将矢量地图写入 Omnetpp 中的文件

Question

我在将矢量图写入文件时遇到问题。我想知道 wsmdata 中的详细值。我知道为了访问详细信息，我需要使用运算符重载，例如“std::ostream& operator

以下是部分代码： .h 文件： 使用 std::map;

typedef std::vector<WaveShortMessage*> WaveShortMessages;
std::map<long,WaveShortMessages>    receivedWarningMap;

.cc 文件：

// add warning message to received messages storage
 receivedWarningMap[wsm->getTreeId()].push_back(wsm->dup());
std::cout<<"Wsm dup() values/ receivedWarningMap="<<wsm->dup()<<endl;
std::ofstream tracefile;
tracefile.clear();
tracefile.open("traceFile1.txt", std::ios_base::app);
for (UINT i = 0; i < receivedWarningMap[wsm->getTreeId()].size(); i++)
        {
            std::cout << receivedWarningMap[wsm->getTreeId()][i] << std::endl;

            EV<< "MyID="<<getMyID()<< "Recepient ID"<<wsm->getRecipientAddress()<<"Neighbor ID="<< wsm->getSenderAddress()<< std::endl;

} 跟踪文件.close();

Answer 1

首先为你的类WaveShortMessage定义运算符<<，例如这样：

std::ostream & operator<<(std::ostream &os, WaveShortMessage * wsm) {
    os << "Recepient ID=" << wsm->getRecipientAddress() << "; ";
    os << "Neighbor ID=" << wsm->getSenderAddress() << "; ";
    // and any other fields of this class
    //...
    return os;
}

然后使用以下代码将地图写入文本文件：

// remember to add this two includes at the beginning:
// #include <fstream>
// #include <sstream> 

std::ofstream logFile;
logFile.open("log.txt"); // if exists it will be overwritten 
std::stringstream ss;
for (auto it = receivedWarningMap.begin(); it != receivedWarningMap.end(); ++it) {
    ss << "id=" << static_cast<int>(it->first) << "; wsms=";
    for (auto it2 : it->second) {
        ss << it2 << "; ";
    }
    ss << endl;
}
logFile << ss.str();
logFile.close();
