c++ - boost/archive/binary_woarchive.hpp 和/或 boost/archive/binary_wiarchive.hpp 的序列化示例？

Question

我试图找到一个很好的例子来说明如何使用这些二进制宽字符版本的 boost 序列化内容。我拼凑了一些代码来尝试让它工作，但不幸的是，我在尝试编译它时遇到了链接器错误的轰炸。

这是我的代码，以防我做任何明显错误的事情:

    #include <cstdlib>
    #include <iostream>
    #include <fstream>
    #include <string>
    #include <vector>

    #include <boost/archive/binary_woarchive.hpp>
    #include <boost/archive/binary_wiarchive.hpp>

    class testClass
    {
    public:
        testClass()
        {
        }
        testClass(const int intInput, const std::wstring stringInput, const float floatInput01, const float floatInput02)
        {
            ourString = stringInput;
            testInt = intInput;
            testFloat01 = floatInput01;
            testFloat02 = floatInput02;
        }
        ~testClass()
        {}

        int testInt;
        std::wstring ourString;
        float testFloat01;
        float testFloat02;

        int ReturnTestInt()
        {
            return testInt;
        }

        float RandomStuff()
        {
            float alpha01 = 26.9;
            alpha01 /= 2;
            return alpha01;
        }

    private:
        friend class boost::serialization::access;
        template<class Archive>
        void serialize(Archive &ar, const unsigned int version)
        {
            ar &testInt;
            ar &ourString;
            ar &testFloat01;
            ar &testFloat02;
        }
    };

    int main()

        objectStorage.push_back(testClass(2, L"temp\0", 0.29f, 3.331f));
        objectStorage.push_back(testClass(3, L"then\0", 2.47f, 8.888f));


        testClass testReceivedObject;
        std::ifstream::pos_type size;

        std::wofstream myFile;
        boost::archive::binary_woarchive outputArchive(myFile);
        myFile.open("Example.dat", std::ios::out | std::ios::binary);

        if(myFile.is_open() && myFile.good())
        {
            std::cout<<"File opening successfully completed."<<std::endl;
            unsigned int storageSize = objectStorage.size();

            myFile.write(reinterpret_cast<wchar_t*>(&storageSize), (sizeof(unsigned int)));

            for(int i = 0; i < objectStorage.size(); i++)
            {
                outputArchive<<objectStorage[i];
            }
            /*

            myFile.write(reinterpret_cast<char*>(&objectStorage[2]), (sizeof(testClass)));
        */
        }
        else
        {
            std::cout<<"File opening NOT successfully completed."<<std::endl;
        }
        myFile.close();

        std::wifstream myFileInput;
        boost::archive::binary_wiarchive inputArchive(myFileInput);
        myFileInput.open("Example.dat", std::ios::in | std::ios::binary | std::ios::ate);

        if(myFileInput.is_open() && myFileInput.good())
        {
            std::cout<<"File opening successfully completed.  Again."<<std::endl;

            std::cout<<"READ:"<<std::endl;
            size = myFileInput.tellg();
            unsigned int numberOfObjects = 0;
            myFileInput.seekg(0, std::ios::beg);            
myFileInput.read(reinterpret_cast<wchar_t *>(&numberOfObjects), sizeof(unsigned int));
            for(int i = 0; i < numberOfObjects; i++)
            {
                objectStorage.resize(objectStorage.size()+1);
                inputArchive>>objectStorage[i];
                //myFileInput.read(reinterpret_cast<wchar_t *>(&objectStorage[i])/*(&testReceivedObject)*/, sizeof(testClass));
            }
            std::cout<<std::endl<<"END."<<std::endl;
        }
        else
        {
            std::cout<<"Something has gone disasterously wrong."<<std::endl;
        }
        myFileInput.close();

        for(int i = 0; i < objectStorage.size(); i++)
        {
            std::wcout<<objectStorage[i].ourString<<std::endl;
        }
        return 0;
    }

错误如下:

非常感谢您提供有关了解问题所在以及如何解决问题的建议。

Answer 1

事实证明，boost/archive/binary_woarchive.hpp 和 boost/archive/binary_wiarchive.hpp 是多余的。

相反，boost/archive/binary_oarchive.hpp 和 boost/archive/binary_iarchive.hpp 即使对于包含宽字符变量的类实例也能正常工作!

我希望这些信息对某人有所帮助。
