### equals

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

```
fun equals(other: Any?): Boolean
```

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/reference/kotlin/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.
