public function Fields::resolve in GraphQL 8.4

Resolves the list of fields for a given entity.

Respects the optional context parameters "bundle" and "field_types". If bundle context is set it resolves the fields only for that entity bundle. The same goes for field types when either base fields of configurable fields may be returned.

Parameters

\Drupal\Core\Entity\EntityTypeInterface $entity_definition: The entity type definition.

array|null $bundle_context: Bundle context.

string|null $field_types_context: Field types context.

\Drupal\graphql\GraphQL\Execution\FieldContext $field_context: Field context.
