All Implemented Interfaces:

ChannelHandler, ChannelInboundHandler

public class VibeServerCodec
extends ChannelInboundHandlerAdapter

ChannelHandler to process HttpRequest and HttpResponse into NettyServerHttpExchange and NettyServerWebSocket. You need to configure this handler and provide your action to receive ServerHttpExchange and ServerWebSocket by overriding httpAction() and wsAction() like the following usage. When you configure handler, you must add HttpServerCodec in front of this handler.

 
 ChannelPipeline pipeline = ch.pipeline();
 pipeline.addLast(new HttpServerCodec())
 .addLast(new VibeServerCodec() {
     @Override
     protected boolean accept(HttpRequest req) {
         return URI.create(req.getUri()).getPath().equals("/vibe");
     }
     
     @Override
     protected Action<ServerHttpExchange> httpAction() {
         return server.httpAction();
     }
     
     @Override
     public Action<ServerWebSocket> wsAction() {
         return server.websocketAction();
     }
 });
