ObservableByte

public class ObservableByte
extends BaseObservable implements Parcelable, Serializable

java.lang.Object
   ↳ android.databinding.BaseObservable
     ↳ android.databinding.ObservableByte


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(); }
     };
 }
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 ObservableByte will lose its dependencies.

Public constructors

ObservableByte

ObservableByte (byte value)

Creates an ObservableByte with the given initial value.

Parameters
value byte: the initial value for the ObservableByte

ObservableByte

ObservableByte ()

Creates an ObservableByte with the initial value of 0.

ObservableByte

ObservableByte (Observable... dependencies)

Creates an ObservableByte that depends on dependencies. Typically, ObservableFields are passed as dependencies. When any dependency notifies changes, this ObservableByte also notifies a change.

Parameters
dependencies Observable: The Observables that this ObservableByte depends on.

Public methods

describeContents

int describeContents ()

Returns
int

get

byte get ()

Returns
byte the stored value.

set

void set (byte value)

Set the stored value.

Parameters
value byte: The new value

writeToParcel

void writeToParcel (Parcel dest, 
                int flags)

Parameters
dest Parcel

flags int
