public class ObservableLong
extends BaseObservable
implements Parcelable, Serializable
java.lang.Object | ||
↳ | android.databinding.BaseObservable | |
↳ | android.databinding.ObservableLong |
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();
}
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.

ObservableLong (long value)
Creates an ObservableLong with the given initial value.
Parameters | |

value |
long : the initial value for the ObservableLong |
ObservableLong ()
Creates an ObservableLong with the initial value of 0L
.
int describeContents ()
Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(Parcel, int)
, the return value of this method must include the CONTENTS_FILE_DESCRIPTOR
bit.
Returns | |
---|---|
int |
a bitmask indicating the set of special object types marshaled by this Parcelable object instance. |
long get ()
Returns | |
---|---|
long |
the stored value. |
void set (long value)
Set the stored value.
Parameters | |
---|---|

void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
dest |
Parcel : The Parcel in which the object should be written. |
flags |
int : Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE . |
