Law_BSpFunc Class Reference

Law Function based on a BSpline curve 1d. Package
methods and classes are implemented in package Law
to construct the basis curve with several
constraints.

Public Member Functions
	Law_BSpFunc ()
	Law_BSpFunc (const Handle< Law_BSpline > &C, const Standard_Real First, const Standard_Real Last)
GeomAbs_Shape	Continuity () const
Standard_Integer	NbIntervals (const GeomAbs_Shape S) const
	Returns the number of intervals for continuity <S>. May be one if Continuity(me) >= <S>
void	Intervals (TColStd_Array1OfReal &T, const GeomAbs_Shape S) const
	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()
Standard_Real	Value (const Standard_Real X)
	Returns the value of the function at the point of parameter X.
void	D1 (const Standard_Real X, Standard_Real &F, Standard_Real &D)
	Returns the value F and the first derivative D of the function at the point of parameter X.
void	D2 (const Standard_Real X, Standard_Real &F, Standard_Real &D, Standard_Real &D2)
	Returns the value, first and seconde derivatives at parameter X.
Handle_Law_Function	Trim (const Standard_Real PFirst, const Standard_Real PLast, const Standard_Real Tol) const
	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.
void	Bounds (Standard_Real &PFirst, Standard_Real &PLast)
	Returns the parametric bounds of the function.
Handle_Law_BSpline	Curve () const
void	SetCurve (const Handle< Law_BSpline > &C)
