  - bind
```
public ChannelFuture bind(SocketAddress localAddress)
```
    Request to bind to the given SocketAddress and notify the ChannelFuture once the operation completes, either because the operation was successful or because of an error.
    This will result in having the ChannelOperationHandler.bind(ChannelHandlerContext, SocketAddress, ChannelPromise) method called of the next ChannelOperationHandler contained in the ChannelPipeline of the Channel.
  - connect
```
public ChannelFuture connect(SocketAddress remoteAddress)
```
    Request to connect to the given SocketAddress and notify the ChannelFuture once the operation completes, either because the operation was successful or because of an error.
    If the connection fails because of a connection timeout, the ChannelFuture will get failed with a ConnectTimeoutException. If it fails because of connection refused a ConnectException will be used.
    This will result in having the ChannelOperationHandler.connect(ChannelHandlerContext, SocketAddress, SocketAddress, ChannelPromise) method called of the next ChannelOperationHandler contained in the ChannelPipeline of the Channel.
  - connect
```
public ChannelFuture connect(SocketAddress remoteAddress,
                    SocketAddress localAddress)
```
    Request to connect to the given SocketAddress while bind to the localAddress and notify the ChannelFuture once the operation completes, either because the operation was successful or because of an error.

    This will result in having the ChannelOperationHandler.close(ChannelHandlerContext, ChannelPromise) method called of the next ChannelOperationHandler contained in the ChannelPipeline of the Channel.
  - deregister
```
public ChannelFuture deregister()
```
    Request to deregister this ChannelOutboundInvoker from the previous assigned EventExecutor and notify the ChannelFuture once the operation completes, either because the operation was successful or because of an error.

    Be aware that the flush could be only partially successful. In such cases the ChannelFuture will be failed with an IncompleteFlushException. So if you are interested to know if it was partial successful you need to check if the returned Future.cause() returns an instance of IncompleteFlushException. In such cases you may want to call flush(ChannelPromise) or flush() to flush the rest of the data or just close the connection via close(ChannelPromise) or close() if it is not possible to recover.
    This will result in having the ChannelOperationHandler.flush(ChannelHandlerContext, ChannelPromise) method called of the next ChannelOperationHandler contained in the ChannelPipeline of the Channel.

In such cases the ChannelFuture will be failed with a IncompleteFlushException. In such cases you may want to call flush(ChannelPromise) or flush() to flush the rest of the data or just close the connection via close(ChannelPromise) or close() if it is not possible to recover.
    This will result in having the message added to the outbound buffer of the next ChannelOutboundHandler and the ChannelOperationHandler.flush(ChannelHandlerContext, ChannelPromise) method called of the next ChannelOperationHandler contained in the ChannelPipeline of the Channel.
