- public abstract class FipaQueryResponderBehaviour
- extends SimpleBehaviour
Behaviour class for fipa-query Responder
role. This abstract class implements the fipa-query interaction
protocol. The behaviour is cyclic so it remains active forever.
Its usage is the following: A class must be instantiated that
extends this one. This new class must implement the method
handleQueryMessage(). The instantiated class must then be
added to the Agent object by using the method
Agent.addBehaviour()
