Defines a data type annotation object. The typed data API allows modules to support any kind of data based upon pre-defined primitive types and interfaces for complex data and lists. Defined data types may map to one of the pre-defined primitive types in \Drupal\Core\TypedData\Primitive or may be complex data types, containing on or more data properties. Typed data objects for complex data types have to implement the \Drupal\Core\TypedData\ComplexDataInterface. Further interface that may be imp

public DataReferenceTargetDefinition::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(
