Operations
A model of this concept must provide:
bool	operator() (const Kernel::Point_2 &p, const Kernel::Point_2 &q, const Kernel::Point_2 &r)
	returns true iff the three points p, q and r form a left turn or if they are collinear and the distance of q to p is larger than the distance of r to p, where p is the point passed to the object at construction. More...

bool Kernel::LessRotateCCW_2::operator()	(	const Kernel::Point_2 &	p,
		const Kernel::Point_2 &	q,
		const Kernel::Point_2 &	r
	)

returns true iff the three points p, q and r form a left turn or if they are collinear and the distance of q to p is larger than the distance of r to p, where p is the point passed to the object at construction.

Precondition

p does not lie in the interior of the segment rq, i.e. p is an extreme point with respect to \( \{p,q,r\}\).
