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 On Fri, Aug 22, 2008 at 11:47 PM, Robert Ramey <ramey@rrsd.com> wrote:
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.

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
