Pero por defecto, todo **"simplemente funciona"**.

### Validación

* Validación para la mayoría (¿o todas?) de los **tipos de datos** de Python, incluyendo:
    * Objetos JSON (`dict`).
    * Array JSON (`list`) definiendo tipos de elementos.

- Added reconstruction of SELinux mount context after kubelet restart. Feature `SELinuxMountReadWriteOncePod` is now fully implemented and kubelet does not lose its cache of SELinux contexts after kubelet process restart. ([#113596](https://github.com/kubernetes/kubernetes/pull/113596), [@jsafrane](https://github.com/jsafrane))

Estos ejemplos son intencionalmente simples, pero muestran cómo funciona todo.

En los capítulos sobre seguridad, hay funciones utilitarias que se implementan de esta misma manera.

Si entendiste todo esto, ya sabes cómo funcionan por debajo esas herramientas de utilidad para seguridad.

 * @since 15.0
 * @deprecated Use {@link com.google.common.graph.Traverser} instead. All instance methods have
 *     their equivalent on the result of {@code Traverser.forTree(tree)} where {@code tree}
 *     implements {@code SuccessorsFunction}, which has a similar API as {@link #children} or can be
 *     the same lambda function as passed into {@link #using(Function)}.
 *     <p>This class is scheduled to be removed in October 2019.
