[hibernate-dev] Hibernate.getImplementation(Object)

[Max Rydahl Andersen]

afaik ( ( HibernateProxy ) value  
).getHibernateLazyInitializer().getImplementation() haven't changed almost  
since beginning of times.

But exposing it on the Hibernate class API would be wrong IMO since the  
return value would be the underlying object instead of the proxy, or
do I misunderstand what you want it to return ?
