连接多个消息内容时出错 omnet++

Question

我有这段代码，我从两个进程块（Hey.cc 和 See.cc）的句柄消息中获取消息并将其组合成一条新消息（在 There.cc 中）但是好像不行请帮忙

Hey.cc

#include "Hey.h"

Define_Module(Hey);

void Hey::initialize()
{
    // TODO - Generated method body
    cMessage *mmsg = new cMessage("hello");
    send(mmsg,"hello");
}

void Hey::handleMessage(cMessage *msg)
{
    // TODO - Generated method body
}

和See.cc

#include "See.h"

Define_Module(See);

void See::initialize()
{
    // TODO - Generated method body
    cMessage *smsg = new cMessage("hi");
    send(smsg,"tempexit");
}

void See::handleMessage(cMessage *msg)
{
    // TODO - Generated method body
}

和There.cc

#include "There.h"
#include "See.h"
#include "Hey.h"
#include <string>

Define_Module(There);

void There::initialize()
{
    // TODO - Generated method body
}

void There::handleMessage(cMessage *msg)
{
    cMessage *smsg = new cMessage("hi");    // supposed to be from See.cc
    cMessage *mmsg = new cMessage("hello"); // supposed to be from Hey.cc
    cMessage strNew = *smsg;
    cMessage sstrNew = *mmsg;
    cMessage rNew = strNew + sstrNew ;

    EV << rNew ;
}

Answer 1

send方法的第二个参数应该是the name of gate或指向cGate对象的指针。 Hey.ned是否包含hello输出门，See.ned是否包含tempexit门？
Class cMessage 没有 operator+ 所以一个不能添加两个 cMessage.顺便问一下：您对此次行动的结果有何期待？如果封装消息，应该使用encapsulate().
