[Boost-users] [serialization] Removing empty classes

1 Feb 2006

      Hello,

Let's say I have a structure suce as this :

class A {};
class B : public A {};
class C : public B {};

Currently, I have some code that looks like this :

template<class Archive>
void C::serialize(Archive &ar,  const unsigned int version)
{
   ar & BOOST_SERIALIZATION_BASE_OBJECT_NVP(B);
}

However, if my class B is "empty", that is it adds no data to A, is this 
possible as an optimisation to just write :

template<class Archive>
void C::serialize(Archive &ar,  const unsigned int version)
{
   ar & BOOST_SERIALIZATION_BASE_OBJECT_NVP(A);
}

Or will this break something ?
