org.apache.lucene.facet.search.cache.CategoryListData

Category list data maintained in RAM.

Speeds up facets accumulation when more RAM is available.

Note that this will consume more memory: one int (4 bytes) for each category of each document.

Note: at the moment this class is insensitive to updates of the index, and, in particular, does not make use of Lucene's ability to refresh a single segment.

See {@link CategoryListCache#register(CategoryListParams,CategoryListData)}and {@link CategoryListCache#loadAndRegister(CategoryListParams,IndexReader,TaxonomyReader,FacetIndexingParams)}. @lucene.experimental
