Class AOPInstance

java.lang.Object
  org.jboss.cache.aop.AOPInstance

All Implemented Interfaces:

java.io.Serializable

public class AOPInstance
extends java.lang.Object
implements java.io.Serializable

Wrapper type for cached AOP instances. When an object is looked up or put in TreeCacheAOP, this object will be advised with a CacheInterceptor. The tree cache stores a reference to this object (for example to update the instance variables, etc.). Since this reference need to be transactional but never replicated (the reference is only valid within the VM) this reference is wrapped into an AOPInstance. In addition, this instance also serves as a metadata for TreeCacheAop. E.g., it has a reference count for multiple references and reference FQN.
