Class AnnotationImpl

org.apache.juneau.annotation.AnnotationImpl

All Implemented Interfaces:

Annotation

Direct Known Subclasses:

TargetedAnnotationImpl

public class AnnotationImpl
extends Object
implements Annotation

A concrete implementation of an annotation.

Follows the standard Java conventions for equality and hashcode calculation for annotations. Equivalent annotations defined programmatically and declaratively should match for equality and hashcode calculation.

For performance reasons, the hashcode is calculated one time and cached at the end of object creation. Constructors must call the postConstruct() method after all fields have been set to trigger this calculation.
