class LocaleDefaultConfigStorage in Zircon Profile 8

Same name and namespace in other branches
  1. 8.0 core/modules/locale/src/LocaleDefaultConfigStorage.php \Drupal\locale\LocaleDefaultConfigStorage

Provides access to default configuration for locale integration.

Allows unified access to default configuration from one of three sources:

  • Required default configuration (config/install/*)
  • Optional default configuration (config/optional/*)
  • Predefined languages mocked as default configuration (list defined in LocaleConfigManagerInterface::getStandardLanguageList())

These sources are considered equal in terms of how locale module interacts with them for translation. Their translatable source strings are exposed for interface translation and participate in remote translation updates.
