29 //! Creates a qualified 2d Circle.
30 //! A qualified 2D circle is a circle (gp_Circ2d circle) with a
31 //! qualifier which specifies whether the solution of a
32 //! construction algorithm using the qualified circle (as an argument):
33 //! - encloses the circle, or
34 //! - is enclosed by the circle, or
35 //! - is built so that both the circle and it are external to one another, or
36 //! - is undefined (all solutions apply).

45 //! Qualifier to the circle Qualified. Qualifier may be:

47 //! construction algorithm using the qualified circle
48 //! encloses the circle, or
49 //! - GccEnt_enclosed if the solution is enclosed by the circle, or
50 //! - GccEnt_outside if both the solution and the circle
51 //! are external to one another, or
