Interface Summary

Interface	Description
IndexerFunction<K,V>	A strategy that distinguishes and identifies elements in an IndexedSet and IndexedMap.
IndexerFunction.IdentityKey<K,V>	A specialized IndexerFunction that distinguishes and identifies elements using identity comparison of object keys.
IndexerFunction.IntKey<V>	An IndexerFunction that distinguishes and identifies elements using int keys.
IndexerFunction.LongKey<V>	An IndexerFunction that distinguishes and identifies elements using long keys.
IntComparator	A comparison function, which imposes a total ordering on some collection of ints.
LongCollection	This class extends Collection with methods that are specific for long values.
LongComparator	A comparison function, which imposes a total ordering on some collection of longs.
LongIterator	Deprecated Use PrimitiveIterator.OfLong instead.
LongMap<V>	This class extends Map with methods that are specific for long values.
LongMap.Entry<V>	A map entry (key-value pair).
LongSet	This class extends Set with methods that are specific for long values.

Class Summary

Class	Description
AbstractConcurrentSet<E>	Provides a skeletal implementation of the Set interface to minimize the effort required to implement this interface.
AbstractLongMap<V>	This class provides a skeletal implementation of the LongMap interface, to minimize the effort required to implement this interface.

DayRange	DayRange represents a certain number of days from starting day (inclusive) to ending day (exclusive).
DayUtil	A collection of static utility methods for manipulation of int day id, that is the number of days since Unix epoch of January 1, 1970.
ExecutorProvider	Manages access to a single automatically-created Executor from a multiple references.
IdentityIndexer<K,V>	Deprecated Use IndexerFunction.IdentityKey
IndexedMap<K,V>	A wrapper around IndexedSet which implements Map interface.
IndexedSet<K,V>	A collection that contains no duplicate elements according to specified identification strategy.
IndexedSetStats	Provides access to statistics of the IndexedSet static structure.
Indexer<K,V>	Deprecated Use a functional interface IndexerFunction instead.
IndexerFunction.DefaultIdentityKey	Default identity strategy that treats values as their own keys (key == value).
IndexerFunction.DefaultIndexerFunction	Default strategy that treats values as their own keys (key == value).
LockFreePool<E>	A collection designed for pooling elements so that they can be reused later.
LoggedThreadPoolExecutor	A ScheduledThreadPoolExecutor that additionally logs uncaught exceptions and creates threads named with a given name prefix.
LogUtil
LongHashMap<V>	Hashtable based implementation of the LongMap interface.
LongHashSet	This class implements the LongSet interface, backed by a hash table (actually a LongHashMap instance).
MathUtil	A collection of non-trivial mathematical utility methods.
NumberKeyIndexer<V>	Deprecated Use functional interfaced IndexerFunction.LongKey or IndexerFunction.IntKey instead.
QuickSort	This class implements modified version of Quick Sort algorithm.
StringCache	Caches strings and provides lookup methods by raw character data to avoid string construction.
SynchronizedIndexedSet<K,V>	A synchronized thread-safe version of IndexedSet class.
SystemProperties	Utility methods for retrieving system properties without getting a SecurityException.
ThreadLocalPool<E>	Encapsulates a small thread-local pool of objects and a global LockFreePool.
TimeFormat	Utility class for parsing and formatting dates and times in ISO-compatible format.
TimePeriod	Value class for period of time with support for ISO8601 duration format.
TimeUtil	A collection of static utility methods for manipulation of Java long time.
TypedKey<T>	A typed key for TypedMap.
TypedMap	Typed thread-safe key-value map where different values have different types and are distinguished by globally-unique keys that are instances of TypedKey.
UnsafeHolder	Holds the reference to sun.misc.Unsafe instance.
WideDecimal	The WideDecimal class contains a set of methods to work with floating-point numbers packed into long primitive type.
