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

23 Aug 2008


      This is fine for most of the cases.
But suppose I want to pass serialized stream over a network and at the other
end I want to validate each datatype before deserializing it then how to do
it?
Can I use typeinfo somehow?

Thanks,
Sameer

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 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
