### Création d'un `Enum`

Importez `Enum` et créez une sous-classe qui hérite de `str` et `Enum`.

En héritant de `str` la documentation sera capable de savoir que les valeurs doivent être de type `string` et pourra donc afficher cette `Enum` correctement.

Créez ensuite des attributs de classe avec des valeurs fixes, qui seront les valeurs autorisées pour cette énumération.

            assertNotNull(
                    SearchEngineUtil.class.getMethod("getXContentBuilderOutputStream", XContentBuilderCallback.class, MediaType.class));
            assertNotNull(SearchEngineUtil.class.getMethod("getXContentOutputStream", ToXContent.class, MediaType.class));
            assertNotNull(SearchEngineUtil.class.getMethod("scroll", String.class, java.util.function.Function.class));

/// info | Información

`File` es una clase que hereda directamente de `Form`.

Pero recuerda que cuando importas `Query`, `Path`, `File` y otros desde `fastapi`, esos son en realidad funciones que devuelven clases especiales.
