Detailed Description

Models a collection of Polygons.

As per the OGC SFS specification, the Polygons in a MultiPolygon may not overlap, and may only touch at single points. This allows the topological point-set semantics to be well-defined.

Constructor & Destructor Documentation

◆ MultiPolygon()

geos::geom::MultiPolygon::MultiPolygon	(	std::vector< std::unique_ptr< Polygon > > &&	newPolys,
		const GeometryFactory &	newFactory
	)

protected

Construct a MultiPolygon.

Parameters

newPolys the Polygons for this MultiPolygon, or null or an empty array to create the empty geometry. Elements may be empty Polygons, but not nulls. The polygons must conform to the assertions specified in the OpenGIS Simple Features Specification for SQL .

Constructed object will take ownership of the vector and its elements.

Parameters

newFactory The GeometryFactory used to create this geometry Caller must keep the factory alive for the life-time of the constructed MultiPolygon.
