java.lang.Objectcom.vividsolutions.jts.noding.FastNodingValidator
public class FastNodingValidator
Validates that a collection of SegmentString
s is correctly noded.
Indexing is used to improve performance.
In the most common use case, validation stops after a single
non-noded intersection is detected.
Does NOT check a-b-a collapse situations.
Also does not check for endpoint-interior vertex intersections.
This should not be a problem, since the noders should be
able to compute intersections between vertices correctly.
The client may either test the isValid
condition,
or request that a suitable TopologyException
be thrown.
