CGAL 4.7 - 2D and 3D Linear Geometry Kernel

Definition

Refines:: AdaptableFunctor (with two arguments)

See Also: CGAL::compare_xy()

Operations
A model of this concept must provide:
bool	operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q)
	returns true iff the $x$ -coordinate of `p` is smaller than the $x$ -coordinate of `q` or if the are the same and the $y$ -coordinate of `p` is smaller than the $y$ -coordinate of `q`.
