java.lang.Object
  com.vividsolutions.jts.noding.SegmentStringDissolver

public class SegmentStringDissolver
extends java.lang.Object

Dissolves a noded collection of SegmentStrings to produce a set of merged linework with unique segments. A custom merging strategy can be applied when two identical (up to orientation) strings are dissolved together. The default merging strategy is simply to discard the merged string.

A common use for this class is to merge noded edges while preserving topological labelling.
