Using this:
/**
* Returns the value of the notifier's feature after the change
occurred.
* For a list-based feature, this represents a value, or a list of
values, added to the list.
* @return the new value of the notifier's feature.
*/
Object getNewValue();
It will be useful to look at how EContentAdapter processes notifications
since that covers all the cases.

Car has a containment reference to the "Wheel" model object.

When adding a Wheel to the Car, I get a notification and calling

getFeature() on the Notifier, returns the EReference object. How do
