DefaultConstructible

A model of this concept represents a multipolygon with holes. The concept requires the ability to store the polygons with holes that the multipolygon is composed of.

Has Models:

CGAL::Multipolygon_with_holes_2<Polygon>

Types
typedef unspecified_type	Polygon_with_holes_2
	the polygon type used to represent each polygon with holes of the multipolygon.
typedef unspecified_type	Polygon_const_iterator
	a bidirectional iterator over the polygons.
typedef unspecified_type	Polygons_container
	range type for iterating over holes.

Creation
template<typename InputIterator >
	MultipolygonWithHoles_2 (InputIterator begin, InputIterator end)
	constructs a multipolygon using a range of polygons.

Predicates
Size	number_of_polygons ()
	returns the number of polygons.

Access Functions
Polygon_const_iterator	polygons_begin () const
	returns the begin iterator of the polygons.
Polygon_const_iterator	polygons_end () const
	returns the past-the-end iterator of the polygons.
const Polygons_container &	polygons () const
	returns the range of polygons.

Modifiers
void	add_polygon (const Polygon_with_holes_2 &polygon)
	adds a given polygon to the multipolygon.
void	erase_polygon (Polygon_iterator pit)
	erases the specified polygon.
void	clear ()
	removes all the polygons.

Polygon_const_iterator

typedef unspecified_type MultipolygonWithHoles_2::Polygon_const_iterator
