public class TCP extends BasicTCP
TCP based protocol. Creates a server socket, which gives us the local address of this group member. For each accept() on the server socket, a new thread is created that listens on the socket. For each outgoing message m, if m.dest is in the outgoing hash table, the associated socket will be reused to send message, otherwise a new socket is created and put in the hash table. When a socket connection breaks or a member is removed from the group, the corresponding items in the incoming and outgoing hash tables will be removed as well.

This functionality is in TcpServer, which is used by TCP. TCP sends messages using ct.send() and registers with the connection table to receive all incoming messages.

    • setSocketFactory

      public void setSocketFactory(SocketFactory factory)
      Description copied from class: Protocol
      Sets a SocketFactory. Socket factories are typically provided by the transport (TP)
      Overrides:
      setSocketFactory in class TP
      Parameters:
      factory -

    • send

      public void send(Address dest, byte[] data, int offset, int length) throws Exception
      Specified by:
      send in class BasicTCP
      Throws:
      Exception

    • retainAll

      public void retainAll(Collection<Address> members)
      Specified by:
      retainAll in class BasicTCP

    • start

      public void start() throws Exception
      Description copied from class: TP
      Creates the unicast and multicast sockets and starts the unicast and multicast receiver threads
      Specified by:
      start in interface Lifecycle
      Overrides:
      start in class TP
      Throws:
      Exception - Thrown if protocol cannot be started successfully. This will cause the ProtocolStack to fail, so JChannel.connect(String) will throw an exception

      Description copied from class: Protocol
      Called on a JChannel.disconnect(); stops work (e.g. by closing multicast socket). Will be called from top to bottom.
      Specified by:
      stop in interface Lifecycle
      Overrides:
      stop in class TP
