| class MContactDbObserver |
The interface for an observer that handles changes to a contact database.
It specifies a single pure virtual function which should be implemented by the observer class to test the type of the change event (see the TContactDbObserverEventType enum) and handle it.
There is no need for the observer class to explicitly test for all possible event types - the event is for information only and event types which are of no interest to the observer class can safely be ignored.
The change event type (TContactDbObserverEventType) may be augmented in future releases with additional values.
A contact database observer pointer is passed to the NewL() function for the CContactChangeNotifier class.
