Class ClientNode

java.lang.Object

org.oddjob.jmx.client.ClientNode

All Implemented Interfaces:

java.lang.reflect.InvocationHandler, Exportable

public class ClientNode
extends java.lang.Object
implements java.lang.reflect.InvocationHandler, Exportable

The client side representation of a remote node. A proxy is used to implement a mirror of the remote node. This class is the invocation handler for that proxy. This class is never accessed directly by client code.

On creation the client node will lookup up various things on the server on configure the proxy, register for notifications and start a resync.

It is possible that a serverside node has bean created and destroyed and that the client hasn't caught up. In this case dead placeholder nodes are put in the tree. They should be short lived, and removed when the client catches up with the notifications.
