LanguageDefault

Provides a simple get and set wrapper to the default language object.

The default language must be provided without dependencies since it is both configured and a dependency of the configuration system. The LanguageDefault object is a container service. The default values are stored on the container by \Drupal\Core\DrupalKernel::buildContainer(). This allows services to override this parameter in a ServiceProvider, for example, \Drupal\language\LanguageServiceProvider::alter().
