EpollServerSocketChannel (Netty API Reference (4.1.22.Final))

java.lang.Object
- io.netty.util.DefaultAttributeMap
- - io.netty.channel.AbstractChannel
  - - io.netty.channel.epoll.AbstractEpollServerChannel
    - - io.netty.channel.epoll.EpollServerSocketChannel

All Implemented Interfaces:

Channel ， ChannelOutboundInvoker ， ServerChannel ， ServerSocketChannel ， UnixChannel ， AttributeMap ，java.lang.Comparable的< Channel >
```
public final class EpollServerSocketChannel
extends AbstractEpollServerChannel
implements ServerSocketChannel
```
ServerSocketChannel使用linux EPOLL Edge-Triggered Mode实现最高性能。
