Notifications on creation of EObjects [message #653521]

Hi,

Is there a way to get notifications on creation of EObjects just like the way we can get for modifying its feature like add, remove, move and so on..

Thanks and regards,
Priya

Notifications are only sent for actual modification of existing objects, not for object creation. How would you attach an adapter to an object before you can get hold of it?

You are notified, though, when you attach your new object to the contents of an existing object.

Was just wondering then what exactly is the type Notification.CREATE meant for?

Thanks,
Priya

Basically I am creating an EObject this way (copying/duplicating)

EObject create(EObject eObject) {
return eObject.eClass().getEpackage().getEFactoryInstance().create( eObject.eClass());
}

when this happens I want to set some relation between the original EObject and the newly created EObject. I want to handle this in a notification handler way. Please let me know if there is a way to do this?

Thanks,
Priya

I see it's obsolete:

@Deprecated
int CREATE = 0;

I guess has never been used, just like EStore.create(EClass)...
