EventExecutorGroup (Netty API Reference (4.1.22.Final))

All Superinterfaces:

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

All Known Subinterfaces:

EventExecutor ， EventLoop ， EventLoopGroup ， OrderedEventExecutor

所有已知实现类：

AbstractEventExecutor ， AbstractEventExecutorGroup ， AbstractEventLoop ， AbstractEventLoopGroup ， AbstractScheduledEventExecutor ， DefaultEventExecutor ， DefaultEventExecutorGroup ， DefaultEventLoop ， DefaultEventLoopGroup ， EpollEventLoopGroup ， GlobalEventExecutor ， ImmediateEventExecutor ， KQueueEventLoopGroup ， LocalEventLoopGroup ， MultithreadEventExecutorGroup ， MultithreadEventLoopGroup ， NioEventLoop ， NioEventLoopGroup ， NonStickyEventExecutorGroup ， OioEventLoopGroup ， SingleThreadEventExecutor ， SingleThreadEventLoop ， ThreadPerChannelEventLoop ， ThreadPerChannelEventLoopGroup ， UnorderedThreadPoolEventExecutor
```
public interface EventExecutorGroup
extends java.util.concurrent.ScheduledExecutorService, java.lang.Iterable<EventExecutor>
```
EventExecutorGroup负责通过其next()方法提供EventExecutor的使用方法。除此之外，它还负责处理它们的生命周期并允许以全球方式关闭它们。

方法摘要

所有方法接口方法抽象方法弃用的方法
Modifier and Type	Method and Description
`boolean`	`isShuttingDown()` 返回`true`当且仅当所有`EventExecutor`由该被管小号`EventExecutorGroup`正在shut down gracefully或者被关闭。
`java.util.Iterator<EventExecutor>`	`iterator()`
`EventExecutor`	`next()` 返回的一个`EventExecutor`由该被管小号`EventExecutorGroup` 。
`<V> ScheduledFuture<V>`	`schedule(java.util.concurrent.Callable<V> callable, long delay, java.util.concurrent.TimeUnit unit)`
`ScheduledFuture<?>`	`schedule(java.lang.Runnable command, long delay, java.util.concurrent.TimeUnit unit)`
`ScheduledFuture<?>`	`scheduleAtFixedRate(java.lang.Runnable command, long initialDelay, long period, java.util.concurrent.TimeUnit unit)`
`ScheduledFuture<?>`	`scheduleWithFixedDelay(java.lang.Runnable command, long initialDelay, long delay, java.util.concurrent.TimeUnit unit)`
`void`	`shutdown()` 已过时。改为`shutdownGracefully(long, long, TimeUnit)`或`shutdownGracefully()` 。
`Future<?>`	`shutdownGracefully()` 具有合理默认值的 `shutdownGracefully(long, long, TimeUnit)`的快捷方法。
`Future<?>`	`shutdownGracefully(long quietPeriod, long timeout, java.util.concurrent.TimeUnit unit)` 该执行者表示该调用者希望执行者被关闭。
`java.util.List<java.lang.Runnable>`	`shutdownNow()` 已过时。改为`shutdownGracefully(long, long, TimeUnit)`或`shutdownGracefully()` 。
`<T> Future<T>`	`submit(java.util.concurrent.Callable<T> task)`
`Future<?>`	`submit(java.lang.Runnable task)`
`<T> Future<T>`	`submit(java.lang.Runnable task, T result)`
`Future<?>`	`terminationFuture()` 返回`Future` ，当此`EventExecutorGroup`管理的所有`EventExecutor`均已终止时，通知`Future` 。

- 方法详细信息
  - isShuttingDown
```
boolean isShuttingDown()
```
    返回true当且仅当所有EventExecutor由该被管小号EventExecutorGroup正在shut down gracefully或者被关闭。
  - shutdownGracefully
```
Future<?> shutdownGracefully()
```
    具有合理默认值的 shutdownGracefully(long, long, TimeUnit)的快捷方法。
    
    结果
    
    terminationFuture()
  - shutdownGracefully
```
Future<?> shutdownGracefully(long quietPeriod,
                             long timeout,
                             java.util.concurrent.TimeUnit unit)
```
    该执行者表示该调用者希望执行者被关闭。一旦调用此方法， isShuttingDown()开始返回true ，执行程序准备关闭。与shutdown()不同，正常关机确保在关闭之前没有任何任务被提交到“安静期” （通常是几秒钟）。如果任务在安静期提交，则保证被接受，安静期将重新开始。
    
    参数
    
    quietPeriod - 文档中描述的安静期
    
    timeout - 无论任务是否在安静期间提交，等待执行程序为 shutdown()的最长时间
    
    unit - quietPeriod和 timeout的单位
    
    结果
    
    terminationFuture()
  - terminationFuture
```
Future<?> terminationFuture()
```
    返回Future ，当此EventExecutorGroup管理的所有EventExecutor都已终止时，会通知该Future 。

```
