<br />

## Public methods

### describeContents

Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public 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 `https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)`, the return value of this method must include the `https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` bit.

<br />

| Returns ||
|---|---|
| `int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or - `https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` |

### equals

Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean equals (Object o)
```

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.

<br />

| Parameters ||
|---|---|
| `o` | `Object`: the reference object with which to compare. <br /> |

| Returns ||
|---|---|
| `boolean` | `true` if this object is the same as the obj argument; `false` otherwise. <br /> |

public CharSequence getDescription ()
