[Opensource] How can i create Listener Objects for DBObject?

[Gaspar Gonzalez Oliva]

Hi Mike,

Thanks for your answer but i need to explain more what i need to
do and i want that u give me some advice in what is the best way
to do.

I need to implement an object that must Listening what happened
with any DBObject, for example:

Suppose that i need to Listening ForumMail DBObject and i have
already an instance of it. How can you implement a object that
listening for any add/update/delete on this DBObject?. I need
to do this because when a DBObject made this operation i need
to do something more in other object.

If u know any code where i can take a look,
please specify me where.

Thanks in advance,

Gaspar
