    - #### close

          public void close(io.netty.channel.Channel channel)

      Description copied from interface: `Channelizer`
      Called on `Connection.close()` to perform an `Channelizer` specific functions. Note that the `Connection` already calls `Channel.close()` so there is no need to call that method here. An implementation will typically use this method to send a `Channelizer` specific message to the server to notify of shutdown coming from the client side (e.g. a "close" websocket frame).
      Specified by:
        `close` in interface `Channelizer`

    - #### init

          public void init(org.apache.tinkerpop.gremlin.driver.Connection connection)

      Description copied from interface: `Channelizer`
      Initializes the `Channelizer`. Called just after construction.
      Specified by:
        `init` in interface `Channelizer`

    - #### initChannel

          protected void initChannel(io.netty.channel.socket.SocketChannel socketChannel)
                              throws Exception

      Specified by:
        `initChannel` in class `io.netty.channel.ChannelInitializer<io.netty.channel.socket.SocketChannel>`
      Throws:
        `Exception`
