  - ### Method Detail

    - #### opened

          public void opened(Socket socket)

      Description copied from interface: `NetworkTrafficListener`

      Callback method invoked when a connection from a remote client has been accepted.

      The `socket` parameter can be used to extract socket address information of the remote client.

      Specified by:
        `opened` in interface `NetworkTrafficListener`
      Parameters:
        `socket` - the socket associated with the remote client

    - #### incoming

          public void incoming(Socket socket,
                      Buffer bytes)

      Description copied from interface: `NetworkTrafficListener`

      Callback method invoked when bytes sent by a remote client arrived on the server.

      Specified by:
        `incoming` in interface `NetworkTrafficListener`
      Parameters:
        `socket` - the socket associated with the remote client
        `bytes` - the read-only buffer containing the incoming bytes

    - #### outgoing

          public void outgoing(Socket socket,
                      Buffer bytes)

      Description copied from interface: `NetworkTrafficListener`

      Callback method invoked when bytes are sent to a remote client from the server.

      This method is invoked after the bytes have been actually written to the remote client.

      Specified by:
        `outgoing` in interface `NetworkTrafficListener`
      Parameters:
        `socket` - the socket associated with the remote client
        `bytes` - the read-only buffer containing the outgoing bytes

    - #### closed

          public void closed(Socket socket)

      Description copied from interface: `NetworkTrafficListener`

      Callback method invoked when a connection to a remote client has been closed.

      The `socket` parameter is already closed when this method is called, so it cannot be queried for socket address information of the remote client.
      However, the `socket` parameter is the same object passed to `NetworkTrafficListener.opened(Socket)`, so it is possible to map socket information in `NetworkTrafficListener.opened(Socket)` and retrieve it in this method.

      Specified by:
        `closed` in interface `NetworkTrafficListener`
      Parameters:
        `socket` - the (closed) socket associated with the remote client
