Class Summary

Class	Description
ArrayUtils
BigArrays	Utility class to work with arrays.
BloomFilter	A bloom filter.
BloomFilter.Factory	A factory that can use different fpp based on size.
BloomFilter.Factory.Entry
BytesRefHash	Specialized hash table implementation similar to Lucene's BytesRefHash that maps BytesRef values to ids.
CancellableThreads	A utility class for multi threaded operation that needs to be cancellable via interrupts.
ExtensionPoint	This class defines an official elasticsearch extension point.
ExtensionPoint.ClassMap<T>	A map based extension point which allows to register keyed implementations ie.
ExtensionPoint.ClassSet<T>	A set based extension point which allows to register extended classes that might be used to chain additional functionality etc.
ExtensionPoint.InstanceMap<K,V>	A an instance of a map, mapping one instance value to another.
ExtensionPoint.SelectedType<T>	A Type extension point which basically allows to registerd keyed extensions like ExtensionPoint.ClassMap but doesn't instantiate and bind all the registered key value pairs but instead replace a singleton based on a given setting via ExtensionPoint.SelectedType.bindType(Binder, Settings, String, String) Note: ExtensionPoint.bind(Binder) is not supported by this class
LocaleUtils	Utilities for for dealing with Locale objects
LongHash	Specialized hash table implementation similar to BytesRefHash that maps long values to ids.
LongObjectPagedHashMap<T>	A hash table from native longs to objects.
LongObjectPagedHashMap.Cursor<T>
MinimalMap<K,V>
MultiDataPathUpgrader
SingleObjectCache<T>	A very simple single object cache that allows non-blocking refresh calls triggered by expiry time.
URIPattern	URI Pattern matcher The pattern is URI in which authority, path, query and fragment can be replace with simple pattern.
