Re: [Boost-users] boost serialization and datatype mismatch

The easy way is to use:

    template<class Archive>
    void serialize(Archive & ar, const unsigned int file_version)
   {
       ar & tmpMap;
       ar & a;
       ar & d;
       ar & stringList;
   }

then input/output are always insync.

  Hi,

     How to validate datatype before it gets deserialized?
  e.g.
  struct Abc 
  {
    
      std::map<string,string> tmpMap;
      int a;
      float d;
      std::list<string> stringList;

      void serialize(boost::archive::polymorphic_oarchive & ar, const unsigned int file_version)
     {
         ar & tmpMap;
         ar & a;
         ar & d;
         ar & stringList;
     }
       void serialize(boost::archive::polymorphic_iarchive & ar, const unsigned int file_version)
      {
        /////////////////////////////////////////////////////////////////////
        /* Now the right thing to do over here is
         ar & tmpMap;
         ar & a;
         ar & d;
         ar & stringList;
        */
         ///////////////////////////////////////////////////////////////////////
        //But instead, if by mistake user writes something like  
         ar & a;
         ar & d;
         ar & stringList;
         ar & tmpMap;
       /* 
           So how to handle such problem?
           Can I validate data somehow before it gets deserialized?
           On some platforms like SuSE linux I have observed that such thing doesn't throw exception and we get SEGV. 
       */       
      }
        
  };

  Thanks,
  Sameer
