Class SimpleNoder

java.lang.Object

org.locationtech.jts.noding.SinglePassNoder

org.locationtech.jts.noding.SimpleNoder

All Implemented Interfaces:

Noder

public class SimpleNoder
extends SinglePassNoder

Nodes a set of SegmentStrings by performing a brute-force comparison of every segment to every other one. This has n^2 performance, so is too slow for use on large numbers of segments.
