Detailed Description

The ObjSubject class represents a subject that notifies observers about object operations and actions.

This class provides functionality for subscribing and unsubscribing observers to receive notifications about the creation and deletion of object instances initiated by the server, as well as required restore actions for objects.

The ObjSubject class is designed to be inherited by other classes that require observer functionality.

Note

The ObjSubject class requires the presence of ObjOpObserver and ObjActObserver classes for observer functionality.
