All Implemented Interfaces:

ChannelHandler, ChannelInboundHandler, ChannelOutboundHandler

@ChannelHandler.Sharable
public class HelloWorldHttp2Handler
extends ChannelDuplexHandler

A simple handler that responds with the message "Hello World!".

This example is making use of the "multiplexing" http2 API, where streams are mapped to child Channels. This API is very experimental and incomplete.
