It includes a constructor and the `onExpired()` method, which is triggered when a published message expires, either due to the time-to-live (TTL) elapsing or the user stopping Nearby actions for the app. Utilizing this callback is recommended to update application state when messages expire. It also inherits methods from the base `Object` class like `equals` and `toString`.\n"]]
