Operations
A model of this concept must provide:
bool	operator() (const Kernel::Direction_2 &d, const Kernel::Direction_2 &d1, const Kernel::Direction_2 &d2)
	returns true iff d is not equal to d1, and while rotating counterclockwise starting at d1, d is reached strictly before d2 is reached.

Member Function Documentation

operator()()

bool Kernel::CounterclockwiseInBetween_2::operator()	(	const Kernel::Direction_2 &	d,
		const Kernel::Direction_2 &	d1,
		const Kernel::Direction_2 &	d2
	)

returns true iff d is not equal to d1, and while rotating counterclockwise starting at d1, d is reached strictly before d2 is reached.

Note that true is returned if d1 == d2, unless also d == d1.
