Noder () | |
Base class for Noders which make a single pass to find intersections.
This allows using a custom SegmentIntersector (which for instance may simply identify intersections, rather than insert them).

Sets the SegmentIntersector to use with this noder.
A SegmentIntersector will normally add intersection nodes to the input segment strings, but it may not - it may simply record the presence of intersections. However, some Noders may require that intersections be added.
