CGAL::Is_convex_2<Traits>

Definition

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

#include <CGAL/polygon_function_objects.h>

Is Model for the Concept

PolygonIsValid

Creation

Is_convex_2<Traits> f ( Traits t);
	Traits satisfies the requriements of the function is_convex_2

Operations

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

Implementation

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