方法详细信息
- 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。
- rebuildSelectors
```
public void rebuildSelectors()
```
  用新创建的 Selector替换子事件循环的当前 Selector ，以解决臭名昭着的100％CPU bug。
- newChild
```
protected EventLoop newChild(java.util.concurrent.Executor executor,
                             java.lang.Object... args)
                      throws java.lang.Exception
```
  从类复制的描述： MultithreadEventExecutorGroup
  
  创建一个新的EventExecutor，然后通过MultithreadEventExecutorGroup.next()方法访问。这个方法将被调用每个线程，将为此服务MultithreadEventExecutorGroup 。
