Class AnnotationProxyFactory

java.lang.Object
  net.sf.ehcache.pool.sizeof.filter.AnnotationProxyFactory

public final class AnnotationProxyFactory
extends Object

Allows you to transform the type of your custom annotation to a reference annotation type. It can come handy when you want to allow the consumers of your library not to depend on your API because of the annotations, still allowing them to use the original annotation methods. Example : //getting a custom annotation from a class my.Annotation customAnnotation = klazz.getAnnotation(my.Annotation.class); //if this annotation is "similar" (duck-typing, same methods) to the reference one, I can get a proxy to it, whose type is the reference annotation ehcache.Annotation annotation = AnnotationProxyFactory.getAnnotationProxy(customAnnotation, ehcache.Annotation.class); //so my library can apply the behavior when the default annotation is used
