An observable class that holds a primitive int.
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 ObservableField<String> name = new ObservableField<String>();
public final ObservableInt age = new ObservableInt();
public final ObservableInt birthdayCount = new ObservableInt(age) {
@Override
public int get() { return 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. An parceled ObservableInt will lose its dependencies.
