#include <Concepts/MinCircle2Traits.h>

Definition

This concept defines the requirements for traits classes of CGAL::Min_circle_2<Traits>.

Has Models:: CGAL::Min_circle_2_traits_2<K>

See also: CGAL::Min_circle_2<Traits>

Types
typedef unspecified_type	Point
	The point type must provide default and copy constructor, assignment and equality test. More...

typedef unspecified_type	Circle
	The circle type must fulfill the requirements listed below in the next section. More...

Variables
Circle	circle
	The current circle. More...

Creation
Only default and copy constructor are required.
	MinCircle2Traits ()

	MinCircle2Traits (const MinCircle2Traits &)

Operations
The following predicate is only needed, if the member function `is_valid` of `Min_circle_2` is used.
CGAL::Orientation	orientation (const Point &p, const Point &q, const Point &r) const
	returns constants `CGAL::LEFT_TURN`, `CGAL::COLLINEAR`, or `CGAL::RIGHT_TURN` iff `r` lies properly to the left of, on, or properly to the right of the oriented line through `p` and `q`, resp. More...

◆ orientation()

CGAL::Orientation MinCircle2Traits::orientation	(	const Point &	p,
		const Point &	q,
		const Point &	r
	)		const

returns constants CGAL::LEFT_TURN, CGAL::COLLINEAR, or CGAL::RIGHT_TURN iff r lies properly to the left of, on, or properly to the right of the oriented line through p and q, resp.
