[Zope-dev] Hooking changes

2 Mar 2000

      Hi all,

1. Are there any method that I can override 
   to hook changes to an object?

2. And can I determine what type of change that have occurred?

3. I also what to build a change-event bubbling mechanism, that
   calls the parents change-hook until bubbling is canceled.

Here's why I'm asking: I what to build some object to which the
end-user can submit a e-mail address to be notified when a change
to that object or a sub-object has occurred.

Best Regards,
Johan Carlsson
