Examples of org.geotools.validation.spatial.LineNoSelfOverlappingValidation

org.geotools.validation.spatial.LineNoSelfOverlappingValidation
Ensure the defaultGeometry does not overlap (only works for LineString).
Tests to see if a LineString overlaps itself. It does this by breaking up the LineString into two point segments then intersects them all. If a segment has both of its points on another segment, then they overlap. This is not true in all cases and this method has to be rewritten. If a segment spans two segments, this method will say that they do not overlap when clearly they do.
