public final class UnorderedThreadPoolEventExecutor extends ScheduledThreadPoolExecutor implements EventExecutor
EventExecutor
implementation which makes no guarantees about the ordering of task execution that
are submitted because there may be multiple threads executing these tasks.
This implementation is most useful for protocols that do not need strict ordering.
Because it provides no ordering care should be taken when using it!ThreadPoolExecutor.AbortPolicy, ThreadPoolExecutor.CallerRunsPolicy, ThreadPoolExecutor.DiscardOldestPolicy, ThreadPoolExecutor.DiscardPolicy

public Future<?> shutdownGracefully(long quietPeriod, long timeout, TimeUnit unit)
EventExecutorGroup
EventExecutorGroup.isShuttingDown()
starts to return true
, and the executor prepares to shut itself down.
Unlike EventExecutorGroup.shutdown()
, graceful shutdown ensures that no tasks are submitted for 'the quiet period'
(usually a couple seconds) before it shuts itself down. If a task is submitted during the quiet period,
it is guaranteed to be accepted and the quiet period will start over.shutdownGracefully
in interface EventExecutorGroup
quietPeriod
- the quiet period as described in the documentationtimeout
- the maximum amount of time to wait until the executor is EventExecutorGroup.shutdown()
regardless if a task was submitted during the quiet periodunit
- the unit of quietPeriod
and timeout
