        Extract the coordinate arrays for a geometry into a List.
        Parameters:
        g - the Geometry to extract from
        coordArrayList - the List to add the coordinate arrays to
        orientPolygons - whether or not the arrays in the List should be oriented (clockwise for the shell, counterclockwise for the holes)

        desiredOrientation - CGAlgorithms.CLOCKWISE or CGAlgorithms.COUNTERCLOCKWISE
        Returns:
        a new array with entries in reverse order, if the orientation is incorrect; otherwise, the original array

      • toCoordinateArrays

        public static List toCoordinateArrays​(org.locationtech.jts.geom.Geometry g,
                                      boolean orientPolygons)
        Extract the coordinate arrays for a geometry. Polygons will be checked to ensure their rings are oriented correctly. Note: coordinates from Points or MultiPoints will not be extracted.
        Parameters:
        g - the Geometry to extract from
        orientPolygons - ensure that Polygons are correctly oriented
        Returns:
        a list of Coordinate[]
