Direct Known Subclasses:

DataPoint, ManagedObject, Measurement, RemoteTree, Tree

extends Object

A basic implementation of isObservable. Although this class implements all the methods of IsObservable, it does not explicitly implement the IsObservable interface. This is so that ManagedObject can extend AIDAObservable, although not all ManagedObjects implement IsObservable.
