class LanguageReference in Drupal 10

Defines the 'language_reference' data type.

This serves as 'language' property of language field items and gets its value set from the parent, i.e. LanguageItem.

The plain value is the language object, i.e. an instance of \Drupal\Core\Language\Language. For setting the value the language object or the language code as string may be passed.
