Modifier and Type	Method	Description
boolean	awaitTermination(long timeout, TimeUnit unit)
final int	executorCount()	Return the number of EventExecutor this implementation uses.
boolean	isShutdown()
boolean	isShuttingDown()	Returns true if and only if all EventExecutors managed by this EventExecutorGroup are being shut down gracefully or was shut down.
boolean	isTerminated()
Iterator<EventExecutor>	iterator()
protected ThreadFactory	newDefaultThreadFactory()
EventExecutor	next()	Returns one of the EventExecutors managed by this EventExecutorGroup.
void	shutdown()	Deprecated.
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.
