An observable class that holds a primitive short.
Observable field classes may be used instead of creating an Observable object. It can also create a calculated field, depending on other fields:
public class MyDataObject {
public final ObservableShort age = new ObservableShort();
public final ObservableShort birthdayCount = new ObservableShort(age) {
@Override
public short get() { return (short)(age.get() + 1); }
};
}
Fields of this type should be declared final because bindings only detect changes in the
field's value, not of the field itself.
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. A parceled ObservableBoolean will lose its dependencies.
