Class OptXYNode

java.lang.Object
  org.geotools.graph.structure.opt.OptGraphable
      org.geotools.graph.structure.opt.OptNode
          org.geotools.graph.structure.line.OptXYNode

All Implemented Interfaces:

Graphable, Node, java.io.Serializable, XYNode

public class OptXYNode

extends OptNode

implements XYNode

Optimized implementation of XYNode extended from OptNode. Instead of storing an underlying coordinate object, only a set of (x,y) values are stored eliminating the storage of additional oordinate dimensions.
