Namespace Drupal\Core\Updater Code public static function canUpdateDirectory($directory);

Defines an interface for a class which can update a Drupal project. An Updater currently serves the following purposes: It can take a given directory, and determine if it can operate on it. It can move the contents of that directory into the appropriate place on the system using FileTransfer classes. It can return a list of "next steps" after an update or install. In the future, it will most likely perform some of those steps as well. Hierarchy interface \Drupal\Core\Updater\UpdaterInterface

Defines a child class of Drupal\Core\Updater\UpdaterException that indicates a Drupal\Core\FileTransfer\FileTransfer exception. We have to catch Drupal\Core\FileTransfer\FileTransfer exceptions and wrap those in t(), since Drupal\Core\FileTransfer\FileTransfer is so low-level that it doesn't use any Drupal APIs and none of the strings are translated. Hierarchy class \Drupal\Core\Updater\UpdaterException extends \Exceptionclass \Drupal\Core\Updater\UpdaterFileTransferException File core/lib/

Defines a Exception class for the Drupal\Core\Updater\Updater class hierarchy. This is identical to the base Exception class, we just give it a more specific name so that call sites that want to tell the difference can specifically catch these exceptions and treat them differently.
