PolygonIsValid Concept Reference
Function Object Concepts

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.
