# Polygons

Del.» TPolygons = array of TPolygon;

C++ » typedef std::vector< Polygon > Polygons;

C# » using Polygons = List<List< IntPoint >>;

This structure is fundamental to the Clipper Library. It is used to provide polygon coordinate data to, and receive solutions from both clipping and offsetting operations.
Whether or not a contained polygon is a hole is determined by its orientation (NonZero filling rule) and its location relative to other polygons (EvenOdd filling rule).
