使用 Veins 检查 Omnet++ 中的模块析构函数

check module destructor in Omnet++ with Veins

本文关键字:模块 析构函数 Omnet++ Veins 检查 使用      更新时间:2023-10-16

我有一个VANETs项目,我使用veins-2.0-rc2。

在课堂 LinearMobility.cc 我有这个代码,

void LinearMobility::initialize(int stage)
{
  BaseMobility::initialize(stage);
  debugEV << "initializing LinearMobility stage " << stage << endl;
  if (stage == 0)
  {
    move.setSpeed(par("speed").doubleValue());
    acceleration = par("acceleration");
    angle = par("angle");
    angle = fmod(angle,360);
 }
 else if(stage == 1)
 {
    stepTarget = move.getStartPos();
    if(!world->use2D()) 
    {
        opp_warning("This mobility module does not yet support 3 dimensional movement."
                    "Movements will probably be incorrect.");
    }
    if(!world->useTorus()) 
    {
        opp_warning("You are not using a torus (parameter "useTorus" in"
                    "BaseWorldUtility module) playground but this mobility"
                    "module uses WRAP as border policy.");
    }
  }
}

我尝试通过修改类 LinearMobility.cc 将事故事件添加到我的方案中

void LinearMobility::initialize(int stage)
{
  BaseMobility::initialize(stage);
  debugEV << "initializing LinearMobility stage " << stage << endl;
if (stage == 0){
    move.setSpeed(par("speed").doubleValue());
    acceleration = par("acceleration");
    angle = par("angle");
    angle = fmod(angle,360);
    accidentCount = par("accidentCount");
    WATCH(angle);
    startAccidentMsg = 0;
    stopAccidentMsg = 0;
    if (accidentCount > 0) {
                simtime_t accidentStart = par("accidentStart");
                startAccidentMsg = new cMessage("scheduledAccident");
                stopAccidentMsg = new cMessage("scheduledAccidentResolved");
                scheduleAt(simTime() + accidentStart, startAccidentMsg);
            }
}
else if(stage == 1){
    stepTarget = move.getStartPos();
    if(!world->use2D()) {
        opp_warning("This mobility module does not yet support 3 dimensional movement."
                    "Movements will probably be incorrect.");
    }
    if(!world->useTorus()) {
        opp_warning("You are not using a torus (parameter "useTorus" in"
                    "BaseWorldUtility module) playground but this mobility"
                    "module uses WRAP as border policy.");
    }
  }
 }
void LinearMobility::handleSelfMsg(cMessage *msg)
{
   if (msg == startAccidentMsg) {
    
    simtime_t accidentDuration = par("accidentDuration");
    scheduleAt(simTime() + accidentDuration, stopAccidentMsg);
    accidentCount--;
  }
  else if (msg == stopAccidentMsg) {
    
    if (accidentCount > 0) {
        simtime_t accidentInterval = par("accidentInterval");
        scheduleAt(simTime() + accidentInterval, startAccidentMsg);
    }
 }
}

但是我在OMNeT++中遇到了这个问题:

未处置的对象:(cMessage) Scenario.node[0].mobility.scheduledAccidentResolve -- check module destructor

未处置的对象:(cMessage) Scenario.node[0].mobility.scheduledAccident-- check module destructor

未释放的对象: (cMessage) Scenario.node[1].mobility.move -- check module 析构函数未处置的对象:(cMessage) Scenario.node[2].mobility.move -- check module destructor未处置的对象:(cMessage) Scenario.node[3].mobility.move -- check module destructor未处置的对象:(cMessage) Scenario.node[4].mobility.move -- 检查模块析构函数

谁能帮我解决?

这些消息通知您已创建对象,但不会将其删除。它涉及消息:startAccidentMsgstopAccidentMsg,可能还有与移动相关的消息。
解决方案:在方法finish()中添加以下代码:

cancelAndDelete(startAccidentMsg);
cancelAndDelete(stopAccidentMsg);

如果没有finish()方法,只需添加它。
