- Method Detail
  - next
```
EventLoop next()
```
    Return the next EventLoop to use
    
    Specified by:
    
    next in interface EventExecutorGroup
  - register
```
ChannelFuture register(Channel channel)
```
    Register a Channel with this EventLoop. The returned ChannelFuture will get notified once the registration was complete.
  - register
```
ChannelFuture register(ChannelPromise promise)
```
    Register a Channel with this EventLoop using a ChannelFuture. The passed ChannelFuture will get notified once the registration was complete and also will get returned.
  - register
```
@Deprecated
ChannelFuture register(Channel channel,
                       ChannelPromise promise)
```
    Deprecated.
    Use register(ChannelPromise) instead.
    
    Register a Channel with this EventLoop. The passed ChannelFuture will get notified once the registration was complete and also will get returned.
