Class TomP2PDecoderTCP

java.lang.Object
  org.jboss.netty.channel.SimpleChannelUpstreamHandler
      org.jboss.netty.handler.codec.frame.FrameDecoder
          net.tomp2p.message.TomP2PDecoderTCP

All Implemented Interfaces:

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

public class TomP2PDecoderTCP
extends org.jboss.netty.handler.codec.frame.FrameDecoder

The decoder first decodes the header. If this has been successful, then if there is payload, then the payload is decoded. The TomP2P decoder can be used to decode several messages in the same session as long as they are sequential. This class is not thread safe.
