@JsType(isNative = true, name = "Object", namespace = JsPackage.GLOBAL)
public class Result {
String[] columns; // or JsArrayLike<String>
JsPropertyMap<String> data;
}
That should be enough (and much much simpler/shorter than with JSNI).
Migrating a JSNI getData(String):String to JsInterop would be quite easy
too:
@JsType(isNative = true, name = "Object", namespace = JsPackage.GLOBAL)
public class Result {
@JsProperty public native String[] getColumns();
@JsOverlay public String getData(String key) {
return getData().get(key);
}
@JsProperty private native JsPropertyMap<String> getData();
}
