## Public methods
### describeContents
Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
fun describeContents(): Int
```
| Return ||
|----------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) | 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](https://developer.android.com/reference/kotlin/android/os/Parcelable.html#CONTENTS_FILE_DESCRIPTOR:kotlin.Int) |
### equals
Added in[API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
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 return`true`.
- It is*symmetric* : for any non-null reference values`x`and`y`,`x.equals(y)`should return`true`if and only if`y.equals(x)`returns`true`.
- It is*transitive* : for any non-null reference values`x`,`y`, and`z`, if`x.equals(y)`returns`true`and`y.equals(z)`returns`true`, then`x.equals(z)`should return`true`.
- It is*consistent* : for any non-null reference values`x`and`y`, multiple invocations of`x.equals(y)`consistently return`true`or consistently return`false`, provided no information used in`equals`comparisons on the objects is modified.
- For any non-null reference value`x`,`x.equals(null)`should return`false`.
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.
