## Public methods

### equals

[**Added in Android UpsideDownCakePrivacySandbox**](https://developer.android.com/preview)  

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

Indicates whether some other object is "equal to" this one.


The `equals` method implements an equivalence relation
on non-null object references:

- It is *reflexive* : for any non-null reference value `x`, `x.equals(x)` should return `true`.
- It is *symmetric* : for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is *transitive* : for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
- It is *consistent* : for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
- For any non-null reference value `x`, `x.equals(null)` should return `false`.


The `equals` method for class `Object` implements
the most discriminating possible equivalence relation on objects;
that is, for any non-null reference values `x` and
`y`, this method returns `true` if and only
if `x` and `y` refer to the same object
(`x == y` has the value `true`).


Note that it is generally necessary to override the `hashCode`
method whenever this method is overridden, so as to maintain the
general contract for the `hashCode` method, which states
that equal objects must have equal hash codes.

| `boolean` | `true` if this object is the same as the obj argument; `false` otherwise. <br /> |

### getResumptionTokens

[**Added in Android UpsideDownCakePrivacySandbox**](https://developer.android.com/preview)  

```
public List<byte[]> getResumptionTokens ()
```

A list of resumption token byte arrays corresponding to training examples. The last
processed example's corresponding resumption token will be passed to
[TrainingExampleInput](https://developer.android.com/design-for-safety/privacy-sandbox/reference/adservices/ondevicepersonalization/TrainingExampleInput) to support resumption. The length of resumptionTokens should
match trainingExamples.

### getTrainingExamples

[**Added in Android UpsideDownCakePrivacySandbox**](https://developer.android.com/preview)  

```
public List<byte[]> getTrainingExamples ()
```

A list of training example byte arrays. The format is binary
seriazlied tf.Example proto by default. The maximum example size is 50KB to avoid hitting
Binder IPC size limit.

<br />

|                                                    Returns                                                    ||
|--------------------------------------------------------------------------|-------------------------------------|
| [List](https://developer.android.com/reference/java/util/List)`<byte[]>` | This value cannot be `null`. <br /> |

### hashCode

[**Added in Android UpsideDownCakePrivacySandbox**](https://developer.android.com/preview)  

```
public int hashCode ()
```

Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
[HashMap](https://developer.android.com/reference/java/util/HashMap).


The general contract of `hashCode` is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `equals(Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is *not* required that if two objects are unequal according to the [equals(java.lang.Object)](https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)) method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.


As much as is reasonably practical, the hashCode method defined
by class `Object` does return distinct integers for
distinct objects. (The hashCode may or may not be implemented
as some function of an object's memory address at some point
in time.)
