IntRes2d_Domain Class Reference

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 :

DEFINE_STANDARD_ALLOC	IntRes2d_Domain ()
	Creates an infinite Domain (HasFirstPoint = False and HasLastPoint = False).
	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 (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.
void	SetValues (const gp_Pnt2d &Pnt1, const Standard_Real Par1, const Standard_Real Tol1, const gp_Pnt2d &Pnt2, const Standard_Real Par2, const Standard_Real Tol2)
	Sets the values for a bounded domain.
void	SetValues ()
	Sets the values for an infinite domain.
void	SetValues (const gp_Pnt2d &Pnt, const Standard_Real Par, const Standard_Real Tol, const Standard_Boolean First)
	Sets the values for a semi-infinite domain.
void	SetEquivalentParameters (const Standard_Real zero, const Standard_Real period)
	Defines a closed domain.
Standard_Boolean	HasFirstPoint () const
	Returns True if the domain has a first point, i-e a point defining the lowest admitted parameter on the curve.
Standard_Real	FirstParameter () const
	Returns the parameter of the first point of the domain The exception DomainError is raised if HasFirstPoint returns False.
const gp_Pnt2d &	FirstPoint () const
	Returns the first point of the domain. The exception DomainError is raised if HasFirstPoint returns False.
Standard_Real	FirstTolerance () const
	Returns the tolerance of the first (left) bound. The exception DomainError is raised if HasFirstPoint returns False.
Standard_Boolean	HasLastPoint () const
	Returns True if the domain has a last point, i-e a point defining the highest admitted parameter on the curve.
Standard_Real	LastParameter () const
	Returns the parameter of the last point of the domain. The exception DomainError is raised if HasLastPoint returns False.
const gp_Pnt2d &	LastPoint () const
	Returns the last point of the domain. The exception DomainError is raised if HasLastPoint returns False.
Standard_Real	LastTolerance () const
	Returns the tolerance of the last (right) bound. The exception DomainError is raised if HasLastPoint returns False.
Standard_Boolean	IsClosed () const
	Returns True if the domain is closed.
void	EquivalentParameters (Standard_Real &zero, Standard_Real &zeroplusperiod) const
	Returns Equivalent parameters if the domain is closed. Otherwise, the exception DomainError is raised.

Detailed Description

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

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