protected function FieldResolver::resourceTypesAreTraversable in JSON:API 8

Same name and namespace in other branches

1. 8.2 src/Context/FieldResolver.php \Drupal\jsonapi\Context\FieldResolver::resourceTypesAreTraversable()

Whether the given resources can be traversed to other resources.

@todo This class shouldn't be aware of entity types and their definitions. Whether a resource can have relationships to other resources is information we ought to be able to discover on the ResourceType. However, we cannot reliably determine this information with existing APIs. Entities may be backed by various storages that are unable to perform queries across references and certain storages may not be able to store references at all.

Parameters

\Drupal\jsonapi\ResourceType\ResourceType[] $resource_types: The resources types to evaluate.

Return value

bool TRUE if any one of the given resource types is traversable.
