Package io.netty.util.concurrent

Utility classes for concurrent / async tasks.

Interface Summary

Interface	Description
AbstractEventExecutor.LazyRunnable	Deprecated. override SingleThreadEventExecutor.wakesUpForTask(java.lang.Runnable) to re-create this behaviour
EventExecutor	The EventExecutor is a special EventExecutorGroup which comes with some handy methods to see if a Thread is executed in a event loop.
EventExecutorChooserFactory	Factory that creates new EventExecutorChooserFactory.EventExecutorChoosers.
EventExecutorChooserFactory.EventExecutorChooser	Chooses the next EventExecutor to use.
EventExecutorGroup	The EventExecutorGroup is responsible for providing the 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<?>>
OrderedEventExecutor	Marker interface for EventExecutors that will process all submitted tasks in an ordered / serial fashion.
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.
RejectedExecutionHandler	Similar to RejectedExecutionHandler but specific to SingleThreadEventExecutor.
ScheduledFuture<V>	The result of a scheduled asynchronous operation.
SingleThreadEventExecutor.NonWakeupRunnable	Deprecated. override SingleThreadEventExecutor.wakesUpForTask(java.lang.Runnable) to re-create this behaviour
ThreadAwareExecutor	Executor that is aware its execution thread.
ThreadProperties	Expose details for a Thread.

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.
AbstractScheduledEventExecutor	Abstract base class for EventExecutors that want to support scheduling.
CompleteFuture<V>	A skeletal Future implementation which represents a Future which has been completed already.
DefaultEventExecutor	Default SingleThreadEventExecutor implementation which just execute all submitted task in a serial fashion.
DefaultEventExecutorChooserFactory	Default implementation which uses simple round-robin to choose next EventExecutor.
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 performance when accessed from a FastThreadLocalThread.
FastThreadLocalThread	A special Thread that provides fast access to FastThreadLocal variables.
GlobalEventExecutor	Single-thread singleton EventExecutor.
ImmediateEventExecutor	Executes Runnable objects in the caller's 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.
NonStickyEventExecutorGroup	EventExecutorGroup which will preserve Runnable execution order but makes no guarantees about what EventExecutor (and therefore Thread) will be used to execute the Runnables.
PromiseAggregator<V,F extends Future<V>>	Deprecated. Use PromiseCombiner(EventExecutor).
PromiseCombiner	A promise combiner monitors the outcome of a number of discrete futures, then notifies a final, aggregate promise when all of the combined futures are finished.
PromiseNotifier<V,F extends Future<V>>	GenericFutureListener implementation which takes other Promises and notifies them on completion.
RejectedExecutionHandlers	Expose helper methods which create different RejectedExecutionHandlers.
SingleThreadEventExecutor	Abstract base class for OrderedEventExecutor's that execute all its submitted tasks in a single thread.
SucceededFuture<V>	The CompleteFuture which is succeeded already.
ThreadPerTaskExecutor
UnaryPromiseNotifier<T>	Deprecated. use PromiseNotifier.cascade(boolean, Future, Promise).
UnorderedThreadPoolEventExecutor	Deprecated. The behavior of this event executor deviates from the typical Netty execution model and can cause subtle issues as a result.

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.
