class QualifiedCirc
from GccEnt
---Purpose: Creates a qualified 2d Circle.
-- A qualified 2D circle is a circle (gp_Circ2d circle) with a
-- qualifier which specifies whether the solution of a
-- construction algorithm using the qualified circle (as an argument):
-- - encloses the circle, or
-- - is enclosed by the circle, or
-- - is built so that both the circle and it are external to one another, or
-- - is undefined (all solutions apply).

uses Position from GccEnt,
Circ2d from gp
is
Create(Qualified : Circ2d from gp ;
Qualifier : Position from GccEnt ) returns QualifiedCirc from GccEnt;
---Purpose: Constructs a qualified circle by assigning the qualifier
-- Qualifier to the circle Qualified. Qualifier may be:
-- - GccEnt_enclosing if the solution computed by a
-- construction algorithm using the qualified circle
-- encloses the circle, or
-- - GccEnt_enclosed if the solution is enclosed by the circle, or
-- - GccEnt_outside if both the solution and the circle
-- are external to one another, or
-- - GccEnt_unqualified if all solutions apply.

---Purpose: Returns a 2D circle to which the qualifier is assigned.
Qualifier(me) returns Position from GccEnt
is static;
---Purpose: Returns
-- - the qualifier of this qualified circle, if it is enclosing,
-- enclosed or outside, or
-- - GccEnt_noqualifier if it is unqualified.
IsUnqualified(me) returns Boolean from Standard
is static;
---Purpose: Returns true if the Circ2d is Unqualified and false in
-- the other cases.
IsEnclosing(me) returns Boolean from Standard
is static;
---Purpose: Returns true if the solution computed by a construction
-- algorithm using this qualified circle encloses the circle.
IsEnclosed(me) returns Boolean from Standard
is static;
---Purpose: Returns true if the solution computed by a construction
-- algorithm using this qualified circle is enclosed by the circle.
IsOutside(me) returns Boolean from Standard
is static;
---Purpose: Returns true if both the solution computed by a
-- construction algorithm using this qualified circle and the
-- circle are external to one another.
