Examples of org.jboss.aop.AspectManager

org.jboss.aop.AspectManager
This singleton class manages all pointcuts and metadata. Coders can access it via the AspectManager.instance() method.
It is also the middle man between the ClassLoader and the actual class instrumentation as well.
App Developers that want to create and apply, interceptors, pointcuts, or metadata at runtime can also use this object to do that. @author Bill Burke @author adrian@jboss.org @version $Revision: 84460 $
