Examples of org.jboss.aop.ClassAdvisor

org.jboss.aop.ClassAdvisor
Advises a class and provides access to the class's aspect chain. Each advisable class has an associated Advisor instance. References methods using int IDs rather than the actual instances for optimal performance. Provides ability to invoke methods on an advised object without advice (see Advisor.invokeWithoutAdvisement()). @author Bill Burke @version $Revision: 64305 $
