tracks how much total RAM is in use. |

optimized for BytesRef instances. |
BytesRefHash.BytesStartArray | Manages allocation of the per-term addresses. |
BytesRefHash.DirectBytesStartArray | A simple BytesRefHash.BytesStartArray that tracks
memory allocation using a private AtomicLong
instance. |
CharsRef | Represents char[], as a slice (offset + length) into an existing char[]. |
CloseableThreadLocal<T> | 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. |
CollectionUtil | Methods for manipulating (sorting) collections. |
CommandLineUtil | Class containing some useful methods used by command line tools |
Constants | Some useful constants. |
Counter | Simple counter class |
DocIdBitSet | Simple DocIdSet and DocIdSetIterator backed by a BitSet |
DoubleBarrelLRUCache<K extends DoubleBarrelLRUCache.CloneableKey,V> | Simple concurrent LRU cache, using a "double barrel" approach where two ConcurrentHashMaps record entries. |
DoubleBarrelLRUCache.CloneableKey | Object providing clone(); the key class must subclass this. |
FieldCacheSanityChecker | Provides methods for sanity checking that entries in the FieldCache are not wasteful or inconsistent. |
FieldCacheSanityChecker.Insanity | Simple container for a collection of related CacheEntry objects that in conjunction with each other represent some "insane" usage of the FieldCache. |
FieldCacheSanityChecker.InsanityType | An Enumeration of the different types of "insane" behavior that may be detected in a FieldCache. |
FilterIterator<T> | An Iterator implementation that filters elements with a boolean predicate. |
FixedBitSet | BitSet of fixed length (numBits), backed by accessible
(FixedBitSet.getBits() ) long[], accessed with an int index,
implementing Bits and DocIdSet. |
IndexableBinaryStringTools | Deprecated. Implement TermToBytesRefAttribute and store bytes directly
instead. |
InfoStream | Debugging API for Lucene classes such as IndexWriter
and SegmentInfos . |
IntBlockPool | A pool for int blocks similar to ByteBlockPool |
IntBlockPool.Allocator | Abstract class for allocating and freeing int blocks. |
IntBlockPool.DirectAllocator | A simple IntBlockPool.Allocator that never recycles. |
IntBlockPool.SliceReader | A IntBlockPool.SliceReader that can read int slices written by a IntBlockPool.SliceWriter |
IntBlockPool.SliceWriter | A IntBlockPool.SliceWriter that allows to write multiple integer slices into a given IntBlockPool . |
IntsRef | Represents int[], as a slice (offset + length) into an existing int[]. |
IOUtils | This class emulates the new Java 7 "Try-With-Resources" statement. |
LongsRef | Represents long[], as a slice (offset + length) into an existing long[]. |
MapOfSets<K,V> | Helper class for keeping Lists of Objects associated with keys. |
MathUtil | Math static utility methods. |
NamedSPILoader<S extends NamedSPILoader.NamedSPI> | Helper class for loading named SPIs from classpath (e.g. |
NamedThreadFactory | A default ThreadFactory implementation that accepts the name prefix
of the created threads as a constructor argument. |
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. |
NumericUtils.IntRangeBuilder | Callback for NumericUtils.splitIntRange(org.apache.lucene.util.NumericUtils.IntRangeBuilder, int, int, int) . |
NumericUtils.LongRangeBuilder | Callback for NumericUtils.splitLongRange(org.apache.lucene.util.NumericUtils.LongRangeBuilder, int, long, long) . |
OpenBitSet | An "open" BitSet implementation that allows direct access to the array of words storing the bits. |
OpenBitSetDISI | OpenBitSet with added methods to bulk-update the bits
from a DocIdSetIterator . |
OpenBitSetIterator | An iterator to iterate over set bits in an OpenBitSet. |
PagedBytes | Represents a logical byte[] as a series of pages. |
PagedBytes.Reader | Provides methods to read BytesRefs from a frozen PagedBytes. |
PrintStreamInfoStream | InfoStream implementation over a PrintStream
such as System.out . |
PriorityQueue<T> | A PriorityQueue maintains a partial ordering of its elements such that the least element can always be found in constant time. |
RamUsageEstimator | Estimates the size (memory representation) of Java objects. |
RecyclingByteBlockAllocator | A ByteBlockPool.Allocator implementation that recycles unused byte
blocks in a buffer and reuses them in subsequent calls to
RecyclingByteBlockAllocator.getByteBlock() . |
RecyclingIntBlockAllocator | A IntBlockPool.Allocator implementation that recycles unused int
blocks in a buffer and reuses them in subsequent calls to
RecyclingIntBlockAllocator.getIntBlock() . |
RollingBuffer<T extends RollingBuffer.Resettable> | Acts like forever growing T[], but internally uses a circular buffer to reuse instances of T. |
SentinelIntSet | A native int set where one value is reserved to mean "EMPTY" |
SetOnce<T> | A convenient class which offers a semi-immutable object wrapper implementation which allows one to set the value of an object exactly once, and retrieve it many times. |
SmallFloat | Floating point numbers smaller than 32 bits. |
SorterTemplate | This class was inspired by CGLIB, but provides a better QuickSort algorithm without additional InsertionSort at the end. |
SPIClassIterator<S> | Helper class for loading SPI classes from classpath (META-INF files). |
StringHelper | Methods for manipulating strings. |
ToStringUtils | Helper methods to ease implementing Object.toString() . |
UnicodeUtil | Class to encode java's UTF16 char[] into UTF8 byte[] without always allocating a new byte[] as String.getBytes("UTF-8") does. |

IdentityHashMap . |
