Field Detail

detailLevel

public final int detailLevel

The bottom-most detail-level counted, as requested.

topLeaves

public int topLeaves

The count of documents with ranges that completely spanned the parents of the detail level. In more technical terms, this is the count of leaf cells 2 up and higher from the bottom. Usually you only care about counts at detailLevel, and so you will add this number to all other counts below, including to omitted/implied children counts of 0. If there are no indexed ranges (just instances, i.e. fully specified dates) then this value will always be 0.

parents

public final SortedMap<NumberRangePrefixTree.UnitNRShape,NumberRangePrefixTreeStrategy.Facets.FacetParentVal> parents

Holds all the NumberRangePrefixTreeStrategy.Facets.FacetParentVal instances in order of the key. This is sparse; there won't be an instance if it's count and children are all 0. The keys are NumberRangePrefixTree.UnitNRShape shapes, which can be converted back to the original Object (i.e. a Calendar) via NumberRangePrefixTree.toObject(org.apache.lucene.spatial.prefix.tree.NumberRangePrefixTree.UnitNRShape).
