port - The port on which the registry accepts requests.
adapter - The adapter used by the communicator.
Method Detail

execute

public void execute()
             throws TaskExecutionException

callback

public void callback(Message<?> response)
              throws RemoteException
Invoked to notifies this communicator that the response is now completed and ready to be sent back to the solution. This method is invoked by the remote monitor associated with this communicator.

Specified by:
callback in interface IAsyncOutIn
Parameters:
response - The response message.
Throws:
RemoteException - if a remote exception is occurs.
See Also:
solicitor.Monitor

update

public void update(guarana.util.observer.smart.SmartObservable slot,
                   Object arg)
This method is automatically called by the observable slot to notify the slot has received a message. For all those tasks that can execute with one or more messages in its input slots, this method will add the task to the executable task reporter, so it can be executed. In this case the task execution will consume messages from all input slots.
Please, do not call this method by yourself. Overrides the implementation at Task for performance reasons.

Specified by:
update in interface guarana.util.observer.smart.ISmartObserver
Overrides:
update in class Task
Parameters:
slot - The Slot associated with this task.
arg - THIS PARAMETHER IS NOT USED.
