public static DataDefinitionInterface::createFromDataType($data_type) Creates a new data definition object. This method is typically used by \Drupal\Core\TypedData\TypedDataManager::createDataDefinition() to build a definition object for an arbitrary data type. When the definition class is known, it is recommended to directly use the static create() method on that class instead; e.g.: $map_definition = \Drupal\Core\TypedData\MapDataDefinition::create(); Parameters string $data_type: The dat

public DataDefinitionInterface::addConstraint($constraint_name, $options = NULL) Adds a validation constraint. See \Drupal\Core\TypedData\DataDefinitionInterface::getConstraints() for details. Parameters string $constraint_name: The name of the constraint to add, i.e. its plugin id. array|null $options: The constraint options as required by the constraint plugin, or NULL.

Interface for data definitions. Data definitions are used to describe data based upon available data types. For example, a plugin could describe its parameters using data definitions in order to specify what kind of data is required for it. Definitions that describe lists or complex data have to implement the respective interfaces, such that the metadata about contained list items or properties can be retrieved from the definition.
