Lucene.Net.Spatial.Prefix.Tree.SpatialPrefixTreeFactory Class Reference

Abstract Factory for creating SpatialPrefixTree instances with useful defaults and passed on configurations defined in a Map. More...

Inherited by Lucene.Net.Spatial.Prefix.Tree.GeohashPrefixTree.Factory, and Lucene.Net.Spatial.Prefix.Tree.QuadPrefixTree.Factory.

Static Public Member Functions
static SpatialPrefixTree	MakeSPT (Dictionary< String, String > args, SpatialContext ctx)
	The factory is looked up via "prefixTree" in args, expecting "geohash" or "quad". If its neither of these, then "geohash" is chosen for a geo context, otherwise "quad" is chosen.
