3. 11.x core/modules/jsonapi/src/IncludeResolver.php \Drupal\jsonapi\IncludeResolver::resolveIncludeTree()

Receives a tree of include field names and resolves resources for it.

This method takes a tree of relationship field names and JSON:API Data object. For the top-level of the tree and for each entity in the collection, it gets the target entity type and IDs for each relationship field. The method then loads all of those targets and calls itself recursively with the next level of the tree and those loaded resources.

Parameters

array $include_tree: The include paths, represented as a tree.

\Drupal\jsonapi\JsonApiResource\Data $data: The entity collection from which includes should be resolved.

\Drupal\jsonapi\JsonApiResource\Data|null $includes: (Internal use only) Any prior resolved includes.

Return value

\Drupal\jsonapi\JsonApiResource\Data A JSON:API Data of included items.

Throws

\Drupal\Component\Plugin\Exception\PluginNotFoundException Thrown if an included entity type doesn't exist.

\Drupal\Component\Plugin\Exception\InvalidPluginDefinitionException Thrown if a storage handler couldn't be loaded.
