[ZODB-Dev] Making use of the zodb transaction framework outsideof zodb?

[Petra Chong]

Many thanks to all for their replies.

Before I start reading source I tend to prefer to ask if anyone knows
directly- if no-one does, then source it is. 

Regards,

Read the Source, Luke.  ;)

I've done that a couple of times.  What you have to do, is write a data
manager class and register it with the current transaction (by calling
transaction.get().join(your_data_manager_instance)).  Then, when you get
to transaction.commit() or transaction.abort(), your data manager will
be notified accordingly.

See transaction.interfaces.IDataManager.
