Member Function Documentation

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
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.

Implemented in Law_Composite, Law_BSpFunc, Law_Linear, and Law_Constant.
