class TQTreeObservable: public TQObservable

 TQTreeObservable

 The TQTreeObservable is a (still abstract) specialization of the abstract class TQObservable.
 It provides derived classes with an automated mechanism to access the Tree.


@observable: [TQTreeFormulaObservable] The TQTreeObservable is a still abstract class derived from
    TQObservable which is intended to be used as a base class to (usually non-abstract) Observables
    which require access to the TTree.
