### describeContents

Added in[API level 34](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[writeToParcel(android.os.Parcel, int)](https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)), the return value of this method must include the[CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR)bit.

### equals

Added in[API level 34](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[toString()](https://developer.android.com/design-for-safety/privacy-sandbox/reference/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.

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

| `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)  

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

Construct an instance of this class from a String.

|                                     Parameters                                     ||
|----------|--------------------------------------------------------------------------|
| `source` | `String`: A valid eTLD+1 domain of an ad buyer or seller or null. <br /> |

|                                                                                                                                                                  Returns                                                                                                                                                                  ||
|----------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| [AdTechIdentifier](https://developer.android.com/design-for-safety/privacy-sandbox/reference/adservices/common/AdTechIdentifier) | An[AdTechIdentifier](https://developer.android.com/design-for-safety/privacy-sandbox/reference/adservices/common/AdTechIdentifier)class wrapping the given domain or null if the input was null. <br /> |

### hashCode

Added in[API level 34](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[toString()](https://developer.android.com/design-for-safety/privacy-sandbox/reference/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)  

```
public String toString ()
```

Returns a string representation of the object. In general, the`toString`method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The`toString`method for class`Object`returns a string consisting of the name of the class of which the object is an instance, the at-sign character \``@`', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
>
> ```
>  getClass().getName() + '@' + Integer.toHexString(hashCode())
>  
> ```

<br />

|--------------------------------------------------------------------|-------------------------------------------------------------------|
| [String](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)  

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

Flatten this object in to a Parcel.
