatorUtilities.PerLookupImpl, ServiceLocatorUtilities.PerThreadImpl, ServiceLocatorUtilities.SingletonImpl, UnqualifiedImpl

public abstract class AnnotationLiteral<T extends java.lang.annotation.Annotation>
extends java.lang.Object
implements java.lang.annotation.Annotation, java.io.Serializable

Supports inline instantiation of annotation type instances.

An instance of an annotation type may be obtained by subclassing AnnotationLiteral.

 public abstract class PayByQualifier 
       extends AnnotationLiteral<PayBy>
       implements PayBy {}
 

An extension of AnnotationLiteral must do two things:

1. Must have the target annotation as its generic type
2. Must implement the target type

In particular, in-line anonymous extensions of AnnotationLiteral will not work because in-line anonymous extensions of AnnotationLiteral cannot implement the target annotation
