ObservableLong

Class Overview

An observable class that holds a primitive long.

Observable field classes may be used instead of creating an Observable object:

public class MyDataObject {
     public final ObservableLong friendCount = new ObservableLong();
 }

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.

Summary

[Expand] Inherited Constants

From interface android.os.Parcelable int CONTENTS_FILE_DESCRIPTOR Bit masks for use with describeContents(): each bit represents a kind of object considered to have potential special significance when marshalled. int PARCELABLE_WRITE_RETURN_VALUE Flag for use with writeToParcel(Parcel, int): the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)".

[Expand] Inherited Methods
From class android.databinding.BaseObservable synchronized void addOnPropertyChangedCallback(Observable.OnPropertyChangedCallback callback) Adds a callback to listen for changes to the Observable. synchronized void notifyChange() Notifies listeners that all properties of this instance have changed. void notifyPropertyChanged(int fieldId) Notifies listeners that a specific property has changed. synchronized void removeOnPropertyChangedCallback(Observable.OnPropertyChangedCallback callback) Removes a callback from those listening for changes.
From class java.lang.Object Object clone() Creates and returns a copy of this Object. boolean equals(Object o) Compares this instance with the specified object and indicates if they are equal. void finalize() Invoked when the garbage collector has detected that this instance is no longer reachable. final Class<?> getClass() Returns the unique instance of Class that represents this object's class. int hashCode() Returns an integer hash code for this object. final void notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up. final void notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up. String toString() Returns a string containing a concise, human-readable description of this object. final void wait() Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object. final void wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires. final void wait(long millis) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
From interface android.databinding.Observable abstract void addOnPropertyChangedCallback(Observable.OnPropertyChangedCallback callback) Adds a callback to listen for changes to the Observable. abstract void removeOnPropertyChangedCallback(Observable.OnPropertyChangedCallback callback) Removes a callback from those listening for changes.
From interface android.os.Parcelable abstract int describeContents() Describe the kinds of special objects contained in this Parcelable's marshalled representation. abstract void writeToParcel(Parcel dest, int flags) Flatten this object in to a Parcel.
