Syntax

public class SegmentStringDissolver

Remarks

A custom SegmentStringDissolver.ISegmentStringMerger merging strategy can be supplied. This strategy will be called when two identical (up to orientation) strings are dissolved together. The default merging strategy is simply to discard one of the merged strings.

A common use for this class is to merge noded edges while preserving topological labelling. This requires a custom merging strategy to be supplied to merge the topology labels appropriately.

Constructors

Creates a dissolver with the default merging strategy.
