Prefix Tree Strategy.

Class Summary

Class	Description
AbstractPrefixTreeQuery	Base class for Lucene Queries on SpatialPrefixTree fields.
AbstractVisitingPrefixTreeQuery	Traverses a SpatialPrefixTree indexed field, using the template and visitor design patterns for subclasses to guide the traversal and collect matching documents.
AbstractVisitingPrefixTreeQuery.VNode	A visitor node/cell found via the query shape for AbstractVisitingPrefixTreeQuery.VisitorTemplate.
BytesRefIteratorTokenStream	A TokenStream used internally by PrefixTreeStrategy.
CellToBytesRefIterator	A reset'able BytesRefIterator wrapper around an Iterator of Cells.
ContainsPrefixTreeQuery	Finds docs where its indexed shape CONTAINS the query shape.
HeatmapFacetCounter	Computes spatial facets in two dimensions as a grid of numbers.
HeatmapFacetCounter.Heatmap	Response structure
IntersectsPrefixTreeQuery	A Query matching documents that have an SpatialRelation.INTERSECTS (i.e.
NumberRangePrefixTreeStrategy	A PrefixTree based on Number/Date ranges.
NumberRangePrefixTreeStrategy.Facets	Facet response information
NumberRangePrefixTreeStrategy.Facets.FacetParentVal	Holds a block of detailLevel counts aggregated to their parent level.
PointPrefixTreeFieldCacheProvider	Implementation of ShapeFieldCacheProvider designed for PrefixTreeStrategys that index points (AND ONLY POINTS!).
PrefixTreeFacetCounter	Computes facets on cells for PrefixTreeStrategy.
PrefixTreeFacetCounter.FacetVisitor	A callback/visitor of facet counts.
PrefixTreeStrategy	An abstract SpatialStrategy based on SpatialPrefixTree.
RecursivePrefixTreeStrategy	A PrefixTreeStrategy which uses AbstractVisitingPrefixTreeQuery.
TermQueryPrefixTreeStrategy	A basic implementation of PrefixTreeStrategy using a large TermInSetQuery of all the cells from SpatialPrefixTree.getTreeCellIterator(org.locationtech.spatial4j.shape.Shape, int).
WithinPrefixTreeQuery	Finds docs where its indexed shape is WITHIN the query shape.
