public static EntityReferenceFieldItemList::processDefaultValue($default_value, FieldableEntityInterface $entity, FieldDefinitionInterface $definition)
Processes the default value before being applied.
Defined or configured default values of a field might need some processing in order to be a valid runtime value for the field type; e.g., a date field could process the defined value of 'NOW' to a valid date.
Parameters
array $default_value: The unprocessed default value defined for the field, as a numerically indexed array of items, each item being an array of property/value pairs.
\Drupal\Core\Entity\FieldableEntityInterface $entity: The entity for which the default value is generated.
\Drupal\Core\Field\FieldDefinitionInterface $definition: The definition of the field.
Return value
array The return default value for the field.
