## Actualizar la App con Múltiples Modelos { #update-the-app-with-multiple-models }

Ahora vamos a **refactorizar** un poco esta aplicación para aumentar la **seguridad** y la **versatilidad**.

Si revisas la aplicación anterior, en la interfaz verás que, hasta ahora, permite al cliente decidir el `id` del `Hero` a crear. 😱

    public ActionResponse getResponse(final SsoResponseType responseType) {
        return null;
    }

    /**
     * Performs logout for the specified user.
     *
     * SPNEGO authentication relies on the underlying Kerberos infrastructure
     * for session management, so no specific logout URL is provided.
     *
     * @param user The user to logout

    ```kotlin
    if (response.responseCount >= 3) {
      return null // If we've failed 3 times, give up.
    }
    ```

    This above code relies on this `responseCount` extension val:

    ```kotlin
    val Response.responseCount: Int
      get() = generateSequence(this) { it.priorResponse }.count()
    ```

        List<E> castedList = (List<E>) list;
        return new RegularImmutableList<E>(castedList);
    }
  }

  /**
   * Views the array as an immutable list. The array must have only {@code E} elements.
   *
   * <p>The array must be internally created.

      if (get() == RunningState.CANCELLED) {
        delegate = null;
        sequencer = null;
        return;
      }

**FastAPI**가 어떻게 사용되고 있는지, 어떤 점이 마음에 들었는지, 어떤 프로젝트/회사에서 사용하고 있는지 등에 대해 듣고 싶습니다.

Si revisas el "administrador de tareas" o "monitor del sistema" (o herramientas similares) en tu sistema operativo, podrás ver muchos de esos procesos en ejecución.
