This class holds JSON that will be passed into a JavaScript function during ad selection. Its contents are not used by[FLEDGE](https://developer.android.com/design-for-safety/privacy-sandbox/fledge)platform code, but are merely validated and then passed to the appropriate JavaScript ad selection function.

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

fun hashCode(): Int
```

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