Channelizer (Apache TinkerPop 3.7.0-SNAPSHOT API)

All Superinterfaces:

io.netty.channel.ChannelHandler

All Known Implementing Classes:

Channelizer.AbstractChannelizer, Channelizer.WebSocketChannelizer
```
public interface Channelizer
extends io.netty.channel.ChannelHandler
```
Client-side channel initializer interface. It is responsible for constructing the Netty ChannelPipeline used by the client to connect and send message to Gremlin Server.

- Method Detail
  - init
```
void init(org.apache.tinkerpop.gremlin.driver.Connection connection)
```
    Initializes the Channelizer. Called just after construction.
  - close
```
void close(io.netty.channel.Channel channel)
```
    Called on Connection.closeAsync() 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).
  - connected
```
default void connected()
```
    Called after the channel connects. The Channelizer may need to perform some functions, such as a handshake.
