Examples of IObservable

org.eclipse.core.databinding.observable.IObservable
An object with state that allows to listen for state changes.
Implementations must not manage listeners themselves, listener management must be delegated to a private instance of type {@link ChangeSupport} if itis not inherited from {@link AbstractObservable}.
@noimplement This interface is not intended to be implemented by clients.Clients should instead subclass one of the classes in the framework that implement this interface. Note that direct implementers of this interface outside of the framework will be broken in future releases when methods are added to this interface. @since 1.0
