SocketProxy, ThreadProxy

public abstract class Proxy
extends Node

This class is used to represent other nodes at a node, so that these nodes are able to connect to the node. A Proxy should establish a connection to the Endpoint of the node that is represented by this proxy. So all protocol specific implementation for connections between nodes must be realized in an pair of Endpoint and Proxy. This class has to be extended by all Proxies that are used to provide a connection to a remote node via the Node interface.
