Class FixedBitSetFilterCache

java.lang.Object

org.elasticsearch.index.AbstractIndexComponent

org.elasticsearch.index.cache.fixedbitset.FixedBitSetFilterCache

All Implemented Interfaces:

com.google.common.cache.RemovalListener<Object,com.google.common.cache.Cache<org.apache.lucene.search.Filter,FixedBitSetFilterCache.Value>>, Closeable, AutoCloseable, org.apache.lucene.index.AtomicReader.CoreClosedListener, IndexComponent

public class FixedBitSetFilterCache
extends AbstractIndexComponent
implements org.apache.lucene.index.AtomicReader.CoreClosedListener, com.google.common.cache.RemovalListener<Object,com.google.common.cache.Cache<org.apache.lucene.search.Filter,FixedBitSetFilterCache.Value>>, Closeable

This is a cache for FixedBitSet based filters and is unbounded by size or time.

Use this cache with care, only components that require that a filter is to be materialized as a FixedBitSet and require that it should always be around should use this cache, otherwise the FilterCache should be used instead.
