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

[Amin Mohammed-Coleman]

Hi Sanne

Thanks for your reply. I was thinking mostly around implementation  
side of things. I guess it would be great to get an idea or discuss  
how this may impact the API. I know Emmanuel mentioned moving  
SearchMapping into an interface.

Cheers
