  • describeContents

    public int describeContents()

    Parcelable interface methods

    Specified by:

    describeContents in interface Parcelable

    Returns:

    a bitmask indicating the set of special object types marshalled by the Parcelable.

  • writeToParcel

    public void writeToParcel(Parcel out,
                     int flags)

    Write this point to the specified parcel. To restore a point from a parcel, use readFromParcel()

    Specified by:

    writeToParcel in interface Parcelable

    Parameters:

    out - The parcel to write the point's coordinates into

    flags - Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE.

  • readFromParcel

    public void readFromParcel(Parcel in)

    Set the point's coordinates from the data stored in the specified parcel. To write a point to a parcel, call writeToParcel().

    Parameters:

    in - The parcel to read the point's coordinates from
