All Implemented Interfaces:

FIPANames.InteractionProtocol, java.io.Serializable

public class SimpleAchieveREResponder
extends SimpleBehaviour
implements FIPANames.InteractionProtocol

This is a single homogeneous and effective implementation of all the FIPA-Request-like interaction protocols defined by FIPA, that is all those protocols where the initiator sends a single message (i.e. it performs a single communicative act) within the scope of an interaction protocol in order to verify if the RE (Rational Effect) of the communicative act has been achieved or not. Note that this is a simple implementation of the AchieveREResponder. that does not allow to register Behaviour for the Prepare Response and Prepare Result Notification states of the protocol

Constructor and Description
SimpleAchieveREResponder(Agent a, MessageTemplate mt) Constructor of the behaviour that creates a new empty DataStore

Method Summary

Modifier and Type	Method and Description
static MessageTemplate	createMessageTemplate(java.lang.String iprotocol) This static method can be used to set the proper message Template (based on the interaction protocol and the performative) into the constructor of this behaviour.
boolean	done() This method checks whether this behaviour has finished or not.
protected ACLMessage	prepareResponse(ACLMessage request) This method is called when the initiator's message is received that matches the message template passed in the constructor.
protected ACLMessage	prepareResultNotification(ACLMessage request, ACLMessage response) This method is called after the response has been sent and only when one of the folliwing two cases arise: the response was an agree message OR no response message was sent.
void	reset() Reset this behaviour using the same MessageTemplate.
void	reset(MessageTemplate mt) This method allows to change the MessageTemplate that defines what messages this FIPARequestResponder will react to and reset the protocol.

Constructor Detail

SimpleAchieveREResponder

public SimpleAchieveREResponder(Agent a,
                                MessageTemplate mt)

Constructor of the behaviour that creates a new empty DataStore

SimpleAchieveREResponder

public SimpleAchieveREResponder(Agent a,
                                MessageTemplate mt,
                                DataStore store)

Constructor.

Parameters:

a - is the reference to the Agent object

mt - is the MessageTemplate that must be used to match the initiator message. Take care that if mt is null every message is consumed by this protocol.

store - the DataStore for this protocol

Method Detail

createMessageTemplate

public static MessageTemplate createMessageTemplate(java.lang.String iprotocol)

This static method can be used to set the proper message Template (based on the interaction protocol and the performative) into the constructor of this behaviour.

FIPANames.InteractionProtocol

prepareResponse

protected ACLMessage prepareResponse(ACLMessage request)
                              throws NotUnderstoodException,
                                     RefuseException

This method is called when the initiator's message is received that matches the message template passed in the constructor. This default implementation return null which has the effect of sending no reponse. Programmers should override the method in case they need to react to this event.

Parameters:

request - the received message

Returns:

the ACLMessage to be sent as a response (i.e. one of agree, refuse, not-understood, inform. Remind to use the method createReply of the class ACLMessage in order to create a good reply message

Throws:

NotUnderstoodException

RefuseException

See Also:

ACLMessage.createReply()

prepareResultNotification

protected ACLMessage prepareResultNotification(ACLMessage request,
                                               ACLMessage response)
                                        throws FailureException

This method is called after the response has been sent and only when one of the folliwing two cases arise: the response was an agree message OR no response message was sent. This default implementation return null which has the effect of sending no result notification. Programmers should override the method in case they need to react to this event.

Parameters:

request - the received message

response - the previously sent response message

Returns:

the ACLMessage to be sent as a result notification (i.e. one of inform, failure. Remind to use the method createReply of the class ACLMessage in order to create a good reply message

Throws:

FailureException

See Also:

ACLMessage.createReply(), prepareResponse(ACLMessage)

reset

public void reset()

Reset this behaviour using the same MessageTemplate.

Overrides:

reset in class SimpleBehaviour

reset

public void reset(MessageTemplate mt)

This method allows to change the MessageTemplate that defines what messages this FIPARequestResponder will react to and reset the protocol.

done

public boolean done()

This method checks whether this behaviour has finished or not.

Specified by:

done in class Behaviour

Returns:

true if this behaviour has completed its task, false otherwise.
