### Gérer les valeurs de retour { #return-values }

Elles peuvent retourner des valeurs ou non, ces valeurs ne seront pas utilisées.

Vous pouvez donc réutiliser une dépendance normale (qui retourne une valeur) que vous utilisez déjà ailleurs ; même si la valeur n'est pas utilisée, la dépendance sera exécutée :

   * returned by {@link CacheLoader#loadAll} will be stored in the cache, over-writing any
   * previously cached values. This method will throw an exception if {@link CacheLoader#loadAll}
   * returns {@code null}, returns a map containing null keys or values, or fails to return an entry
   * for each requested key.
   *
   * <p>Note that duplicate elements in {@code keys}, as determined by {@link Object#equals}, will
   * be ignored.
