Class ClosestFeaturesHT

java.lang.Object
  vclip.ClosestFeaturesHT

public class ClosestFeaturesHT

extends java.lang.Object

Implements a hash table for use by vclip to store the most recent closest features between pairs of PolyTrees. Use of this information generally improves the performance of subsequent calls to vclip, provided that the spatial relationship between PolyTrees is not changing too rapidly.
