Class TCPProtocol

java.lang.Object
  com.voytechs.jnetstream.protocol.layer4.TCPProtocol

All Implemented Interfaces:

DecoderListener

public class TCPProtocol
extends java.lang.Object
implements DecoderListener

This class implements certain higher functions of the TCP protocol. First it monitors all TCP flows which are comming from FlowDecoder, then it tracks at each stream layer for TCP FIN and closing of the socket. It notifies the FlowDecoder that a TCP stream has ended and that it can expire the flow associated with that stream.

Since:

0.2.3
