Re: [Boost-users] [serialization] Serializing derived template classvia base pointer

Daniel Mitchell wrote:

Hi everyone, has any progress has been made on a general solution for this problem? Given classes like these,

struct base { template<typename Archive> void serialize(Archive& ar, unsigned version) { } virtual ~base() = default; };

template<typename T> struct derived : base { template<typename Archive> void serialize(Archive& ar, unsigned version) { ar & data; } T data; };

is it possible to serialize the derived type (with T unknown) via a base pointer? Sticking a call to register_type<derived> in derived::serialize doesn't seem to do it.

There are several demos in the examples directory which show how to do this. Robert Ramey
