Sub Packages:

org.apache.lucene.util.cache    

Interfaces:

Attribute   Base interface for attributes.  code | html

Abstract Classes:

AttributeImpl   Base class for Attributes that can be added to a org.apache.lucene.util.AttributeSource code | html
AttributeSource.AttributeFactory   An AttributeFactory creates instances of AttributeImpl s.  code | html
MemoryModel   Returns primitive memory sizes for estimating RAM usage.  code | html
NumericUtils.IntRangeBuilder   Expert: Callback for #splitIntRange code | html
NumericUtils.LongRangeBuilder   Expert: Callback for #splitLongRange code | html
Parameter   A serializable Enum class.  code | html
PriorityQueue   A PriorityQueue maintains a partial ordering of its elements such that the least element can always be found in constant time.  code | html
SorterTemplate   Borrowed from Cglib.  code | html

Classes:

Version   Use by certain classes to match version compatibility across releases of Lucene.  code | html
ArrayUtil   Methods for manipulating arrays.  code | html
AttributeSource   An AttributeSource contains a list of different AttributeImpl s, and methods to add and get them.  code | html

AttributeSource.State   This class holds the state of an AttributeSource.  code | html
AverageGuessMemoryModel   An average, best guess, MemoryModel that should work okay on most systems.  code | html
BitUtil   A variety of high efficiency bit twiddling routines.  code | html
BitVector   Optimized implementation of a vector of bits.  code | html
CloseableThreadLocal   Java's builtin ThreadLocal has a serious flaw: it can take an arbitrarily long amount of time to dereference the things you had stored in it, even once the ThreadLocal instance itself is no longer referenced.  code | html
Constants   Some useful constants.  code | html
DocIdBitSet   Simple DocIdSet and DocIdSetIterator backed by a BitSet  code | html
DocIdBitSet.DocIdBitSetIterator     code | html
DummyConcurrentLock   A dummy lock as a replacement for ReentrantLock to disable locking  code | html

FieldCacheSanityChecker   Provides methods for sanity checking that entries in the FieldCache are not wasteful or inconsistent.  code | html
FieldCacheSanityChecker.Insanity   Simple container for a collection of related CacheEntry objects that in conjunction with each other represent some "insane" usage of the FieldCache.  code | html
FieldCacheSanityChecker.InsanityType   An Enumeration of the different types of "insane" behavior that may be detected in a FieldCache.  code | html
FieldCacheSanityChecker.ReaderField   Simple pair object for using "readerKey + fieldName" a Map key  code | html
IndexableBinaryStringTools   Provides support for converting byte sequences to Strings and back again.  code | html
IndexableBinaryStringTools.CodingCase     code | html
MapOfSets   Helper class for keeping Lists of Objects associated with keys. WARNING: THIS CLASS IS NOT THREAD SAFE  code | html
NamedThreadFactory   A default ThreadFactory implementation that accepts the name prefix of the created threads as a constructor argument.  code | html
NumericUtils   This is a helper class to generate prefix-encoded representations for numerical values and supplies converters to represent float/double values as sortable integers/longs.  code | html

OpenBitSetDISI   Licensed to the Apache Software Foundation (ASF) under one or more contributor license agreements.  code | html
OpenBitSetIterator   An iterator to iterate over set bits in an OpenBitSet.  code | html
RamUsageEstimator   Estimates the size of a given Object using a given MemoryModel for primitive size information.  code | html
ReaderUtil   Common util methods for dealing with IndexReader s.  code | html

ScorerDocQueue.HeapedScorerDoc     code | html
SimpleStringInterner   Simple lockless and memory barrier free String intern cache that is guaranteed to return the same String instance as String.intern() does.  code | html
SimpleStringInterner.Entry     code | html
SmallFloat   Floating point numbers smaller than 32 bits.  code | html
SortedVIntList   Stores and iterate on sorted integers in compressed form in RAM.  code | html
