public static DataReferenceDefinition::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.:
1 | $map_definition = \Drupal\Core\TypedData\MapDataDefinition::create(); |
Parameters
string $data_type: The data type, for which a data definition should be created.
Return value
static
Throws
\InvalidArgumentException If an unsupported data type gets passed to the class; e.g., 'string' to a definition class handling 'entity:* data types.
