Examples of org.jboss.aop.InstanceAdvisor

org.jboss.aop.InstanceAdvisor
Holds an object instance's metadata and attached interceptor chain.
The interceptor chain attached to an advised object contains interceptors that are applied to every method execution and field access joinpoint of that object. At startup, the instance interceptor chain is always empty. This chain is specially tailored for per-instance dynamic AOP operations, allowing the addition and removal of interceptors at runtime. The order in which the interceptors are invoked depends on which method was used to add them to the chain (for more information, see {@link #insertInterceptor } and {@link #appendInterceptor}methods).
Notice that every interceptor chain operation provided by an instance advisor affects only the advised object interceptor chain, and hence it will not affect other advised instances, regardless of whether they belong to the same class or not. @author Bill Burke @version $Revision: 68585 $
