|
| GeneralPolygonWithHoles_2::General_polygon_2 | |
|
the general-polygon type used to
represent the outer boundary and each hole. Must Model the GeneralPolygon_2 Concept.
| |
| GeneralPolygonWithHoles_2::Hole_const_iterator | |
|
a bidirectional iterator
over the polygonal holes. Its value type is
General_polygon_2.
| |
| GeneralPolygonWithHoles_2 polygon; | |
|
default constructor.
| |
| GeneralPolygonWithHoles_2 polygon ( other); | |
|
copy constructor.
| |
| GeneralPolygonWithHoles_2 | polygon = other | assignment operator. |
| GeneralPolygonWithHoles_2 polygon ( General_polygon_2 & outer); | |
|
constructs a general polygon with holes that has no holes using a given general polygon outer as the outer boundary.
| |
| template <class InputIterator> | |
| GeneralPolygonWithHoles_2 polygon ( General_polygon_2 & outer, InputIterator begin, InputIterator end); | |
|
constructs a general polygon with holes using a given general polygon
outer as the outer boundary and a given range of holes. If outer
is an empty general polygon, then an unbounded polygon with holes will be
created. The holes must be contained inside the outer boundary, and the
polygons representing the holes must be simple and pairwise disjoint, except
perhaps at the vertices.
| |
| bool | polygon.is_unbounded () | returns true if the outer boundary is empty, and false otherwise. |
| General_polygon_2 | polygon.outer_boundary () const | returns the general polygon that represents the outer boundary. Note that this polygon is not necessarily a valid (simple) general polygon because it may be relatively simple. |
| Hole_const_iterator | polygon.holes_begin () const | returns the begin iterator of the holes. |
| Hole_const_iterator | polygon.holes_end () const | returns the past-the-end iterator of the holes. |
