Class

ReferenceListTrait

Passes reference handling to DataReferenceDefinitionHalNormalizer.

Namespace

Drupal\schemata_json_schema\Normalizer\hal

Code

public function normalize($entity, $format = NULL, array $context = []) {

  /* @var $entity \Drupal\Core\TypedData\ListDataDefinitionInterface */

  // If this list does not wrap a reference, revert to standard JSON behavior.
  if (!$this
    ->isReferenceField($entity)) {
    return parent::normalize($entity, $format, $context);
  }

  // Unlike
  // Drupal\schemata_json_schema\Normalizer\json\ListDataDefinitionNormalizer,
  // this does not return the nested value into the property's 'items'
  // attribute. Instead it returns the normalized reference definition to be
  // merged at the normalized object root. This means the item definition
  // referred to below can choose to add new properties, required values, and
  // so on.
  $context['parent'] = $entity;
  return $this->serializer
    ->normalize($entity
    ->getItemDefinition(), $format, $context);
