All Implemented Interfaces:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler

public class AsityServerCodec
extends io.netty.channel.ChannelInboundHandlerAdapter

ChannelHandler to process HttpRequest and HttpResponse into NettyServerHttpExchange and NettyServerWebSocket. When you configure handler, you must add HttpServerCodec in front of this handler.

 ChannelPipeline pipeline = ch.pipeline();
 pipeline.addLast(new HttpServerCodec())
 .addLast(new AsityServerCodec() {
      @Override
     protected boolean accept(HttpRequest req) {
         return URI.create(req.getUri()).getPath().equals("/cettia");
     }
 }
 .onhttp(http -> {}).onwebsocket(ws -> {}));
