  Method
  Description
  `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)`
