PolygonIsValid Class Reference

#include <Concepts/PolygonIsValid.h>

Definition

Function object that determines if a sequence of points represents a valid partition polygon or not, where "valid" can assume any of several meanings (e.g., convex or \( y\)-monotone).

Has models

Creation
	PolygonIsValid (const Traits tr)
	Traits is a model of the concept required by the function that checks for validity of the polygon.

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 valid polygon.
