Using Reserved names with realm.io / Android

Imagine there's an API that returns something like this:

       "names":{  
           "short":"xxx",
           "medium":null,
           "long":"xxxxxx"
        },

(just an example)

Then imagine that you have a model to represent the above that looks like this:

public class Names extends RealmObject {
   private String short;
   private String medium;
   private String long;
   // getters/setters omitted for clarity
}

There's a problem, since both short and long are reserved keywords in Java.

Other ORMs present an annotation (usually @Key("othername")) to deal with these scenarios.

What would be realm.io's solution?

Thanks!

Christian from Realm here. Our JSON support is still pretty simple, but we plan to address issues like those in the next iteration. Currently you have two options: Either convert the JSON to JSONObject and manually map the fields in a static methods like this:

public class Names extends RealmObject {

  ...

  public static Names fromJson(JSONObject json) {
    Names names = new Names();
    names.setShortField(json.getString("short");
    return names;
  }
}

or alternatively if you don't mind including other 3rd party libraries, you can use GSON which has a @SerializedName annotation.
