      • map

        public static Geometry map​(Geometry geom,
                                   GeometryMapper.MapOp op)
        Maps the members of a Geometry (which may be atomic or composite) into another Geometry of most specific type. null results are skipped. In the case of hierarchical GeometryCollections, only the first level of members are mapped.
        Parameters:
        geom - the input atomic or composite geometry
        op - the mapping operation
        Returns:
        a result collection or geometry of most specific type
      • flatMap

        public static Geometry flatMap​(Geometry geom,
                                       int emptyDim,
                                       GeometryMapper.MapOp op)
        Maps the atomic elements of a Geometry (which may be atomic or composite) using a GeometryMapper.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 map
        emptyDim - the dimension of empty geometry to create
        op - the mapping operation
        Returns:
        the mapped result
