Detailed Description

An implementation of the Lucene ValueSource model to support spatial relevance ranking.

Constructor & Destructor Documentation

Lucene.Net.Spatial.Util.ShapeFieldCacheDistanceValueSource.ShapeFieldCacheDistanceValueSource	(	SpatialContext	ctx,
		ShapeFieldCacheProvider< Point >	provider,
		Point	from
	)

override string Lucene.Net.Spatial.Util.ShapeFieldCacheDistanceValueSource.Description ( )

virtual

description of field, used in explain()

override bool Lucene.Net.Spatial.Util.ShapeFieldCacheDistanceValueSource.Equals ( object o )

override int Lucene.Net.Spatial.Util.ShapeFieldCacheDistanceValueSource.GetHashCode ( )

virtual

Needed for possible caching of query results - used by ValueSourceQuery.GetHashCode().

override DocValues Lucene.Net.Spatial.Util.ShapeFieldCacheDistanceValueSource.GetValues ( IndexReader reader )

virtual

Return the DocValues used by the function query.

Parameters

reader the IndexReader used to read these values. If any caching is involved, that caching would also be IndexReader based.

<throws> IOException for any error. </throws>
