        protected CoordinateSequence transformCoordinates​(CoordinateSequence coords,
                                                          Geometry parent)
        Description copied from class: GeometryTransformer
        Transforms a CoordinateSequence. This method should always return a valid coordinate list for the desired result type. (E.g. a coordinate list for a LineString must have 0 or at least 2 points). If this is not possible, return an empty sequence - this will be pruned out.
        Overrides:
        transformCoordinates in class GeometryTransformer
        Parameters:
        coords - the coordinates to transform
        parent - the parent geometry
        Returns:
        the transformed coordinates
      • createValidArea

        private Geometry createValidArea​(Geometry roughAreaGeom)
        Creates a valid area geometry from one that possibly has bad topology (i.e. self-intersections). Since buffer can handle invalid topology, but always returns valid geometry, constructing a 0-width buffer "corrects" the topology. Note this only works for area geometries, since buffer always returns areas. This also may return empty geometries, if the input has no actual area.
        Parameters:
        roughAreaGeom - an area geometry possibly containing self-intersections
        Returns:
        a valid area geometry
