接口 EventExecutorGroup

所有超级接口:

java.util.concurrent.Executor, java.util.concurrent.ExecutorService, java.lang.Iterable<EventExecutor>, java.util.concurrent.ScheduledExecutorService

所有已知子接口:

EventExecutor, EventLoop, EventLoopGroup, OrderedEventExecutor

所有已知实现类:

AbstractEventExecutor, AbstractEventExecutorGroup, AbstractScheduledEventExecutor, DefaultEventExecutorGroup, EpollEventLoopGroup, GlobalEventExecutor, ImmediateEventExecutor, LocalEventLoopGroup, MultithreadEventExecutorGroup, MultithreadEventLoopGroup, NioEventLoop, NioEventLoopGroup, OioEventLoopGroup, SingleThreadEventExecutor, SingleThreadEventLoop, ThreadPerChannelEventLoop, ThreadPerChannelEventLoopGroup, UnorderedThreadPoolEventExecutor

public interface EventExecutorGroup
extends java.util.concurrent.ScheduledExecutorService, java.lang.Iterable<EventExecutor>

The EventExecutorGroup is responsible for providing the EventExecutor's to use via its next() method. Besides this, it is also responsible for handling their life-cycle and allows shutting them down in a global fashion.

方法详细资料

isShuttingDown

boolean isShuttingDown()

Returns true if and only if this executor was started to be shut down gracefuclly or was shut down.

shutdownGracefully

Future<?> shutdownGracefully()

Shortcut method for shutdownGracefully(long, long, TimeUnit) with sensible default values.

返回:

the terminationFuture()

shutdownGracefully

Future<?> shutdownGracefully(long quietPeriod,
                           long timeout,
                           java.util.concurrent.TimeUnit unit)

Signals this executor that the caller wants the executor to be shut down. Once this method is called, isShuttingDown() starts to return true, and the executor prepares to shut itself down. Unlike 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.

参数:

quietPeriod - the quiet period as described in the documentation

timeout - the maximum amount of time to wait until the executor is shutdown() regardless if a task was submitted during the quiet period

unit - the unit of quietPeriod and timeout

返回:

the terminationFuture()

terminationFuture

Future<?> terminationFuture()

Returns the Future which is notified when this executor has been terminated.
