Hi,
I'm trying to move from a custom in-house ORM to NHibernate, but have
hit one small snag. We currently have something like this (this is a
very simplified example):
public class User{
public class Lifecycle : DefaultLifecycle<User> {
public override void OnAfterSave(User u)
{ MailService.SendWelcomeMail(u); }
}
}
The way the current system works is that it analyses the model graph
and works out the change set, validates the objects, runs the before
lifecycle events, saves the objects, then runs the after lifecycle
events.
I've been experimenting with shoe-horning this feature into nhibernate
by using a custom IInterceptor, but that only gets me so far.
So what I'm thinking is wrapping up access to the ISession and running
the events myself, but to do that I need to be able to be able to work
out what is about to be flushed, and because these lifecycle events
can modify the object graph I also need to be able to work out if the
objects to be flushed has changed, and if so what has changed.
Is this possible?
