    • TcpConnectionSupport

      public TcpConnectionSupport(Socket socket, boolean server, boolean lookupHost, @Nullable ApplicationEventPublisher applicationEventPublisher, @Nullable String connectionFactoryName)
      Create a TcpConnectionSupport object and publishes a TcpConnectionOpenEvent, if an event publisher is provided.
      Parameters:
      socket - the underlying socket.
      server - true if this connection is a server connection
      lookupHost - true if reverse lookup of the host name should be performed, otherwise, the ip address will be used for identification purposes.
      applicationEventPublisher - the publisher to which open, close and exception events will be sent; may be null if event publishing is not required.
      connectionFactoryName - the name of the connection factory creating this connection; used during event publishing, may be null, in which case "unknown" will be used.
