#include <CGAL/polygon_function_objects.h>

Definition

Function object class for testing if a sequence of points represents a convex polygon or not.

See Also: CGAL::convex_partition_is_valid_2(); CGAL::Partition_is_valid_traits_2<Traits, PolygonIsValid>

Implementation

This test requires $O(n)$ time for a polygon with $n$ vertices.

Creation
	Is_convex_2 (const Traits &t)
	`Traits` satisfies the requirements of the function `is_convex_2()`

Operations
template<class InputIterator >
bool	operator() (InputIterator first, InputIterator beyond)
	returns `true` iff the points of type `Traits::Point_2` in the range [`first`,`beyond`) define a convex polygon.
