- * Static Service Container wrapper.
- *
- * Generally, code in Drupal should accept its dependencies via either
- * constructor injection or setter method injection. However, there are cases,
- * particularly in legacy procedural code, where that is infeasible. This
- * class acts as a unified global accessor to arbitrary services within the
- * system in order to ease the transition from procedural code to injected OO
- * code.
- *
- * The container is built by the kernel and passed in to this class which stores
- * it statically. The container always contains the services from
- * \Drupal\Core\CoreServiceProvider, the service providers of enabled modules and any other
- * service providers defined in $GLOBALS['conf']['container_service_providers'].
- *
- * This class exists only to support legacy code that cannot be dependency
- * injected. If your code needs it, consider refactoring it to be object
- * oriented, if possible. When this is not possible, for instance in the case of
- * hook implementations, and your code is more than a few non-reusable lines, it
- * is recommended to instantiate an object implementing the actual logic.
- *
- * @code
- * // Legacy procedural code.
- * function hook_do_stuff() {
- * $lock = lock()->acquire('stuff_lock');
- * // ...
- * }
- *
- * // Correct procedural code.
- * function hook_do_stuff() {
- * $lock = \Drupal::lock()->acquire('stuff_lock');
- * // ...
- * }
- *
- * // The preferred way: dependency injected code.
- * function hook_do_stuff() {
- * // Move the actual implementation to a class and instantiate it.
- * $instance = new StuffDoingClass(\Drupal::lock());
- * $instance->doStuff();
- *
- * // Or, even better, rely on the service container to avoid hard coding a
- * // specific interface implementation, so that the actual logic can be
- * // swapped. This might not always make sense, but in general it is a good
- * // practice.
