    • send

      public void send(Object reply, boolean is_exception)
      Description copied from interface: Response
      Sends a response, usually called from a thread spawned by RequestHandler.handle(Message,Response)
      Specified by:
      send in interface Response
      Parameters:
      reply - The reply to be sent back, ie. as result to a synchronous RPC. Can be null, e.g. when the method has a void return type.
      is_exception - If RequestHandler.handle(Message,Response) threw an exception, it must be caught, returned as the reply and is_exception must be true. If reply is a regular object, is_exception is false

    • send

      public void send(Message reply, boolean is_exception)
      Description copied from interface: Response
      Similar to Response.send(Object,boolean), but passes a message instead of an object. The message needs to contain the marshalled response, so message creation, setting of flags and marshalling is the responsibility of the caller.

      The reason for this additional method is to give the caller more control over the response message.

      This method may be removed, should we find that it's not really needed

      Specified by:
      send in interface Response
      Parameters:
      reply - The reply message
      is_exception - Whether the payload of this message is an exception or a real reply object
