Detailed Description

The Geom2dGcc package describes qualified 2D
curves used in the construction of constrained geometric
objects by an algorithm provided by the Geom2dGcc package.
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 this solution are external to one another, or
  
• is undefined (all solutions apply).
  These package methods provide simpler functions to construct a qualified curve.
  Note: the interior of a curve is defined as the left-hand
  side of the curve in relation to its orientation.

static Geom2dGcc_QualifiedCurve Geom2dGcc::Enclosed ( const Geom2dAdaptor_Curve &  Obj )

static

 Constructs such a qualified curve that the solution <br>

computed by a construction algorithm using the qualified
curve is enclosed by the curve.
Warning
Obj 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 Obj ( mycurve )
  ;
  The qualified curve is then constructed with this object:
  Geom2dGcc_QualifiedCurve
  myQCurve = Geom2dGcc::Enclosed(Obj);
  

static Geom2dGcc_QualifiedCurve Geom2dGcc::Enclosing ( const Geom2dAdaptor_Curve &  Obj )

static

 Constructs such a qualified curve that the solution <br>

computed by a construction algorithm using the qualified
curve encloses the curve.
Warning
Obj 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 Obj ( mycurve )
  ;
  The qualified curve is then constructed with this object:
  Geom2dGcc_QualifiedCurve
  myQCurve = Geom2dGcc::Enclosing(Obj);
  

static Geom2dGcc_QualifiedCurve Geom2dGcc::Outside ( const Geom2dAdaptor_Curve &  Obj )

static

 Constructs such a qualified curve that the solution <br>

computed by a construction algorithm using the qualified
curve and the curve are external to one another.
Warning
Obj 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 Obj ( mycurve )
  ;
  The qualified curve is then constructed with this object:
  Geom2dGcc_QualifiedCurve
  myQCurve = Geom2dGcc::Outside(Obj);
  

static Geom2dGcc_QualifiedCurve Geom2dGcc::Unqualified ( const Geom2dAdaptor_Curve &  Obj )

static

 Constructs such a qualified curve that the relative <br>

position of the solution computed by a construction
algorithm using the qualified curve to the circle or line is
not qualified, i.e. all solutions apply.
Warning
Obj 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 Obj ( mycurve )
  ;
  The qualified curve is then constructed with this object:
  Geom2dGcc_QualifiedCurve
  myQCurve = Geom2dGcc::Unqualified(Obj);
