Class MCIndexNoder

java.lang.Object
  com.vividsolutions.jts.noding.SinglePassNoder
      com.vividsolutions.jts.noding.MCIndexNoder

All Implemented Interfaces:

Noder

public class MCIndexNoder
extends SinglePassNoder

Nodes a set of 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 STRtree (which is the default index provided).

getMonotoneChains

public java.util.List getMonotoneChains()

getIndex

public SpatialIndex getIndex()

getNodedSubstrings

public java.util.Collection getNodedSubstrings()

Description copied from class: SinglePassNoder

Returns a Collection of fully noded SegmentStrings. The SegmentStrings have the same context as their parent.

Specified by:

getNodedSubstrings in interface Noder

Specified by:

getNodedSubstrings in class SinglePassNoder

Returns:

a Collection of SegmentStrings

computeNodes

public void computeNodes(java.util.Collection inputSegStrings)

Description copied from class: SinglePassNoder

Computes the noding for a collection of SegmentStrings. Some Noders may add all these nodes to the input SegmentStrings; others may only add some or none at all.

Specified by:

computeNodes in interface Noder

Specified by:

computeNodes in class SinglePassNoder

Parameters:

inputSegStrings - a collection of SegmentStrings to node
