### CREATOR

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)  
Also in [Ad Services Extensions 4](https://developer.android.com/sdkExtensions)   
Deprecated in [API level

public static final Creator<AdTechIdentifier> CREATOR
```

## Public methods

### describeContents

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)   
Deprecated in [API level
37](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 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)   
Deprecated in [API level
37](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

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

Compares this AdTechIdentifier to the specified object. The result is true if and only if the
argument is not null and is a AdTechIdentifier object with the same string form (obtained by
calling `https://developer.android.com/reference/android/adservices/common/AdTechIdentifier#toString()`). Note that this method will not perform any eTLD+1 normalization
so two AdTechIdentifier objects with the same eTLD+1 could be not equal if the String
representations of the objects was not equal.

<br />

| Parameters ||
|---|---|
| `o` | `Object`: The object to compare this AdTechIdentifier against <br /> |

| Returns ||
|---|---|
| `boolean` | true if the given object represents an AdTechIdentifier equivalent to this AdTechIdentifier, false otherwise <br /> |

### fromString

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)  
Also in [Ad Services Extensions 4](https://developer.android.com/sdkExtensions)   
Deprecated in [API level
37](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static AdTechIdentifier fromString (String source)
```

Construct an instance of this class from a String.

<br />

| Parameters ||
|---|---|
| `source` | `String`: A valid eTLD+1 domain of an ad buyer or seller. This value cannot be `null`. <br /> |

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/adservices/common/AdTechIdentifier` | An `https://developer.android.com/reference/android/adservices/common/AdTechIdentifier` object wrapping the given domain. This value cannot be `null`. <br /> |

### hashCode

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)   
Deprecated in [API level
37](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int hashCode ()
```

Returns a hash code corresponding to the string representation of this class obtained by
calling `https://developer.android.com/reference/android/adservices/common/AdTechIdentifier#toString()`. Note that this method will not perform any eTLD+1 normalization
so two AdTechIdentifier objects with the same eTLD+1 could have different hash codes if the
underlying string representation was different.

<br />

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

### toString

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)   
Deprecated in [API level
37](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public String toString ()
```

Returns a string representation of the object.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | The identifier in String form. This value cannot be `null`. <br /> |

### writeToParcel

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)   
Deprecated in [API level
37](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`: 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` |
