Operations
A model of this concept must provide:
Kernel::Point_2	operator() (const Kernel::Segment_2 &s, int i)
	returns source or target of s: fo(s,0) returns the source of s, fo(s,1) returns the target of s. More...
Kernel::Point_2	operator() (const Kernel::Iso_rectangle_2 &r, int i)
	returns the i'th vertex of r in counterclockwise order, starting with the lower left vertex. More...
Kernel::Point_2	operator() (const Kernel::Triangle_2 &t, int i)
	returns the i'th vertex of t. More...

Member Function Documentation

operator()() [1/3]

Kernel::Point_2 Kernel::ConstructVertex_2::operator()	(	const Kernel::Segment_2 &	s,
		int	i
	)

returns source or target of s: fo(s,0) returns the source of s, fo(s,1) returns the target of s.

The parameter i is taken modulo 2.

operator()() [2/3]

Kernel::Point_2 Kernel::ConstructVertex_2::operator()	(	const Kernel::Iso_rectangle_2 &	r,
		int	i
	)

returns the i'th vertex of r in counterclockwise order, starting with the lower left vertex.

The parameter i is taken modulo 4.

operator()() [3/3]

Kernel::Point_2 Kernel::ConstructVertex_2::operator()	(	const Kernel::Triangle_2 &	t,
		int	i
	)

returns the i'th vertex of t.

The parameter i is taken modulo 3.
