    • request

      public Object request()
      Description copied from interface: ConnectionServer

      Receives a request from a client. This will block until the client calls its request(Object) method. Implementations may make this ALTable.

      After this method has returned, the server should call one of the reply methods. Performing any external process synchronization between these method calls could be potentially hazardous and could lead to deadlock.

      Specified by:
      request in interface ConnectionServer
      Returns:
      the Object sent by the client.
    • reply

      public void reply(Object data)
      Description copied from interface: ConnectionServer

      Sends some data back to the client after a request has been received but keeps the connection open. After calling this method, the server should call recieve() to receive a further request.

      A call to this method is equivalent to a call to reply(Object, boolean) with the boolean set to false.

      Specified by:
      reply in interface ConnectionServer
      Parameters:
      data - the data to send to the client.
    • reply

      public void reply(Object data, boolean close)
      Description copied from interface: ConnectionServer

      Sends some data back to the client after a request has been received. The boolean close parameter indicates whether the connection should be closed after this reply has been sent.

      This method should not block.

      Specified by:
      reply in interface ConnectionServer
      Parameters:
      data - the data to send back to client.
      close - boolean that should be true iff the connection should be dropped after the reply has been sent.
    • replyAndClose

      public void replyAndClose(Object data)
      Description copied from interface: ConnectionServer

      Sends some data back to the client and closes the connection.

      A call to this method is equivalent to a call to reply(Object, boolean) with the boolean set to true.

      Specified by:
      replyAndClose in interface ConnectionServer
      Parameters:
      data - the data to send back to client.
    • duplicate

      public SharedConnectionServer duplicate()
      Description copied from interface: SharedConnectionServer

      Creates a duplicate copy of the connection end.

      Specified by:
      duplicate in interface SharedConnectionServer
      Returns:
      the duplicate SharedConnectionServer object.
