File core/lib/Drupal/Core/TypedData/DataDefinitionInterface.php, line 55 Class DataDefinitionInterface Interface for data definitions. Namespace Drupal\Core\TypedData Code public function getDataType();

public DataDefinitionInterface::getConstraints() Returns an array of validation constraints. The validation constraints of a definition consist of any for it defined constraints and default constraints, which are generated based on the definition and its data type. See \Drupal\Core\TypedData\TypedDataManager::getDefaultConstraints(). Constraints are defined via an array, having constraint plugin IDs as key and constraint options as values, e.g. $constraints = array( 'Range' => array('min'

public DataDefinitionInterface::getConstraint($constraint_name) Returns a validation constraint. See \Drupal\Core\TypedData\DataDefinitionInterface::getConstraints() for details. Parameters string $constraint_name: The name of the constraint, i.e. its plugin id. Return value array A validation constraint definition which can be used for instantiating a \Symfony\Component\Validator\Constraint object.
