net.tomp2p.rpc
Class RequestHandlerUDP<K extends FutureResponse>

java.lang.Object
  org.jboss.netty.channel.SimpleChannelHandler
      net.tomp2p.rpc.RequestHandlerUDP<K>

All Implemented Interfaces:

org.jboss.netty.channel.ChannelDownstreamHandler, org.jboss.netty.channel.ChannelHandler, org.jboss.netty.channel.ChannelUpstreamHandler

public class RequestHandlerUDP<K extends FutureResponse>
extends org.jboss.netty.channel.SimpleChannelHandler

Is able to send UDP messages (as a request) and processes incoming replies. It is important that this class handles close() because if we shutdown the connections, the we need to notify the futures. In case of error set the peer to offline. A similar class is RequestHandlerTCP, which is used for TCP.
