Class NumberRangePrefixTreeStrategy

java.lang.Object

org.apache.lucene.spatial.SpatialStrategy

org.apache.lucene.spatial.prefix.PrefixTreeStrategy

org.apache.lucene.spatial.prefix.RecursivePrefixTreeStrategy

org.apache.lucene.spatial.prefix.NumberRangePrefixTreeStrategy

public class NumberRangePrefixTreeStrategy
extends RecursivePrefixTreeStrategy

A PrefixTree based on Number/Date ranges. This isn't very "spatial" on the surface (to the user) but it's implemented using spatial so that's why it's here extending a SpatialStrategy. When using this class, you will use various utility methods on the prefix tree implementation to convert objects/strings to/from shapes. To use with dates, pass in DateRangePrefixTree.

WARNING: This API is experimental and might change in incompatible ways in the next release.
