  - ### Method Detail

    - #### 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`
      Overrides:
        `init` in class `Channelizer.AbstractChannelizer`

    - #### supportsKeepAlive

          public boolean supportsKeepAlive()

      Keep-alive is supported through the ping/pong websocket protocol.
      See Also:
        IETF RFC 6455

    - #### createKeepAliveMessage

          public Object createKeepAliveMessage()

      Description copied from interface: `Channelizer`
      Create a message for the driver to use as a "keep-alive" for the connection. This method will only be used if `Channelizer.supportsKeepAlive()` is `true`.

    - #### close

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

      Sends a `CloseWebSocketFrame` to the server for the specified channel.
      Specified by:
        `close` in interface `Channelizer`
      Overrides:
        `close` in class `Channelizer.AbstractChannelizer`

    - #### supportsSsl

          public boolean supportsSsl()

      Overrides:
        `supportsSsl` in class `Channelizer.AbstractChannelizer`

    - #### configure

          public void configure(io.netty.channel.ChannelPipeline pipeline)

      Specified by:
        `configure` in class `Channelizer.AbstractChannelizer`

    - #### connected

          public void connected()

      Description copied from interface: `Channelizer`
      Called after the channel connects. The `Channelizer` may need to perform some functions, such as a handshake.
