Description

Class Summary
AbstractPrefixTreeFilter: Base class for Lucene Filters on SpatialPrefixTree fields.
AbstractVisitingPrefixTreeFilter: Traverses a `SpatialPrefixTree` indexed field, using the template & visitor design patterns for subclasses to guide the traversal and collect matching documents.
AbstractVisitingPrefixTreeFilter.VNode: A Visitor Node/Cell found via the query shape for `AbstractVisitingPrefixTreeFilter.VisitorTemplate`.
IntersectsPrefixTreeFilter: A Filter matching documents that have an `SpatialRelation.INTERSECTS` (i.e.
PointPrefixTreeFieldCacheProvider: Implementation of `ShapeFieldCacheProvider` designed for `PrefixTreeStrategy`s.
PrefixTreeStrategy: An abstract SpatialStrategy based on `SpatialPrefixTree`.
RecursivePrefixTreeStrategy: A `PrefixTreeStrategy` which uses `AbstractVisitingPrefixTreeFilter`.
TermQueryPrefixTreeStrategy: A basic implementation of `PrefixTreeStrategy` using a large `TermsFilter` of all the nodes from `SpatialPrefixTree.getNodes(com.spatial4j.core.shape.Shape, int, boolean, boolean)`.
