CGAL 5.5 - 2D and 3D Linear Geometry Kernel
Kernel::OrientedSide_2 Concept Reference

## Definition

Refines:
AdaptableFunctor (with two arguments)
CGAL::Circle_2<Kernel>
CGAL::Line_2<Kernel>
CGAL::Triangle_2<Kernel>

## 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. More...

## ◆ 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.
