cDelayChannel * channel = check_and_cast<cDelayChannel*>(gate("out1")->getChannel());
    delay1 = channel->getDelay().dbl();


    cMessage *msg = new cMessage("tictocMsg");
         cMessage *ww ; ww=msg;

         send(msg, "out1");
         cMessage *copy = (cMessage *) msg->dup();send(copy, "out2");

我的问题是如何使用延迟 computer0.out - ＆gt; {延迟= 100ms ; } - ＆gt; computer1.in; 在.cc文件中。在源文件中，我有两个变量delay1和delay2。我想在delay1和delay2变量中移动延迟值（100）。怎么做？

Answer 1

在OMNeT ++ 4.6中读取通道延迟值的示例。
NED文件：

// File: network.ned
simple computer
{
    parameters:
    gates:
        input in1;
        output out1;
        input in2;
        output out2;
}

network Network
{
    @display("bgb=538,302");
    submodules:
        A: computer {
            @display("p=30,88");
        }
        B: computer {
            @display("p=344,96");
        }
        C: computer {
            @display("p=209,199");
        }
    connections:
        A.out1 --> {  delay = 100ms; } --> B.in1;
        B.out1 --> {  delay = 100ms; } --> A.in1;
        A.out2 --> {  delay = 200ms; } --> C.in1;
        C.out1 --> {  delay = 200ms; } --> A.in2;
        C.out2 --> {  delay = 300ms; } --> B.in2;
        B.out2 --> {  delay = 300ms; } --> C.in2;
}

源文件：

// file: computer.cc
#include <string.h>
#include <omnetpp.h>
#include <string>

double delay1;

class computer: public cSimpleModule {
public:

    virtual void initialize();
    virtual void handleMessage(cMessage *msg);
};

Define_Module(computer);

void computer::initialize() {
    cDelayChannel * channel = check_and_cast<cDelayChannel*>(gate("out1")->getChannel());
    delay1 = channel->getDelay().dbl();
    EV << "delay = " << delay1 << std::endl;
    // other operations...
}

void computer::handleMessage(cMessage *msg) {
}

omnetpp.ini文件：

[General]
network = Network

上面的cc文件是使用OMNeT++ 4.6为Windows编译的。这是启动模拟后的日志：

** Initializing network
Initializing module Network, stage 0
Network.A: Initializing module Network.A, stage 0
Network.A: delay = 0.1
Network.B: Initializing module Network.B, stage 0
Network.B: delay = 0.1
Network.C: Initializing module Network.C, stage 0
Network.C: delay = 0.2

如何在源文件omnet ++中使用延迟
