[hibernate-dev] Integrator and retrieving objects

[Steve Ebersole]

Just to circle back to this (because my memory is so short)..

What did we ever decide about this, especially in regards to the *how*?

As and example, lets look at Search.  Search wraps Session in a 
FullTextSession.  Search would register some handler with the 
SessionFactory that says it knows how to handle Session.as( 
FullTextSession.class ) calls.  But what exactly is this handler going 
to do?  Unless Search maintains some global Session instance -> 
FullTextSession instance...  Or are you thinking the registration 
happens per-Session?
