Class Summary

Class	Description
AbstractRefCounted	A basic RefCounted implementation that is initialized with a ref count of 1 and calls AbstractRefCounted.closeInternal() once it reaches a 0 ref count
AbstractRunnable	An extension to runnable.
AtomicArray<E>	A list backed by an AtomicReferenceArray with potential null values, easily allowing to get the concrete values as a list using AtomicArray.asList().
AtomicArray.Entry<E>	An entry within the array.
BaseFuture<V>	An abstract implementation of the ListenableFuture interface.
ConcurrentCollections
ConcurrentHashMapLong<T>
CountDown	A simple thread safe count-down class that in contrast to a CountDownLatch never blocks.
EsAbortPolicy
EsExecutors
EsThreadPoolExecutor	An extension to thread pool executor, allowing (in the future) to add specific additional stats to it.
FutureUtils
KeyedLock<T>	This class manages locks.
LoggingRunnable
PrioritizedCallable<T>
PrioritizedEsThreadPoolExecutor	A prioritizing executor which uses a priority queue as a work queue.
PrioritizedEsThreadPoolExecutor.Pending
PrioritizedRunnable
ReleasableLock	Releasable lock used inside of Engine implementations
SizeBlockingQueue<E>	A size based queue wrapping another blocking queue to provide (somewhat relaxed) capacity checks.
ThreadBarrier	A synchronization aid that allows a set of threads to all wait for each other to reach a common barrier point.
ThreadBarrier.BarrierTimer	A Barrier action to be used in conjunction with ThreadBarrier to measure performance between barrier awaits.
