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

See also: CGAL::approx_convex_partition_2(); CGAL::convex_partition_is_valid_2(); CGAL::greene_approx_convex_partition_2(); CGAL::optimal_convex_partition_2(); CGAL::partition_is_valid_2(); CGAL::y_monotone_partition_2(); CGAL::y_monotone_partition_is_valid_2()

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.
