Same name and namespace in other branches

1. 8 core/lib/Drupal/Core/Extension/module.api.php \hook_updater_info()
2. 7 modules/system/system.api.php \hook_updater_info()

Provide information on Updaters (classes that can update Drupal).

Drupal\Core\Updater\Updater is a class that knows how to update various parts of the Drupal file system, for example to update modules that have newer releases, or to install a new theme.

Return value

An associative array of information about the updater(s) being provided. This array is keyed by a unique identifier for each updater, and the values are subarrays that can contain the following keys:

• class: The name of the PHP class which implements this updater.
• name: Human-readable name of this updater.
• weight: Controls what order the Updater classes are consulted to decide which one should handle a given task. When an update task is being run, the system will loop through all the Updater classes defined in this registry in weight order and let each class respond to the task and decide if each Updater wants to handle the task. In general, this doesn't matter, but if you need to override an existing Updater, make sure your Updater has a lighter weight so that it comes first.
