Interface Summary

CheckedFuture<V,X extends Exception>	A CheckedFuture is a ListenableFuture that includes versions of the get methods that can throw a checked exception.
FutureCallback<V>	A callback for accepting the results of a Future computation asynchronously.
ListenableFuture<V>	A Future that accepts completion listeners.
ListeningExecutorService	An ExecutorService that returns ListenableFuture instances.
ListeningScheduledExecutorService	A ScheduledExecutorService that returns ListenableFuture instances from its ExecutorService methods.
Service	An object with an operational state, plus asynchronous Service.start() and Service.stop() lifecycle methods to transfer into and out of this state.
TimeLimiter	Produces proxies that impose a time limit on method calls to the proxied object.
UninterruptibleFuture<V>	Deprecated. Use getUninterruptibly.

Class Summary

AbstractCheckedFuture<V,X extends Exception>	A delegating wrapper around a ListenableFuture that adds support for the AbstractCheckedFuture.checkedGet() and AbstractCheckedFuture.checkedGet(long, TimeUnit) methods.
AbstractExecutionThreadService	Base class for services that can implement AbstractExecutionThreadService.startUp(), AbstractExecutionThreadService.run() and AbstractExecutionThreadService.shutDown() methods.
AbstractFuture<V>	An abstract implementation of the ListenableFuture interface.
AbstractIdleService	Base class for services that do not need a thread while "running" but may need one during startup and shutdown.
AbstractListenableFuture<V>	Deprecated. Use AbstractFuture.
AbstractService	Base class for implementing services that can handle AbstractService.doStart() and AbstractService.doStop() requests, responding to them with AbstractService.notifyStarted() and AbstractService.notifyStopped() callbacks.
Atomics	Static utility methods pertaining to classes in the java.util.concurrent.atomic package.
Callables	Static utility methods pertaining to the Callable interface.
ExecutionList	A list of listeners, each with an associated Executor, that guarantees that every Runnable that is added will be executed after ExecutionList.execute() is called.
FakeTimeLimiter	A TimeLimiter implementation which actually does not attempt to limit time at all.
ForwardingBlockingQueue<E>	A BlockingQueue which forwards all its method calls to another BlockingQueue.
ForwardingCheckedFuture<V,X extends Exception>	A future which forwards all its method calls to another future.
ForwardingCheckedFuture.SimpleForwardingCheckedFuture<V,X extends Exception>	A simplified version of ForwardingCheckedFuture where subclasses can pass in an already constructed CheckedFuture as the delegate.
ForwardingExecutorService	An executor service which forwards all its method calls to another executor service.
ForwardingFuture<V>	A ForwardingFuture.SimpleForwardingFuture which forwards all its method calls to another future.
ForwardingFuture.SimpleForwardingFuture<V>	A simplified version of ForwardingFuture where subclasses can pass in an already constructed Future as the delegate.
ForwardingListenableFuture<V>	A ForwardingListenableFuture.SimpleForwardingListenableFuture which forwards all its method calls to another future.
ForwardingListenableFuture.SimpleForwardingListenableFuture<V>	A simplified version of ForwardingListenableFuture where subclasses can pass in an already constructed ListenableFuture as the delegate.
ForwardingListeningExecutorService	A listening executor service which forwards all its method calls to another listening executor service.
ForwardingService	A Service that forwards all method calls to another service.
Futures	Static utility methods pertaining to the Future interface.
JdkFutureAdapters	Utilities necessary for working with libraries that supply plain Future instances.
ListenableFutureTask<V>	A FutureTask that also implements the ListenableFuture interface.
Monitor	A synchronization abstraction supporting waiting on arbitrary boolean conditions.
Monitor.Guard	A boolean condition for which a thread may wait.
MoreExecutors	Factory and utility methods for Executor, ExecutorService, and ThreadFactory.
SettableFuture<V>	A ListenableFuture whose result may be set by a SettableFuture.set(Object) or SettableFuture.setException(Throwable) call.
SimpleTimeLimiter	A TimeLimiter that runs method calls in the background using an ExecutorService.
ThreadFactoryBuilder	A ThreadFactory builder, providing any combination of these features: whether threads should be marked as daemon threads a naming format a thread priority an uncaught exception handler a backing thread factory If no backing thread factory is provided, a default backing thread factory is used as if by calling setThreadFactory(Executors.defaultThreadFactory()).
UncaughtExceptionHandlers	Factories for Thread.UncaughtExceptionHandler instances.
Uninterruptibles	Utilities for treating interruptible operations as uninterruptible.
