Detailed Description

Definition of the domain of parameter on a 2d-curve. Most of the time, a domain is defined by two extremities. An extremity is made of :

• a point in 2d-space (Pnt2d from gp),
• a parameter on the curve,
• a tolerance in the 2d-space. Sometimes, it can be made of 0 or 1 point ( for an infinite or semi-infinite line for example).

For Intersection algorithms, Ellipses and Circles Domains must be closed. So, SetEquivalentParameters(.,.) method must be called after initializing the first and the last bounds.

Constructor & Destructor Documentation

IntRes2d_Domain::IntRes2d_Domain

(

)

Creates an infinite Domain (HasFirstPoint = False and HasLastPoint = False).

IntRes2d_Domain::IntRes2d_Domain	(	const gp_Pnt2d &	Pnt1,
		const Standard_Real	Par1,
		const Standard_Real	Tol1,
		const gp_Pnt2d &	Pnt2,
		const Standard_Real	Par2,
		const Standard_Real	Tol2
	)

Creates a bounded Domain.

IntRes2d_Domain::IntRes2d_Domain	(	const gp_Pnt2d &	Pnt,
		const Standard_Real	Par,
		const Standard_Real	Tol,
		const Standard_Boolean	First
	)

Creates a semi-infinite Domain. If First is set to True, the given point is the first point of the domain, otherwise it is the last point.

Member Function Documentation

void IntRes2d_Domain::EquivalentParameters	(	Standard_Real &	zero,
		Standard_Real &	zeroplusperiod
	)		const

Returns Equivalent parameters if the domain is closed. Otherwise, the exception DomainError is raised.

Standard_Real IntRes2d_Domain::FirstParameter

(

)

const

Returns the parameter of the first point of the domain The exception DomainError is raised if HasFirstPoint returns False.

const gp_Pnt2d& IntRes2d_Domain::FirstPoint

(

)

const

Returns the first point of the domain. The exception DomainError is raised if HasFirstPoint returns False.

Standard_Real IntRes2d_Domain::FirstTolerance

(

)

const

Returns the tolerance of the first (left) bound. The exception DomainError is raised if HasFirstPoint returns False.

Standard_Boolean IntRes2d_Domain::HasFirstPoint

(

)

const

Returns True if the domain has a first point, i-e a point defining the lowest admitted parameter on the curve.

Standard_Boolean IntRes2d_Domain::HasLastPoint

(

)

const

Returns True if the domain has a last point, i-e a point defining the highest admitted parameter on the curve.

Standard_Boolean IntRes2d_Domain::IsClosed

(

)

const

Returns True if the domain is closed.

Standard_Real IntRes2d_Domain::LastParameter

(

)

const

Returns the parameter of the last point of the domain. The exception DomainError is raised if HasLastPoint returns False.

const gp_Pnt2d& IntRes2d_Domain::LastPoint

(

)

const

Returns the last point of the domain. The exception DomainError is raised if HasLastPoint returns False.

Standard_Real IntRes2d_Domain::LastTolerance

(

)

const

Returns the tolerance of the last (right) bound. The exception DomainError is raised if HasLastPoint returns False.

void IntRes2d_Domain::SetEquivalentParameters	(	const Standard_Real	zero,
		const Standard_Real	period
	)

Defines a closed domain.

void IntRes2d_Domain::SetValues	(	const gp_Pnt2d &	Pnt1,

		const Standard_Real	Tol1,
		const gp_Pnt2d &	Pnt2,
		const Standard_Real	Par2,
		const Standard_Real	Tol2
	)

Sets the values for a bounded domain.

void IntRes2d_Domain::SetValues

(

)
