Value: 4TRACK_CHANGE_REASON_INITIAL
static val TRACK_CHANGE_REASON_INITIAL: Int
Track change reason for initial state.
Value: 2TRACK_CHANGE_REASON_MANUAL

Value: 0Public methods
describeContents
fun describeContents(): Int
| Return | |
|---|---|
Int | 
            a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR | 
          
equals
fun equals(other: Any?): Boolean
Indicates whether some other object is "equal to" this one.
 The equals method implements an equivalence relation on non-null object references: 
- It is reflexive: for any non-null reference value 
x,x.equals(x)should returntrue. - It is symmetric: for any non-null reference values 
xandy,x.equals(y)should returntrueif and only ify.equals(x)returnstrue. - It is transitive: for any non-null reference values 
x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue. - It is consistent: for any non-null reference values 
xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons on the objects is modified. - For any non-null reference value 
x,x.equals(null)should returnfalse. 
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
