Re: [Boost-users] serialization: loading std::mapreplacesexistingmapdata objects

12 Jan 2006


      Try putting it in either the namespace of std::map (ie std) or 
in the
namespace boost::serialization

Which version of boost are you using?  I believe this may have come
up and been addressed in 1_33_1?
Now that spirit is fixed I have tried again on the CVS (1_34).
Unfortunately I now have a different error -- it prefers the serialize
template over my serialize function?
#include <map>
#include <fstream>
#include 
#include  // For std::pair
struct Mark {};
enum MarkId {low,median,high};
typedef std::map MarkMap;
void serialize(boost::archive::xml_wiarchive & ar, MarkMap & m,
const unsigned int version) {
   MarkMap::iterator it;
   for (it = m.begin() ; it != m.end(); ++it) {
       ar & boost::serialization::make_nvp("item", *it);
   }
}
int main(int argc, char* argv[])
{
  std::wifstream ifs;
  boost::archive::xml_wiarchive ar(ifs);
  MarkMap marks;
  ar & boost::serialization::make_nvp("marks",marks);
}
