Hi Nikhil, osg::Observer is a class to derive from if you want to receive a notification when any other (Referenced) object, previously added/assigned to the Observer, gets deleted.
For instance the osg::observer_ptr is a kind of smart pointer that is automatically set himself to NULL when the object he's pointing to is deleted. For another example of usage, see class "QuicktimeInitializer" in the quicktime plugin.
