Modifier and Type	Method	Description
Iterator<EventExecutor>	iterator()
void	lazyExecute(Runnable task)	Like Executor.execute(Runnable) but does not guarantee the task will be run until either a non-lazy task is executed or the executor is shut down.
protected final <T> RunnableFuture<T>	newTaskFor(Runnable runnable, T value)
protected final <T> RunnableFuture<T>	newTaskFor(Callable<T> callable)
protected static void	runTask(Runnable task)
protected static void	safeExecute(Runnable task)	Try to execute the given Runnable and just log if it throws a Throwable.
ScheduledFuture<?>	schedule(Runnable command, long delay, TimeUnit unit)
<V> ScheduledFuture<V>	schedule(Callable<V> callable, long delay, TimeUnit unit)
ScheduledFuture<?>	scheduleAtFixedRate(Runnable command, long initialDelay, long period, TimeUnit unit)
ScheduledFuture<?>	scheduleWithFixedDelay(Runnable command, long initialDelay, long delay, TimeUnit unit)
abstract void	shutdown()	Deprecated. EventExecutorGroup.shutdownGracefully(long, long, TimeUnit) or AbstractEventExecutor.shutdownGracefully() instead.
Future<?>	shutdownGracefully()	Shortcut method for EventExecutorGroup.shutdownGracefully(long, long, TimeUnit) with sensible default values.
List<Runnable>	shutdownNow()	Deprecated. EventExecutorGroup.shutdownGracefully(long, long, TimeUnit) or AbstractEventExecutor.shutdownGracefully() instead.
Future<?>	submit(Runnable task)
<T> Future<T>	submit(Runnable task, T result)

Methods inherited from interface EventExecutor

inEventLoop, inEventLoop, isExecutorThread, isSuspended, newFailedFuture, newProgressivePromise, newPromise, newSucceededFuture, trySuspend

Modifier and Type	Method	Description
default boolean	inEventLoop()	Calls EventExecutor.inEventLoop(Thread) with Thread.currentThread() as argument
boolean	inEventLoop(Thread thread)	Return true if the given Thread is executed in the event loop, false otherwise.
default boolean	isExecutorThread(Thread thread)	Return true if the given Thread is used by this ThreadAwareExecutor to execute work.
default boolean	isSuspended()	Returns true if the EventExecutor is considered suspended.
default <V> Future<V>	newFailedFuture(Throwable cause)	Create a new Future which is marked as failed already.
default <V> ProgressivePromise<V>	newProgressivePromise()	Create a new ProgressivePromise.
default <V> Promise<V>	newPromise()	Return a new Promise.
default <V> Future<V>	newSucceededFuture(V result)	Create a new Future which is marked as succeeded already.
default boolean	trySuspend()	Try to suspend this EventExecutor and return true if suspension was successful.

Methods inherited from interface EventExecutorGroup

isShuttingDown, shutdownGracefully, terminationFuture, ticker

Modifier and Type	Method	Description
boolean	isShuttingDown()	Returns true if and only if all EventExecutors managed by this EventExecutorGroup are being shut down gracefully or was shut down.
Future<?>	shutdownGracefully(long quietPeriod, long timeout, TimeUnit unit)	Signals this executor that the caller wants the executor to be shut down.
Future<?>	terminationFuture()	Returns the Future which is notified when all EventExecutors managed by this EventExecutorGroup have been terminated.
default Ticker	ticker()	The ticker for this executor.

Modifier and Type	Method	Description
ChannelFuture	register(Channel channel)	Register a Channel with this EventLoop.
