I found the following code in the SDO utility class; it is not really
the best location for this sort of thing...
/** Used to test for Counter Clockwise or Clockwise Linear Rings */
private static RobustCGAlgorithms clock = new RobustCGAlgorithms();
public static CoordinateSequence counterClockWise(
CoordinateSequenceFactory factory, CoordinateSequence ring) {
if (clock.isCCW(ring.toCoordinateArray())) {
return ring;
}
return Coordinates.reverse(factory, ring);
}
