Hi again, I have now tried to get your suggested solution to work, but did not succeed.
template<typename Archive> void serialize(Archive &ar, const unsigned int) { auto * data_ptr = &data; ar & data_ptr; // load and save through pointer
if(Archive::is_loading::value) { data = std::move(*data_ptr); // no-throw ar.reset_object_address(&data, data_ptr); delete data_ptr; // not sure here }
This produced a compiler error, so I slitted it into separated load and save methods which looks like this: BOOST_SERIALIZATION_SPLIT_MEMBER(); template<class Archive> void save(Archive & ar, const unsigned int version) const { const std::vector<unsigned> * data_ptr = &data; ar & data_ptr; // load and save through pointer } template<class Archive> void load(Archive & ar, const unsigned int version) { const vector<int> * data_ptr; ar & data_ptr; // load and save through pointer data = std::move(*data_ptr); // no-throw ar.reset_object_address(&data, data_ptr); delete data_ptr; } But unfortunately, when I loads all the remaining pointers to data, the pointers has not been reset. This make me think the "ar.reset_object_address(&data, data_ptr);" method does not work properly ( I have ensured that it is executed before the loads ). Also, if I add: BOOST_STATIC_ASSERT( (boost::serialization::tracking_level< const std::vector<unsigned> * >::value != boost::serialization::track_never) ); I get an compiler error saying static assert failed. Why is that? shouldn't everything serialized through a pointer be tracked? What can I do to fix this? Best regards Allan W. Nielsen
