Detailed Description

class cuspatial::multipolygon_range< GeometryIterator, PartIterator, RingIterator, VecIterator >
class cuspatial::multipolygon_range< GeometryIterator, PartIterator, RingIterator, VecIterator >
Non-owning range-based interface to multipolygon data.
Provides a range-based interface to contiguous storage of multipolygon data, to make it easier to access and iterate over multipolygons, polygons, rings and points.
Conforms to GeoArrow's specification of multipolygon: https://github.com/geopandas/geo-arrow-spec/blob/main/format.md
- Template Parameters
-
GeometryIterator iterator type for the geometry offset array. Must meet the requirements of LegacyRandomAccessIterator. PartIterator iterator type for the part offset array. Must meet the requirements of LegacyRandomAccessIterator. RingIterator iterator type for the ring offset array. Must meet the requirements of LegacyRandomAccessIterator. VecIterator iterator type for the point array. Must meet the requirements of LegacyRandomAccessIterator.
- Note
- Though this object is host/device compatible, The underlying iterator must be device accessible if used in device kernel.
