get timer instance from ReadTimeoutHandler subclasses

[谢非]

hi all,

    I need to start the timeout timer in channelConnected() event handler of
a ReadTimeoutHandler subclass, but it seems that there is no protected
getTimer() in ReadTimeoutHandler.
    should I store the timer as a member field like this:

      class ServerReadTimeoutHandler extends ReadTimeoutHandler {
             Timer timer;

             public ServerReadTimeoutHandler(Timer timer, int
timeoutSeconds) {
                         super(timer, timeoutSeconds);
                          this.timer = timer;
             }

            @Override
            public void channelConnected(ChannelHandlerContext ctx,
ChannelStateEvent e) throws Exception {
                 timer.start();
                 super.channelConnected(ctx, e);
            }
     }
