JADE学习笔记之 一个Agent动态创建另一个Agent

一个Agent如何以程序的方式声称另一个Agent：可以通过以下方式进行创建：

String name = "Alice" ;

        AgentContainer c = getContainerController();

        try {

            AgentController a = c.createNewAgent( name, "Pong", null );

            a.start();

        }

        catch (Exception e){}

其中，createNewAgent方法的第一个参数是要创建的Agent的名称，第二个是Agent的类名，实际使用时要包括他所在的命名空间（包名），第三个参数是要传入的参数的名称。

例子：package jadePrime.acl;

/**

 * Program which creates another Agent and sends

       ------------     it some messages

       comm2.java

 *

 */

 

import jade.core.Agent;

import jade.core.behaviours.*;

import jade.core.AID;

import jade.wrapper.AgentContainer;

import jade.wrapper.AgentController;//这两个是必须要引用的包

import jade.lang.acl.*;

 

 

 

public class Comm2 extends Agent {

       String name = "Alice" ;

       AID alice = new AID( name, AID.ISLOCALNAME );

       protected void setup(){

             

              AgentContainer c=getContainerController();

              System.out.println("find container!");

             

              try{

                     AgentController a=c.createNewAgent(name,"jadePrime.acl.Pong",null);

                     a.start();

                     System.out.println("++++pong has created:"+alice);

                    

              }

              catch (Exception e){

                     System.out.println("Create Agent Error!");

                     addBehaviour(new SimpleBehaviour(this){

                            int n=0;

                            public void action()

                             {

                                   ACLMessage msg = new ACLMessage(ACLMessage.INFORM);

                                   msg.setContent("Message #" + n );

                                   msg.addReceiver(alice);

                                   System.out.println("+++ Sending: " + n);

                                   send(msg);

                                   block( 1000 );

                             }

 

                            public boolean done(){return ++n>3;}

                     });

              }

             

       }

}

当我们创建一个Comm2的Agent时，在控制台上会打印出创建alice成功的消息。
