[hibernate-dev] Interface for mapping classes : Programmatic API

[Sanne Grinovero]

Hi Amin,
your idea looks good to me; is this discussion affecting only
implementation or does it have some impact on APIs?
This is just to check for yourself that you're not forgetting something right?
Just wondering: it makes sense in both cases, sorry I'm looking into
it after much time.

Cheers,
Sanne
