public function EntityLanguage::onUnserializeContentField in Acquia Content Hub 8.2

Handles language fields and the default_langcode field values.

This is actually a tricky bit of code that throws away language values for the "langcode" entity type key when present because Drupal will do its own determination of things like "default_langcode" if values are present in that field. Rather than allow this, we throw it away and handle defaults manually.

Parameters

\Drupal\acquia_contenthub\Event\UnserializeCdfEntityFieldEvent $event: The unserialize event.
