JSON: Treat many objects as array of object

Question

I have a JSON Like this

{ "video":{  
        "video_3745":{  },
        "video_3437":{  },
        "video_3471":{  },
        "video_4114":{  }
      }
}

In which every "video_xxxx" is of the SAME type. Is there a way to treat the "video" field as an array of that type? I need to iterate over all the videos, but the API is not sending them in an array, and I don't know how to model a class to receive this JSON without having to manually specify all the field names...

does GSON or LoganSquare have anything to help me out with this?

Try something like this

JSONObject video= json.getJSONObject("video"); // json is the whole response
Iterator x = video.keys();
JSONArray jsonArray = new JSONArray();

while (x.hasNext()){
    String key = (String) x.next();
    jsonArray.put(video.get(key));
}

You can't treat them as an array, but with the org.json.JSONObject class you can get the list of keys and iterate over them. I believe in GSON the JsonObject.entrySet method will allow something similar.
