public interface ChannelFutureListener
extends java.util.EventListener
```
Listens to the result of a ChannelFuture. The result of the asynchronous Channel I/O operation is notified once this listener is added by calling ChannelFuture.addListener(ChannelFutureListener).
Return the control to the caller quickly
operationComplete(ChannelFuture) is directly called by an I/O thread. Therefore, performing a time consuming task or a blocking operation in the handler method can cause an unexpected pause during I/O. If you need to perform a blocking operation on I/O completion, try to execute the operation in a different thread using a thread pool.
