Basic implementation of Geometry, constructed and destructed by GeometryFactory.
Definition: Geometry.h:186
Creates an areal geometry formed by the constituent linework of given geometry.
Definition: BuildArea.h:54
BuildArea()=default
Create a BuildArea object.
std::unique_ptr< geom::Geometry > build(const geom::Geometry *geom)
Return the area built fromthe constituent linework of the input geometry.
Basic namespace for all GEOS functionalities.
