An observable class that holds a primitive byte.
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 ObservableByte flags = new ObservableByte();
public final ObservableByte otherFlags = new ObservableByte();
public final ObservableByte mergedFlags = new ObservableByte(flags, otherFlags) {
@Override
public byte get() { return flags.get() | otherFlags.get(); }
};
}
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 ObservableByte will lose its dependencies.
