Class JsonHandler<B>

java.lang.Object
dev.relism.flash.models.RequestHandler

dev.relism.flash.ext.jackson.JacksonHandler<B>
dev.relism.flash.ext.jackson.json.JsonHandler<B>
public abstract class JsonHandler<B> extends dev.relism.flash.ext.jackson.JacksonHandler<B>
A handler that takes a JSON body of one type. 

 @POST("/users")
 public final class CreateUser extends JsonHandler<NewUser> {
     @Inject private UserService users;

     @Override protected Object handle(Request req, Response res, NewUser body) {
         return users.create(body);
     }
 }

The body is read off the request stream, verified against the constraints its type declares, and handed over. A malformed body is a 400, a body that breaks a constraint is a 422, and neither ever reaches the handler. The published OpenAPI document describes the same type.
