- [section:concept_multi_polygon MultiPolygon Concept]
- [heading Description]
- [concept MultiPolygon..multi polygon]
- [heading Concept Definition]
- The MultiPolygon Concept is defined as following:
- * There must be a specialization of the metafunction `traits::tag`, defining `multi_polygon_tag` as type
- * It must behave like a Boost.Range Random Access Range
- * The type defined by the metafunction `range_value<...>::type` must fulfill
- the [link geometry.reference.concepts.concept_polygon Polygon Concept]
-
- [heading Rules]
- Besides the Concepts, which are checks on compile-time, there are
- rules that valid MultiPolygons must fulfill. See the
- [link geometry.reference.concepts.concept_polygon Polygon Concept] for more information
- on the rules a polygon (and also a multi polygon) must fulfill.
- Additionally:
- * Individual polygons making up a multi-polygon may not intersect each other,
- but tangencies are allowed.
- * One polygon might be located within the interior ring of another polygon.
