Utility classes for concurrent / async tasks.

Interface Summary

Interface	Description
EventExecutor	The EventExecutor is a special EventExecutorGroup which comes with some handy methods to see if a Thread is executed in a event loop.
EventExecutorGroup	The EventExecutorGroup is responsible to provide EventExecutor's to use via its EventExecutorGroup.next() method.
Future<V>	The result of an asynchronous operation.
FutureListener<V>	A subtype of GenericFutureListener that hides type parameter for convenience.
GenericFutureListener<F extends Future<?>>	Listens to the result of a Future.
GenericProgressiveFutureListener<F extends ProgressiveFuture<?>>
ProgressiveFuture<V>	A Future which is used to indicate the progress of an operation.
ProgressivePromise<V>	Special ProgressiveFuture which is writable.
Promise<V>	Special Future which is writable.
ScheduledFuture<V>	The result of an scheduled asynchronous operation.

Class Summary

Class	Description
AbstractEventExecutor	Abstract base class for EventExecutor implementations.
AbstractEventExecutorGroup	Abstract base class for EventExecutorGroup implementations.
AbstractFuture<V>	Abstract Future implementation which does not allow for cancellation.
CompleteFuture<V>	A skeletal Future implementation which represents a Future which has been completed already.
DefaultEventExecutorGroup	Default implementation of MultithreadEventExecutorGroup which will use DefaultEventExecutor instances to handle the tasks.
DefaultProgressivePromise<V>
DefaultPromise<V>
DefaultThreadFactory	A ThreadFactory implementation with a simple naming rule.
FailedFuture<V>	The CompleteFuture which is failed already.
FastThreadLocal<V>	A special variant of ThreadLocal that yields higher access performan when accessed from a FastThreadLocalThread.
FastThreadLocalThread	A special Thread that provides fast access to FastThreadLocal variables.
GlobalEventExecutor	Single-thread singleton EventExecutor.
ImmediateEventExecutor	AbstractEventExecutor which execute tasks in the callers thread.
ImmediateExecutor	Executor which execute tasks in the callers thread.
MultithreadEventExecutorGroup	Abstract base class for EventExecutorGroup implementations that handles their tasks with multiple threads at the same time.
SingleThreadEventExecutor	Abstract base class for EventExecutor's that execute all its submitted tasks in a single thread.
SucceededFuture<V>	The CompleteFuture which is succeeded already.

Exception Summary

Exception	Description
BlockingOperationException	An IllegalStateException which is raised when a user performed a blocking operation when the user is in an event loop thread.
