Class AnnotationInstanceProvider

java.lang.Object

org.jboss.solder.reflection.AnnotationInstanceProvider

public class AnnotationInstanceProvider
extends Object

Provides dynamic annotation creation. If you know the type of the annotation instance to create at development time you should use AnnotationLiteral instead of AnnotationInstanceProvider.

AnnotationInstanceProvider creates a proxy, and will return values as provided when the annotation instance was created. An AnnotationInstanceProvider will cache generated proxy classes.
