ObservableDouble

public class ObservableDouble
extends BaseObservable implements Parcelable, Serializable

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


An observable class that holds a primitive double.

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

public class MyDataObject {
     public final ObservableDouble temperature = new ObservableDouble();
 }
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.

Public constructors

ObservableDouble

ObservableDouble (double value)

Creates an ObservableDouble with the given initial value.

Parameters
value double: the initial value for the ObservableDouble

ObservableDouble

ObservableDouble ()

Creates an ObservableDouble with the initial value of 0.

Public methods

describeContents

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.

get

double get ()

Returns
double the stored value.

set

void set (double value)

Set the stored value.

Parameters
value double

writeToParcel

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.
