如何使用JADE在另一个代理中添加来自多个代理的消息（整数值）

Question

I have the following requirement in JADE. I have to create multiple agents whose task is to generate random numbers. Another receiver agent collects all the random numbers generated and sums them up to make a decision. This is the sender agent class extends tickerbehaviour and its tick onTick method is as follows

    protected void onTick()
            {
                ACLMessage msg_LoadDetails = new ACLMessage(ACLMessage.INFORM);
                msg_LoadDetails.addReceiver(new AID("LoadCoordinator", AID.ISLOCALNAME));
                msg_LoadDetails.setContent(String.valueOf(getLoad()));
                LoadConv.send(msg_LoadDetails);
                //load = (int)(Math.random()*1000+1);
            }

The receiver class extend cyclic behaviour and its action method is as follows

public void action()
    {
        ACLMessage msg_IncomingLoadDetails = LoadCoordinator.receive();
        if(msg_IncomingLoadDetails!=null)
        totalLoad = Integer.parseInt(msg_IncomingLoadDetails.getContent());

        if(totalLoad>500)
        {actioncommand = "off";}
        else
        {actioncommand = "on";}

        System.out.println("The current load is:" +totalLoad+ "; the load will be switched " +actioncommand);
        block();
    }

The issue here is that the received values are just for one agent which i create (from console). I want to receive values for all created agents. Does this require me create an array of agents? How do i read values from many agent messages? Could some one please help with the code to do so as I am new to JAVA and JADE?

Answer 1

I tested your code and receiver agent gets message from all sender agents.

I have some questions and remarks:

1. How often sender agents should send their number? Only once, or cyclically, after given time?

2. Your receiver agent doesn't sum received values, he always compares last received value.

3. Better use this structure for logic, after receiving message:

    if (msg_IncomingLoadDetails != null) { // your logic } else { block(); } 

   it can help to prevent some problems like NullPointerException
