      extended by org.openejb.core.ivm.EjbObjectProxyHandler
          extended by org.openejb.core.entity.EntityEjbObjectHandler
All Implemented Interfaces:
java.io.Serializable, InvocationHandler

public class EntityEjbObjectHandler
extends EjbObjectProxyHandler

This InvocationHandler and its proxy are serializable and can be used by HomeHandle, Handle, and MetaData to persist and revive handles. It maintains its original client identity which allows the container to be more discerning about allowing the revieed proxy to be used. See StatefulContaer manager for more details.

Method Detail

getRegistryId

public static java.lang.Object getRegistryId(java.lang.Object primKey,
                                             java.lang.Object deployId,
                                             Container contnr)

getRegistryId

public java.lang.Object getRegistryId()
The Registry id is a logical identifier that is used as a key when placing EjbObjectProxyHanlders into the BaseEjbProxyHanlder's liveHandleRegistry. EjbObjectProxyHanlders that represent the same bean identity (keyed by the registry id) will be stored together so that they can be removed together when the BaseEjbProxyHandler.invalidateAllHandlers is invoked. This method is implemented by the subclasses to return an id that logically identifies bean identity for a specific deployment id and container. The EntityEjbObjectHandler overrides this method to return a compound key composed of the bean's primary key, deployment id, and container id. This uniquely identifies the bean identity that is proxied by this handler.

getPrimaryKey

protected java.lang.Object getPrimaryKey(java.lang.reflect.Method method,
                                         java.lang.Object[] args,

                                  throws java.lang.Throwable
Specified by:
getPrimaryKey in class EjbObjectProxyHandler

                                       java.lang.Object[] args,
                                       java.lang.Object proxy)
                                throws java.lang.Throwable
