interface VersionPurgerAdvisorInterface

    /**

     *
     * @param PurgeableVersionList $versionList
     *
     * @return bool
     */
    public function supports(PurgeableVersionList $versionList);

    /**

     *
     * @return PurgeableVersionList
     */
    public function isPurgeable(PurgeableVersionList $versionList): PurgeableVersionList;
}

example need to be updated.
