Returns the parametric bounds of the function.

Implements Law_Function.

◆ Continuity()

GeomAbs_Shape Law_BSpFunc::Continuity ( ) const
overridevirtual

Implements Law_Function.

◆ Curve()

Handle< Law_BSpline > Law_BSpFunc::Curve ( ) const

◆ D1()

void Law_BSpFunc::D1 ( const Standard_Real  X,
Standard_Real F,
Standard_Real D 
)
overridevirtual

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

Implements Law_Function.

void Law_BSpFunc::D2 ( const Standard_Real  X,
Standard_Real F,
Standard_Real D,
Standard_Real D2

const Standard_Real  PLast,
const Standard_Real  Tol 
) const
overridevirtual

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.

Implements Law_Function.

◆ Value()

Standard_Real Law_BSpFunc::Value ( const Standard_Real  X)
overridevirtual

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

Implements Law_Function.
