Class MessageLogger

java.lang.Object
  net.tomp2p.connection.MessageLogger

All Implemented Interfaces:

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

@ChannelHandler.Sharable
public class MessageLogger
extends Object
implements org.jboss.netty.channel.ChannelUpstreamHandler

Prints the received message to a gzip encoded file. We omit to also store the send message because it will be the same as the received:

 peer A -> messsage request -> peer B
 peer B -> message reply -> peer A
 
 peer A (send request)
 peer B (receive request) -> will be logged
 peer B (send reply)
 peer A (receive reply) -> will be logged
