Interface MediaSupport

All Known Implementing Classes:
DefaultMediaSupport, JacksonSupport, JsonbSupport, JsonpSupport, MultiPartSupport
public interface MediaSupport
Service used to register readers and writers to the respective context.

MediaSupport instances can be used with WebServer and WebClient to register readers and writer. Each of these have method addMediaSupport(), which will add corresponding support.


WebServer example usage: 

 WebServer.builder()
          .addMediaSupport(JsonbSupport.create())
          .build();
WebClient example usage: 

 WebClient.builder()
          .addMediaSupport(JacksonSupport.create())
          .build();
If you need to register MediaSupport on the request or response, you will need to register them to the corresponding context.
Example request reader registration: 

 Routing.builder()
        .get("/foo", (res, req) -> {
            MessageBodyReadableContent content = req.content();
            content.registerReader(JsonbSupport.create())
            content.as(String.class)
                   .thenAccept(System.out::print);
        })
Example response writer registration: 

 Routing.builder()
        .get("/foo", (res, req) -> {
           MessageBodyWriterContext writerContext = res.writerContext();
           writerContext.registerWriter(JsonbSupport.create())
           res.send("Example entity");
        })
