## Interface Channelizer

- All Known Implementing Classes:
    AbstractChannelizer, HttpChannelizer, NioChannelizer, WebSocketChannelizer, WsAndHttpChannelizer

      public interface Channelizer

  An interface that makes it possible to plugin different Netty pipelines to Gremlin Server, enabling the use of different protocols, mapper security and other such functions. A `Channelizer` implementation can be configured in Gremlin Server with the `channelizer` setting in the configuration file.

    All Methods Instance Methods Abstract Methods Default Methods
    Modifier and Type | Method and Description
    --- | ---
    `default Object` | `createIdleDetectionMessage()` Create a message to send to seemingly dead clients to see if they respond back.
    `void` | `init(ServerGremlinExecutor serverGremlinExecutor)` This method is called just after the `Channelizer` is initialized.
    `default boolean` | `supportsIdleMonitor()` Determines if the channelizer supports a method for keeping the connection alive and auto-closing zombie channels.

- - ### Method Detail

    - #### init

          void init(ServerGremlinExecutor serverGremlinExecutor)

      This method is called just after the `Channelizer` is initialized.

    - #### createIdleDetectionMessage

          default Object createIdleDetectionMessage()

      Create a message to send to seemingly dead clients to see if they respond back. The message sent will be dependent on the implementation. For example, a websocket implementation would create a "ping" message. This method will only be used if `supportsIdleMonitor()` is `true`.

    - #### supportsIdleMonitor

          default boolean supportsIdleMonitor()

      Determines if the channelizer supports a method for keeping the connection alive and auto-closing zombie channels.
