问题描述

我正在尝试找到一个很好的示例，说明如何使用Boost序列化内容的这些二进制宽字符版本.我拼凑了一些代码以尝试使其正常运行，但不幸的是，在尝试编译它时，链接器错误使我大吃一惊.

I'm trying to find a good example of how to use these binary wide character versions of boost's serialization stuff. I pieced together some code to try and get it working, but unfortunately I get bombarded with linker errors when trying to compile it.

这是我的代码，以防万一我做错了任何事情:

Here's my code, in case I'm doing anything obviously wrong:

    #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()
    {
        std::vector<const testClass> objectStorage;


        objectStorage.push_back(testClass(1, L"test\0", 9.14f, 6.662f));
        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<<"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;
    }

对于理解错误和解决方法的建议将不胜感激.

Advice on understanding what is wrong and how to resolve it would be greatly appreciated.

推荐答案

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

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

Instead boost/archive/binary_oarchive.hpp and boost/archive/binary_iarchive.hpp will work just fine even for class instances that contain wide character variables!

我希望这些信息对某人有所帮助.
