Method Detail

transformCoordinates

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

snapLine

private Coordinate[] snapLine(Coordinate[] srcPts,
                              Coordinate[] snapPts)
