Examples of org.jboss.aop.Advised

org.jboss.aop.Advised
Interface implemented by all classes or interfaces that are AOP enabled (those are also known as advised classes/interfaces).
In other words, every class that is weaved by JBoss AOP automatically implements this interface, which allows the class and instance advisor retrieval. @author Bill Burke @version $Revision: 68585 $
