Public Member Functions | |
virtual GeomAbs_Shape | Continuity () const =0 |
virtual Standard_Integer | NbIntervals (const GeomAbs_Shape S) const =0 |
Returns the number of intervals for continuity <S>. May be one if Continuity(me) >= <S> | |
virtual void | Intervals (TColStd_Array1OfReal &T, const GeomAbs_Shape S) const =0 |
Stores in <T> the parameters bounding the intervals of continuity <S>. The array must provide enough room to accomodate for the parameters. i.e. T.Length() > NbIntervals() | |
virtual Standard_Real | Value (const Standard_Real X)=0 |
Returns the value of the function at the point of parameter X. | |
virtual void | D1 (const Standard_Real X, Standard_Real &F, Standard_Real &D)=0 |
Returns the value F and the first derivative D of the function at the point of parameter X. | |
virtual void | D2 (const Standard_Real X, Standard_Real &F, Standard_Real &D, Standard_Real &D2)=0 |
Returns the value, first and seconde derivatives at parameter X. | |
virtual Handle_Law_Function | Trim (const Standard_Real PFirst, const Standard_Real PLast, const Standard_Real Tol) const =0 |
Returns a law equivalent of <me> between parameters <First> and <Last>. <Tol> is used to test for 3d points confusion. It is usfule to determines the derivatives in these values <First> and <Last> if the Law is not Cn. | |
virtual void | Bounds (Standard_Real &PFirst, Standard_Real &PLast)=0 |
Returns the parametric bounds of the function. |
