jade.core.behaviours.WakerBehaviour

This abstract class implements a OneShot task that must be executed only one just after a given timeout is elapsed.

The task is simply the call to the method handleElapsedTimeout() that must be implemented by all subclasses. Notice that the best practice in JADE is when this method just adds a behaviour to the agent class.

All subclasses have available the protected variable myAgent that points to the agent class.

The programmer must use this abstract class in this simple way:

implements a subclass that extends WakerBehaviour. This subclass must implement the method handleElapsedTimeout.
add the subclass to the list of behaviour of this agent by using addBehaviour() method.
the method handleElapsedTimeout must implement the task that will be executed after the timeout is elapsed.
