| LineNoSelfOverlappingValidation | | public class LineNoSelfOverlappingValidation extends DefaultFeatureValidation (Code) | | 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.
