Example 1

Project: spring-xd-master File: GPFDistServer.java View source code

private HttpServer<Buffer, Buffer> createProtocolListener() throws Exception {
    final Stream<Buffer> stream = Streams.wrap(processor).window(flushCount, flushTime, TimeUnit.SECONDS).flatMap(new Function<Stream<Buffer>, Publisher<Buffer>>() {

        @Override
        public Publisher<Buffer> apply(Stream<Buffer> t) {
            return t.reduce(new Buffer(), new BiFunction<Buffer, Buffer, Buffer>() {

                @Override
                public Buffer apply(Buffer prev, Buffer next) {
                    return prev.append(next);
                }
            });
        }
    }).process(RingBufferWorkProcessor.<Buffer>create("gpfdist-sink-worker", 8192, false));
    HttpServer<Buffer, Buffer> httpServer = NetStreams.httpServer(new Function<HttpServerSpec<Buffer, Buffer>, HttpServerSpec<Buffer, Buffer>>() {

        @Override
        public HttpServerSpec<Buffer, Buffer> apply(HttpServerSpec<Buffer, Buffer> server) {
            return server.codec(new GPFDistCodec()).listen(port);
        }
    });
    httpServer.get("/data", new ReactorChannelHandler<Buffer, Buffer, HttpChannel<Buffer, Buffer>>() {

        @Override
        public Publisher<Void> apply(HttpChannel<Buffer, Buffer> request) {

    });
