JDO: Events ?

[Rama Raghavan]

While were are at it, thought I'd ask..
Are there a pre/post events that consumers can register for, and be notified, when the state of an object changes and is persisted ?
Is there any event model for JDO ?

Yes, JDO has 4 events:
jdoPostLoad()
jdoPreClear()
jdoPreDelete()
jdoPreStore()
These are methods defined on an interface called InstanceCallbacks. If you want to execute some code when these events occur, you must declare your class implements InstanceCallbacks. These methods are called when the event occurs.

Now that is a nice Interface.
