1. 9 core/lib/Drupal/Core/TypedData/Validation/RecursiveContextualValidator.php \Drupal\Core\TypedData\Validation\RecursiveContextualValidator::validateNode()

Validates a Typed Data node in the validation tree.

If no constraints are passed, the data is validated against the constraints specified in its data definition. If the data is complex or a list and no constraints are passed, the contained properties or list items are validated recursively.

Parameters

\Drupal\Core\TypedData\TypedDataInterface $data: The data to validated.

\Symfony\Component\Validator\Constraint[]|null $constraints: (optional) If set, an array of constraints to validate.

bool $is_root_call: (optional) Whether its the most upper call in the type data tree.

Return value

$this
