Noder
public class MCIndexNoder extends SinglePassNoder
Nodes a set ofSegmentString
s using a index based onMonotoneChain
s and aSpatialIndex
. TheSpatialIndex
used should be something that supports envelope (range) queries efficiently (such as aQuadtree
} orSTRtree
(which is the default index provided).- Version:
