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
