Package com.sapportals.portal.pcd.gl.notif Description

Observer pattern that allows semantic objects to stay up-to-date.

Main purpose of these interfaces is to allow semantic objects to register to their underlying persistency object so that they can be informed of changes that were done on the persistency after the object was created. To make this mechanism secure it is important that the semantic object keeps a reference to the underlying persistency object. Only with this reference it is guaranteed that the persistency object is kept alive and the notification chain does not break.
