EpollEventLoopGroup (Netty API Reference (4.1.22.Final))

java.lang.Object
- io.netty.util.concurrent.AbstractEventExecutorGroup
- - io.netty.util.concurrent.MultithreadEventExecutorGroup
  - - io.netty.channel.MultithreadEventLoopGroup
    - - io.netty.channel.epoll.EpollEventLoopGroup

All Implemented Interfaces:

EventLoopGroup ， EventExecutorGroup ，java.lang.Iterable < EventExecutor >，java.util.concurrent.Executor，java.util.concurrent.ExecutorService中，java.util.concurrent.ScheduledExecutorService
```
public final class EpollEventLoopGroup
extends MultithreadEventLoopGroup
```
EventLoopGroup其中使用epoll的封面。正因为如此，它只能在linux上运行。

- setIoRatio
```
public void setIoRatio(int ioRatio)
```
  设置子事件循环中用于I / O所需时间的百分比。缺省值是50 ，这意味着事件循环将尝试花费I / O的时间与非I / O任务的时间相同。
- newChild
```
protected EventLoop newChild(java.util.concurrent.Executor executor,
                             java.lang.Object... args)
