Re: Complex JSON and overlay types

Thanks. I try it, but I don't undestand how does it works... Do you have simple examples or tutorials?

 

I try to do it:

interface Person {
   Names getNames();
   String getStyle();
 }

 interface Names {
   // Other properties, as above
  String getProp1();
  String getProp2();
  String getProp3();

 }

 // Declare the factory type
 interface MyFactory extends AutoBeanFactory {
   AutoBean<Names> names();
   AutoBean<Person> person();
 }

public class HelloWorld implements IsWidget,EntryPoint {
 
 
  public Widget asWidget() {
   String url="data.json";
   RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, url);
     //builder.setHeader("Access-Control-Allow-Origin", "*");
    
     try {
       Request response = builder.sendRequest(null, new RequestCallback() {
         public void onError(Request request, Throwable exception) {
           // Code omitted for clarity
         }

         public void onResponseReceived(Request request, Response response) {
           MyFactory factory = GWT.create(MyFactory.class);
          
          AutoBean<Person> bean = AutoBeanCodex.decode(factory, Person.class, response.getText());
          
          System.out.println("oui "+ bean.as().getNames());
          

         }

       });
     } catch (RequestException e) {
     }
  return null;
  
   }

@Override
public void onModuleLoad() {
 
 asWidget();
}
 
}

 

I get null. What do you think?

 

I'm still interested by a method with overlay type (=> Javascript), just to get "Jack" and "John" in  {"records": [{"names": {"John": ["50", "H", "US"], "Jack": ["50", "H", "US"]}, "style": "TR"}]}.

Hi everybody,

 

I want to read this kind of JSON with GWT:

 

{"records": [{"names": {"John": ["50", "H", "US"], "Jack": ["50", "H", "US"]}, "style": "TR"}]}

I use overlay for that.

If I use that, I get "TR":

 public final native String getStyle()
     /*-{
         return this.records[0].style;
     }-*/;

So, it's work. Now I want to get John and the list 50,H,US. If I use that I get null:

public final native String getNames(String i)
     /*-{
         return this.records[0].names[i];
     }-*/;

For the same thing, I try to do that and I get no result: (json is the of my class which is extended by JavaScriptObject)

       public final native JsArray<json> getArray(String key) /*-{
        return this[key] ? this[key] : new Array();
    }-*/;

and

result.getArray("names").toString()

 

Have you any idea to do what I want?

Thank you in advance !
