virtual void Law_Function::Bounds | ( | Standard_Real & | PFirst,
|  | Standard_Real & | PLast
| ) |  |
| pure virtual

Returns the parametric bounds of the function.

Implemented in Law_Composite, Law_Linear, Law_BSpFunc, and Law_Constant.

virtual GeomAbs_Shape Law_Function::Continuity | ( |  | ) | const
| pure virtual

Implemented in Law_Composite, Law_Linear, Law_BSpFunc, and Law_Constant.

virtual void Law_Function::D1 | ( | const Standard_Real | X,
|  | Standard_Real & | F,
|  | Standard_Real & | D
| ) |  |
| pure virtual

Returns the value F and the first derivative D of the function at the point of parameter X.

Implemented in Law_Composite, Law_BSpFunc, Law_Linear, and Law_Constant.

virtual void Law_Function::D2 | ( | const Standard_Real | X,
|  | Standard_Real & | F,
|  | Standard_Real & | D,
|  | Standard_Real & | D2
| ) |  |
| pure virtual

Returns the value, first and seconde derivatives at parameter X.

Implemented in Law_Composite, Law_Linear, Law_BSpFunc, and Law_Constant.

virtual void Law_Function::Intervals | ( | TColStd_Array1OfReal & | T,
|  | const GeomAbs_Shape | S
| ) |  | const
| pure virtual

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()

Implemented in Law_Composite, Law_BSpFunc, Law_Linear, and Law_Constant.

virtual Standard_Integer Law_Function::NbIntervals | ( | const GeomAbs_Shape | S | ) | const
| pure virtual

Returns the number of intervals for continuity <S>. May be one if Continuity(me) >= <S>

Implemented in Law_Composite, Law_Linear, Law_BSpFunc, and Law_Constant.

virtual Handle< Law_Function > Law_Function::Trim | ( | const Standard_Real | PFirst,
|  | const Standard_Real | PLast,
|  | const Standard_Real | Tol
| ) |  | const
| pure virtual

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.

Implemented in Law_Composite, Law_Linear, Law_BSpFunc, and Law_Constant.

virtual Standard_Real Law_Function::Value | ( | const Standard_Real | X | ) |
| pure virtual

Returns the value of the function at the point of parameter X.
