[Zope] where changed() method defined ?

4 Oct 2003

      Greetings,

I'm making a Zope product 
imitating some sample products.

I encountered codes like "self.__changed__(1)",
notifying ZODB that this object has changed.

I wornder where the method __changed__() defined ?
I greped Zope source code under lib/python/,
but not found.
