map
Maps the members of aGeometry
(which may be atomic or composite) into another Geometry of most specific type. null results are skipped. In the case of hierarchicalGeometryCollection
s, only the first level of members are mapped.- Parameters:
geom
- the input atomic or composite geometryop
- the mapping operation- Returns:
- a result collection or geometry of most specific type
-
map

flatMap
Maps the atomic elements of aGeometry
(which may be atomic or composite) using aGeometryMapper.MapOp
mapping operation into an atomic Geometry or a flat collection of the most specific type. null and empty values returned from the mapping operation are discarded.- Parameters:
geom
- the geometry to mapemptyDim
- the dimension of empty geometry to createop
- the mapping operation- Returns:
- the mapped result
