Is there any way to identify objects that have changed (e.g. are to be added, updated or deleted) when you are saving an object?

If I had a parent object which had a number of child objects, would I be able to tell which child objects had been changed when the parent object is saved?

Is this possible to do before the save and/or after and which would be most sensible to use?

should contain the Interface Interceptor's which contain
[list=]findDirty
postFlush
preFlush [/list]
which you may need.
