java.lang.Object org.apache.lucene.facet.search.cache.CategoryListData
public class 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 CategoryListCache.register(CategoryListParams, CategoryListData)
and
CategoryListCache.loadAndRegister(CategoryListParams, IndexReader, TaxonomyReader, FacetIndexingParams)
.
