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

Question

我想找到一個很好的例子，說明如何使用這些boost的序列化的東西的二進制寬字符版本。我拼湊了一些代碼來試着讓它工作，但不幸的是，當我試圖編譯它時，我遇到了鏈接器錯誤。

這裏是我的代碼，如果我做任何事情顯然是錯誤的：

#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; 
     }

      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));

       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 
     {

     myFileInput.close();

這裏是錯誤的：在理解什麼是錯的，以及如何解決這將是

諮詢不勝感激。

Answer 1

事實證明，boost/archive/binary_woarchive.hpp和boost/archive/binary_wiarchive.hpp是多餘的。

而不是boost/archive/binary_oarchive.hpp和boost/archive/binary_iarchive.hpp即使對於包含寬字符變量的類實例也能正常工作！

我希望這些信息可以幫助某人。
