Class	Description
Accountable
ArrayUtil	Methods for manipulating arrays.
Bits	Interface for Bitset-like structures.
Bits.MatchAllBits	Bits impl of the specified length with all bits set.
Bits.MatchNoBits	Bits impl of the specified length with no bits set.
BitSet	Base implementation for a bit set.
BitUtil	A variety of high efficiency bit twiddling routines and encoders for primitives.
BytesRef	Represents byte[], as a slice (offset + length) into an existing byte[].
Constants	Some useful constants.
DocIdSetIterator
FixedBitSet	BitSet of fixed length (numBits), backed by accessible (FixedBitSet.getBits()) long[], accessed with an int index, implementing Bits.
GrowableBitSet	A BitSet implementation that grows as needed to accommodate set(index) calls.
LongHeap	A min heap that stores longs; a primitive priority queue that like all priority queues maintains a partial ordering of its elements such that the least element can always be found in constant time.
NumericUtils	Helper APIs to encode numeric values as sortable bytes and vice-versa.
PhysicalCoreExecutor	A fork join pool which is sized to match the number of physical cores on the machine (avoiding hyper-thread count) This is important for heavily vectorized sections of the code since it can easily saturate memory bandwidth.
PoolingSupport<T>	Allows any object to be pooled and released when work is done.
PoolingSupport.Pooled<T>	Wrapper class for items in the pool These are AutoClosable and are intended to be used in a try-with-resources statement.
RamUsageEstimator	Estimates the size (memory representation) of Java objects.
SparseFixedBitSet	A bit set that only stores longs that have at least one bit which is set.
