如何在omnet++中显示特定轮次的结果？

simple Sender
{
    parameters:
        int numRoundsToDisplay;
}

simple Receiver
{
}

channel channel
{
    datarate = 10Mbps;
}

network MyNetwork
{
    submodules:
        sender: Sender {
            parameters:
                numRoundsToDisplay = 3;
        }
        receiver: Receiver {
        }
    connections:
        sender.out --> channel --> receiver.in;
}

void Sender::initialize()
{
    round = 0;
    numRoundsToDisplay = par("numRoundsToDisplay").intValue();
}

void Sender::handleMessage(cMessage *msg)
{
    if (round < numRoundsToDisplay) {
        // 这里可以发送数据或执行其他操作
        send(msg, "out");

        // 增加轮次计数器
        round++;

        // 打印或记录结果
        EV << "Round " << round << " completed.
";
    } else {
        // 如果达到了指定的轮次，停止发送数据
        cancelAndDelete(msg);
    }
}
