Geometric functions split_multi_linestring
- split_multi_linestring(arc_poly_dataitem)
- split_multi_linestring (arc_poly_dataitem) results in a new uint32 domain-unit with arcs or polygons. A null coordinate in the arc_poly_dataitem argument is interpreted as separator. The resulting number of entries is the number of null coordinates in the arc_poly_dataitem plus 1.
The split_multi_linestring function generates two subitems:
- geometry: the geometry of the new polygons. This attribute has the same values unit as the arc_poly_dataitem argument.
- org_rel: a relation for the new domain towards the domain of the arc_poly_dataitem argument.
