Class Summary

Class	Description
CachingDoubleValueSource	Caches the doubleVal of another value source in a HashMap so that it is computed only once.
DistanceToShapeValueSource	The distance from a provided Point to a Point retrieved from an ShapeValuesSource.
ReciprocalDoubleValuesSource	Transforms a DoubleValuesSource using the formula v = k / (v + k)
ShapeAreaValueSource	The area of a Shape retrieved from an ShapeValuesSource
ShapeFieldCache<T extends org.locationtech.spatial4j.shape.Shape>	Bounded Cache of Shapes associated with docIds.
ShapeFieldCacheDistanceValueSource	A DoubleValuesSource that returns the spatial distance between an input point and a document's points in ShapeFieldCacheProvider.
ShapeFieldCacheProvider<T extends org.locationtech.spatial4j.shape.Shape>	Provides access to a ShapeFieldCache for a given LeafReader.
ShapeValuesPredicate	Compares a shape from a provided ShapeValuesSource with a given Shape and sees if it matches a given SpatialOperation (the predicate).
