NioSelectableChannelIoHandle (Netty API Reference (4.2.1.Final))

java.lang.Object
- io.netty.channel.nio.NioSelectableChannelIoHandle<S>

All Implemented Interfaces:

IoHandle, NioIoHandle, java.lang.AutoCloseable
```
public abstract class NioSelectableChannelIoHandle<S extends java.nio.channels.SelectableChannel>
extends java.lang.Object
implements IoHandle, NioIoHandle
```
Allows to create an IoHandle for a SelectableChannel, not necessarily created by Netty. This IoHandle can be used together with NioIoHandler and so have events dispatched for the SelectableChannel.
