  • Method Details

    • 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
    • map

      public static Collection map(Collection geoms, GeometryMapper.MapOp op)
    • 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
