uses	
     Label            from TDF,

     Trsf             from gp

    Create returns mutable TransformationDriver from DNaming;
    ---Purpose: Constructor

    ---Purpose: validation
    --          ==========

    Validate(me; theLog : in out Logbook from TFunction)
    is redefined;
    ---Purpose: Validates labels of a function in <log>.
    --          In regeneration mode this method must be called (by the
    --          solver) even if the function is not executed, to build
    --          the valid label scope.

    ---Purpose: execution of function
    --          ======================

    MustExecute (me; theLog : Logbook from TFunction)
    ---Purpose: Analyse in <log> if the loaded function must be executed
    --          (i.e.arguments are modified) or not.
    --          If the Function label itself is modified, the function must
    --          be executed.
    returns Boolean from Standard
    is redefined;

    Execute (me; theLog : in out Logbook from TFunction)
    ---Purpose: Execute the function and push in <log> the impacted
    --          labels (see method SetImpacted).
    returns Integer from Standard
    is redefined;
