com.sun.enterprise.mgmt.transport.jxta.JxtaPipeManagerWrapper

All Implemented Interfaces:

MessageSender, MulticastMessageSender, ShoalMessageSender, java.util.EventListener, net.jxta.pipe.PipeMsgListener

public class JxtaPipeManagerWrapper
extends AbstractMultiMessageSender
implements net.jxta.pipe.PipeMsgListener

This class wraps JxtaPipeManager and extends AbstractMultiMessageSender which supports both MulticastMessageSender and MessageSender transport layer This stores and caches JxtaPipeManager according to Message's type This implements Jxta's PipeMsgListener, receives Jxta's PipeMsgEvent, parses Jxta's message, converts it into Message and forwards it to NetworkManager
