org.geotools.validation.spatial.LineNoSelfIntersectValidation

LineNoSelfIntersectFeatureValidation purpose.

Tests to see if a geometry crosses itself. It does not detect if a segment of a LineString doubles back on itself for one segment, then terminates. A different validation is needed to test overlapping. Uses JTS' crosses routine.

Example Use:

 LineNoSelfIntersectFeatureValidation x = new LineNoSelfIntersectFeatureValidation("noSelfIntersectRoads", "Tests to see if a  geometry intersects itself", new String[] {"road"});
