Class AnnotationDescriptor<T extends Annotation>

java.lang.Object
  org.hibernate.validator.util.annotationfactory.AnnotationDescriptor<T>

public class AnnotationDescriptor<T extends Annotation>
extends Object

Encapsulates the data you need to create an annotation. In particular, it stores the type of an Annotation instance and the values of its elements. The "elements" we're talking about are the annotation attributes, not its targets (the term "element" is used ambiguously in Java's annotations documentation).
