Detailed Description

Describes an linear evolution law.

Constructor & Destructor Documentation

◆ Law_Linear()

Law_Linear::Law_Linear ( )

Constructs an empty linear evolution law.

Member Function Documentation

◆ Bounds()

void Law_Linear::Bounds	(	Standard_Real &	PFirst,
		Standard_Real &	PLast
	)

overridevirtual

Returns the parametric bounds of the function.

Implements Law_Function.

◆ Continuity()

GeomAbs_Shape Law_Linear::Continuity ( ) const

overridevirtual

Returns GeomAbs_CN.

Implements Law_Function.

◆ D1()

void Law_Linear::D1	(	const Standard_Real	X,
		Standard_Real &	F,
		Standard_Real &	D
	)

overridevirtual

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

Implements Law_Function.

◆ D2()

void Law_Linear::D2	(	const Standard_Real	X,
		Standard_Real &	F,
		Standard_Real &	D,
		Standard_Real &	D2
	)

overridevirtual

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

Implements Law_Function.

◆ Intervals()

void Law_Linear::Intervals	(	TColStd_Array1OfReal &	T,
		const GeomAbs_Shape	S
	)		const

overridevirtual

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()

Implements Law_Function.

◆ NbIntervals()

Standard_Integer Law_Linear::NbIntervals ( const GeomAbs_Shape S ) const

overridevirtual

Returns 1.

Implements Law_Function.

◆ Set()

void Law_Linear::Set	(	const Standard_Real	Pdeb,
		const Standard_Real	Valdeb,
		const Standard_Real	Pfin,
		const Standard_Real	Valfin
	)

Defines this linear evolution law by assigning both:

the bounds Pdeb and Pfin of the parameter, and
the values Valdeb and Valfin of the function at these two parametric bounds.

◆ Trim()

Handle< Law_Function > Law_Linear::Trim	(	const Standard_Real	PFirst,
		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.
