### 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.

| `int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either`0`or[CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR) <br /> |

### equals

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

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

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/design-for-safety/privacy-sandbox/reference/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.

|-----------|-------------------------------------------------------------------------------------------------------------------------|
| `boolean` | true if the given object represents an AdSelectionSignals equivalent to this AdSelectionSignals, 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 AdSelectionSignals fromString (String source)
```

Creates an AdSelectionSignals from a given JSON in String form.

|----------|-----------------------------------------------------------------------------------------------------------|
| `source` | `String`: Any valid JSON string to create the AdSelectionSignals with. This value cannot be`null`. <br /> |

|                                                                                                             Returns                                                                                                              ||
|--------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------|
| [AdSelectionSignals](https://developer.android.com/design-for-safety/privacy-sandbox/reference/adservices/common/AdSelectionSignals) | An AdSelectionSignals object wrapping the given String. This value cannot be`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/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.

<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 String form of the JSON wrapped by this class. 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.
