CGAL 5.6.1 - 2D and 3D Linear Geometry Kernel



A model of this concept must provide:

bool operator() (const Kernel::Point_2 &p, const Kernel::Point_2 &q)
 returns true iff the \( y\)-coordinate of p is smaller than the \( y\)-coordinate of q or if they are the same and the \( x\)-coordinate of p is smaller than the \( x\)-coordinate of q.
