我需要使用FIPA-ContractNet-Protocol将CFP（每秒）发送到代理列表（每五秒钟刷新一次，要求发送）。
我正在创建一个TickerBehaviour，并将对addBehaviour（new ContractNetInitiator（myAgent，msg））的调用放入onTick（）方法中。
public class MainAgent extends Agent {
private Vector<AID> agents;
ACLMessage msg;
private int nResponders;
protected void setup() {
agents = new Vector<AID>();
elementosTotales = new ArrayList<Elemento>();
ambienteGlobal = new Ambiente();
msg = new ACLMessage(ACLMessage.CFP);
addBehaviour(new SearchAgents(this, 5000));
addBehaviour(new SendMessage(this, 1000));
}
}
private class SearchAgents extends TickerBehaviour {
public SearchAgents(Agent a, long period) {
super(a, period);
agents = new Vector<AID>();
}
public void onTick() {
DFAgentDescription plantilla = new DFAgentDescription();
ServiceDescription sd = new ServiceDescription();
sd.setType("Enviar-Ambiente");// Busca los servicios que envian el ambiente
plantilla.addServices(sd);
try {
DFAgentDescription[] resultado = DFService.search(myAgent, plantilla);
agents.clear();
for (int i = 0; i < resultado.length; ++i) {
agents.addElement(resultado[i].getName());
}
}
catch (FIPAException fe) {
fe.printStackTrace();
}
}
}
private class SendMessage extends TickerBehaviour {
public SendMessage(Agent a, long period) {
super(a, period);
}
@Override
protected void onTick() {
msg.clearAllReceiver();
if (agents.size() > 0) {
nResponders = agents.size();//
System.out.println(
getLocalName() + ": sending message to " + nResponders + " agents.");
for (int i = 0; i < agents.size(); ++i) {
msg.addReceiver(agents.get(i));
}
msg.setProtocol(FIPANames.InteractionProtocol.FIPA_CONTRACT_NET);
msg.setContent("mandar-ambiente");
addBehaviour(new Comunicator(myAgent, msg));
} else {
System.out.println(getLocalName() + ": No available agents .");
}
}
}
class Comunicator extends ContractNetInitiator {
public int onEnd() {
return super.onEnd();
}
public Comunicator(Agent a, ACLMessage msg) {
super(a, msg);
}
//METHODS WITH CODE IN THEY
protected void handleRefuse(ACLMessage refuse) {
}
protected void handleFailure(ACLMessage failure) {
}
protected void handleAllResponses(Vector responses, Vector acceptances) {
}
}
行为通信器已多次创建，但消息已中断。
