protected RecursiveContextualValidator::validateNode(TypedDataInterface $data, $constraints = NULL, $is_root_call = FALSE)
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
