```
public static final Creator<ParcelUuid> CREATOR
```

<br />

<br />

## Public constructors

### ParcelUuid

Added in [API level 5](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public ParcelUuid (UUID uuid)
```

Constructor creates a ParcelUuid instance from the given `https://developer.android.com/reference/java/util/UUID`.

<br />

| Parameters ||
|---|---|
| `uuid` | `UUID`: UUID <br /> |

## Public methods

### describeContents

Added in [API level 5](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 5](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean equals (Object object)
```

Compares this ParcelUuid to another object for equality. If `object` is not `null`, is a ParcelUuid instance, and all bits are equal, then `true` is returned.

<br />

| Parameters ||
|---|---|
| `object` | `Object`: the `Object` to compare to. This value may be `null`. <br /> |

| Returns ||
|---|---|
| `boolean` | `true` if this ParcelUuid is equal to `object` or `false` if not. <br /> |

### fromString

Added in [API level 5](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static ParcelUuid fromString (String uuid)
```

Creates a new ParcelUuid from a string representation of `https://developer.android.com/reference/java/util/UUID`.

<br />

| Parameters ||
|---|---|
| `uuid` | `String`: the UUID string to parse. <br /> |

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/os/ParcelUuid` | a ParcelUuid instance. <br /> |

| Throws ||
|---|---|
| `https://developer.android.com/reference/java/lang/IllegalArgumentException` | if `uuid` is not formatted correctly. |
| `https://developer.android.com/reference/java/lang/NullPointerException` | if `uuid` is `null`. |

### getUuid

Added in [API level 5](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public UUID getUuid ()
```

Get the `https://developer.android.com/reference/java/util/UUID` represented by the ParcelUuid.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/util/UUID` | UUID contained in the ParcelUuid. <br /> |

### hashCode

Added in [API level 5](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int hashCode ()
```

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by `https://developer.android.com/reference/java/util/HashMap`.

The general contract of `hashCode` is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is *not* required that if two objects are unequal according to the `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

<br />

<br />

| Returns ||
|---|---|
| `int` | a hash code value for this object. <br /> |

### toString

Added in [API level 5](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public String toString ()
```

Returns a string representation of the ParcelUuid For example: 0000110B-0000-1000-8000-00805F9B34FB will be the return value.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | a String instance. <br /> |

### writeToParcel

Added in [API level 5](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void writeToParcel (Parcel dest, 
                int flags)
```

Flatten this object in to a Parcel.

<br />

| Parameters ||
|---|---|
| `dest` | `Parcel`: The Parcel in which the object should be written. This value cannot be `null`. <br /> |
| `flags` | `int`: Additional flags about how the object should be written. May be 0 or `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE` |
