Channelizer (Apache TinkerPop 3.5.5 API)

All Superinterfaces:

io.netty.channel.ChannelHandler

All Known Implementing Classes:

AbstractChannelizer, HttpChannelizer, UnifiedChannelizer, WebSocketChannelizer, WsAndHttpChannelizer
```
public interface Channelizer
extends io.netty.channel.ChannelHandler
```
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.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	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.
