1. 8 core/modules/hal/src/Normalizer/FieldItemNormalizer.php \Drupal\hal\Normalizer\FieldItemNormalizer::createTranslatedInstance()

Get a translated version of the field item instance.

To indicate that a field item applies to one translation of an entity and not another, the property path must originate with a translation of the entity. This is the reason for using target_instances, from which the property path can be traversed up to the root.

Parameters

\Drupal\Core\Field\FieldItemInterface $item: The untranslated field item instance.

$langcode: The langcode.

Return value

\Drupal\Core\Field\FieldItemInterface The translated field item instance.
