NHibernate - How to Iterate Persistent Entities Attached to a Session?

Question

I have a need to inspect the set of attached entities that would be persisted if I called Flush() on a given session. (I'm writing code that accesses a Session as part of a generic pipeline before saving and it can be used in any number of contexts.)

I find myself wishing that there were a method like

mySession.GetPersistentEntities()

so I could inspect them and perform some preprocessing.

Anyone know of a way to do this?

Thanks,

Jeff

No, NHibernate's ISession does not expose anything like that. You can either:

• Track these instances yourself (not recommended)
• Use standard NHibernate mechanisms:
  • Event listeners (e.g. IFlushEventListener, ISaveOrUpdateEventListener)
  • Interceptors (IInterceptor.OnFlushDirty(), OnSave())
