| * Observable field classes may be used instead of creating an Observable object: |
| * <pre><code>public class MyDataObject { |
| * public final ObservableShort age = new ObservableShort(); |
| * }</code></pre> |
| * Fields of this type should be declared final because bindings only detect changes in the |
| * field's value, not of the field itself. |
| * <p> |
| * This class is parcelable and serializable but callbacks are ignored when the object is |
| * parcelled / serialized. Unless you add custom callbacks, this will not be an issue because |
| * data binding framework always re-registers callbacks when the view is bound. |
