public class MCIndexNoder extends SinglePassNoder
SegmentStrings using a index based
on MonotoneChains and a SpatialIndex.
The SpatialIndex used should be something that supports
envelope (range) queries efficiently (such as a Quadtree}
or HPRtree (which is the default index provided).
The noder supports using an overlap tolerance distance . This allows determining segment intersection using a buffer for uses involving snapping with a distance tolerance.
