## Detailed Description

Describes functions for building a qualified 2D curve. A qualified 2D curve is a curve with a qualifier which specifies whether the solution of a construction algorithm using the qualified curve (as an argument):

• encloses the curve, or
• is enclosed by the curve, or
• is built so that both the curve and it are external to one another, or
• is undefined (all solutions apply).

## ◆ Geom2dGcc_QualifiedCurve()

 Geom2dGcc_QualifiedCurve::Geom2dGcc_QualifiedCurve ( const Geom2dAdaptor_Curve & Curve, const GccEnt_Position Qualifier )

Constructs a qualified curve by assigning the qualifier Qualifier to the curve Curve. Qualifier may be:

• GccEnt_enclosing if the solution of a construction algorithm using the qualified curve encloses the curve, or
• GccEnt_enclosed if the solution is enclosed by the curve, or
• GccEnt_outside if both the solution and the curve are external to one another, or
• GccEnt_unqualified if all solutions apply. Note: The interior of a curve is defined as the left-hand side of the curve in relation to its orientation. Warning Curve is an adapted curve, i.e. an object which is an interface between:
• the services provided by a 2D curve from the package Geom2d,
• and those required on the curve by a computation algorithm. The adapted curve is created in the following way: Handle(Geom2d_Curve) mycurve = ... ; Geom2dAdaptor_Curve Curve ( mycurve ) ; The qualified curve is then constructed with this object: GccEnt_Position myQualif = GccEnt_outside ; Geom2dGcc_QualifiedCurve myQCurve ( Curve, myQualif ); is private;

## ◆ IsEnclosed()

 Standard_Boolean Geom2dGcc_QualifiedCurve::IsEnclosed ( ) const

It returns true if the solution is Enclosed in the Curv and false in the other cases.

## ◆ IsEnclosing()

 Standard_Boolean Geom2dGcc_QualifiedCurve::IsEnclosing ( ) const

It returns true if the solution is Enclosing the Curv and false in the other cases.

## ◆ IsOutside()

 Standard_Boolean Geom2dGcc_QualifiedCurve::IsOutside ( ) const

It returns true if the solution is Outside the Curv and false in the other cases.

## ◆ IsUnqualified()

 Standard_Boolean Geom2dGcc_QualifiedCurve::IsUnqualified ( ) const

Returns true if the solution is unqualified and false in the other cases.

## ◆ Qualified()

Returns a 2D curve to which the qualifier is assigned. Warning The returned curve is an adapted curve, i.e. an object which is an interface between:

• the services provided by a 2D curve from the package Geom2d,
• and those required on the curve by a computation algorithm. The Geom2d curve on which the adapted curve is based can be obtained in the following way: myQualifiedCurve = ... ; Geom2dAdaptor_Curve myAdaptedCurve = myQualifiedCurve.Qualified(); Handle(Geom2d_Curve) = myAdaptedCurve.Curve();

## ◆ Qualifier()

 GccEnt_Position Geom2dGcc_QualifiedCurve::Qualifier ( ) const

Returns.

• the qualifier of this qualified curve if it is enclosing, enclosed or outside, or
• GccEnt_noqualifier if it is unqualified.
