Re: [Boost-users] [Serialization] NVP and xml archives

15 Nov 2006


      This isn't an NVP - its a list of NVPs

Try
        list<V> sl;
    ...
        ar & BOOST_SERIALIZATION_NVP(sl);

Well I thought it should and I suspect that I am doing something silly
but this is basically the class I have:
template  class test
{
   friend class boost::serialization::access;
   list< boost::serialization::nvp<V> > sl;
   template<class Archive>
   void serialize(Archive & ar, const unsigned int version)
   {
       ar & BOOST_SERIALIZATION_NVP(sl);
}
public:
{
...
}
and it gets caught in the compile trap
template<class T>
   void save_override(T & t, BOOST_PFTO int)
   {
       // If your program fails to compile here, its most likely due
to
       // not specifying an nvp wrapper around the variable to
       // be serialized.
       BOOST_STATIC_ASSERT(0 == sizeof(T));
   }
I thought that a nvp should be serializable automatically.
Ideas?
Thanks in advance

Doesn't it already do this?

Hi All,
I have a class that contains a list of name value pairs . I would
like the serialization to use the names for the tag names in the xml
archive. Is there a way to do this or do I need to write my own
custom archive?
Thanks in advance
Michael
