### Uses of PrefixTreeStrategy in org.apache.lucene.spatial.prefix

Subclasses of PrefixTreeStrategy in org.apache.lucene.spatial.prefix
`class` `NumberRangePrefixTreeStrategy` A PrefixTree based on Number/Date ranges.
`class` `RecursivePrefixTreeStrategy` A `PrefixTreeStrategy` which uses `AbstractVisitingPrefixTreeQuery`.

Methods in org.apache.lucene.spatial.prefix with parameters of type PrefixTreeStrategy
`static HeatmapFacetCounter.Heatmap` HeatmapFacetCounter.`calcFacets(PrefixTreeStrategy strategy, IndexReaderContext context, Bits topAcceptDocs, org.locationtech.spatial4j.shape.Shape inputShape, int facetLevel, int maxCells)` Calculates spatial 2D facets (aggregated counts) in a grid, sometimes called a heatmap.
`static void` PrefixTreeFacetCounter.`compute(PrefixTreeStrategy strategy, IndexReaderContext context, Bits topAcceptDocs, org.locationtech.spatial4j.shape.Shape queryShape, int facetLevel, PrefixTreeFacetCounter.FacetVisitor facetVisitor)` Computes facets using a callback/visitor style design, allowing flexibility for the caller to determine what to do with each underlying count.
`static void` PrefixTreeFacetCounter.`compute(PrefixTreeStrategy strategy, LeafReaderContext context, Bits acceptDocs, org.locationtech.spatial4j.shape.Shape queryShape, int facetLevel, PrefixTreeFacetCounter.FacetVisitor facetVisitor)` Lower-level per-leaf segment method.
