Hi all,

has anyone ever used the versioning mechanism of the serialization library together with template classes?

What I want to do is something like:

   class TemplateA
   {
   public:
      TemplateA();

public:
      ...
   //Serialization stuff
   private:
      friend class boost::serialization::access;

      template<class Archive>
      void save(Archive & ar, const unsigned int /*version*/) const
      {
         ar & boost::serialization::make_nvp("HighValue",m_high)
            & boost::serialization::make_nvp("NewData",m_newData);
      }

      template<class Archive>
      void load(Archive & ar, const unsigned int version)
      {
         ar & boost::serialization::make_nvp("HighValue",m_high);

         if (version > 0)
         {
            ar & boost::serialization::make_nvp("NewData",m_newData);
         }
      }

BOOST_SERIALIZATION_SPLIT_MEMBER();

   private:
      T        m_high;
      T        m_newData;
   }; // class TemplateA

BOOST_CLASS_VERSION(TemplateA, 1);

The above won't compile for sure, but I'm looking for a way to use the versioning without having

to specialize it for each type T which I'm going to use this class with.

Best regards
