Class PojoInstance

java.lang.Object
  org.jboss.cache.pojo.impl.PojoInstance

All Implemented Interfaces:

Serializable

public class PojoInstance
extends Object
implements Serializable

POJO class metadata information. When an object is looked up or put in PojoCache, this object will be advised with a CacheFieldInterceptor. The underlying 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 thus stored into an PojoReference (as a transient field). In addition, this instance also serves as a metadata for PojoCache. E.g., it has a reference counting for multiple references and reference FQN.
