Operations
A model of this concept must provide:
Oriented_side	operator() (const Kernel::Circle_2 &c, const Kernel::Point_2 &p)
	returns CGAL::ON_ORIENTED_BOUNDARY, CGAL::ON_NEGATIVE_SIDE, or the constant CGAL::ON_POSITIVE_SIDE, depending on the position of p relative to the oriented circle c.
Oriented_side	operator() (const Kernel::Line_2 &l, const Kernel::Point_2 &p)
	returns CGAL::ON_ORIENTED_BOUNDARY, CGAL::ON_NEGATIVE_SIDE, or the constant CGAL::ON_POSITIVE_SIDE, depending on the position of p relative to the oriented line l.
Oriented_side	operator() (const Kernel::Triangle_2 &t, const Kernel::Point_2 &p)
	returns CGAL::ON_ORIENTED_BOUNDARY, CGAL::ON_NEGATIVE_SIDE, or the constant CGAL::ON_POSITIVE_SIDE, depending on the position of p relative to the oriented triangle t.
Oriented_side	operator() (const Kernel::Segment_2 &s, const Kernel::Triangle_2 &t)
	returns CGAL::ON_ORIENTED_BOUNDARY, CGAL::ON_NEGATIVE_SIDE, or the constant CGAL::ON_POSITIVE_SIDE, depending on the position of the circumcenter of t relative to the oriented supporting line of s.

operator()()

Oriented_side Kernel::OrientedSide_2::operator()	(	const Kernel::Segment_2 &	s,
		const Kernel::Triangle_2 &	t
	)

returns CGAL::ON_ORIENTED_BOUNDARY, CGAL::ON_NEGATIVE_SIDE, or the constant CGAL::ON_POSITIVE_SIDE, depending on the position of the circumcenter of t relative to the oriented supporting line of s.

The orientation of the supporting line is the same as the orientation of s.
