Subclasses of the Updater class to update Drupal core knows how to update. At this time, only modules and themes are supported.

class ThemeUpdater extends Updater implements DrupalUpdaterInterface {

  /**
   * Return the directory where a theme should be installed.
   *
   * If the theme is already installed, drupal_get_path() will return
   * a valid path and we should install it there (although we need to use an
   * absolute path, so we prepend DRUPAL_ROOT). If we're installing a new
   * theme, we always want it to go into sites/all/themes, since that's
   * where all the documentation recommends users install their themes, and
   * there's no way that can conflict on a multi-site installation, since
   * the Update manager won't let you install a new theme if it's already
   * found on your system, and if there was a copy in sites/all, we'd see it.
