 CGAL 5.0 - 2D and 3D Linear Geometry Kernel
Kernel::HasOnNegativeSide_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:

bool operator() (const Kernel::Circle_2 &c, const Kernel::Point_2 &p)
returns true iff p lies on the negative side of c.

bool operator() (const Kernel::Line_2 &l, const Kernel::Point_2 &p)
returns true iff p lies on the negative side of l (l is considered a half-space).

bool operator() (const Kernel::Triangle_2 &t, const Kernel::Point_2 &p)
returns true iff p lies on the negative side of t.
