class DeprecatedAutoloadAccess

Same name and namespace in other branches
  1. 11.x core/lib/Drupal/Core/Runtime/DeprecatedAutoloadAccess.php \Drupal\Core\Runtime\DeprecatedAutoloadAccess

Provides deprecation errors when the classloader is accessed.

Allows making the classloader available in the `$GLOBAL['autoloader']` but will trigger errors if any of its methods are accessed in this way.

Since the path to our autoloader depends on where we're installed (root/core vs root/vendor/drupal/core) we lazily traverse the filesystem for the autoloader only if it's actually requested.
