Thanks. I believe I have this OK now, but it was _much_ harder than it should have been, because the only documentation is wrong.
I tried to follow the example here: http://boost.org/libs/serialization/doc/traits.html#templates
But it looks like the correct implementation is this: namespace boost { namespace serialization {
template<class T> struct implementation_level<std::complex<T> > { // typedef mpl::int_<object_serializable> type; typedef mpl::integral_c_tag tag; typedef mpl::int_<primitive_type> type; BOOST_STATIC_CONSTANT( int, value = implementation_level::type::value ); };
// // nvp objects are generally created on the stack and are never tracked template<class T> struct tracking_level<std::complex<T> > { typedef mpl::integral_c_tag tag; typedef mpl::int_<track_never> type; BOOST_STATIC_CONSTANT( int, value = tracking_level::type::value ); BOOST_STATIC_ASSERT(( mpl::greater< /* that is a prmitive */ implementation_level< T >, mpl::int_<primitive_type> >::value )); };
} } This is what I found in level.hpp and tracking.hpp
...catching up on thread... Somehow I completely missed these flags when implementing the date-time serialization capabilities. Seems like the date-time classes should be set to primitive_types. But if I did this now, I'm going to break existing archives -- right?
