[Boost-users] Serialization of static member variables?

Hi,

If see from the serialization documentation that if I serialize a
pointer more than once, only one instance will appear in the archive.

However, what about static member variables?
Will they only be serialized once, even if I serialize multiple
objects of the class type?

e.g.

class foo {
private:
   int i;
   static int j;

   friend class boost::serialization::access;
   template<class Archive> void serialize(Archive& ar, const unsigned
int version) {
      ar & i;
      ar & j;    // Will j be serialized multiple times, i.e. once per
foo instance?
   }
};

Thanks,

   Joseph
