Function Object Concept PolygonIsValid

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).

Creation

PolygonIsValid f ( Traits t);
	Traits is a model of the concept required by the function that checks for validity of the polygon.

Operations

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

Has Models

CGAL::Is_convex_2<Traits>
CGAL::Is_y_monotone_2<Traits>
