public static function ListDataDefinition::createFromItemType

public static ListDataDefinition::createFromItemType($item_type)

Creates a new list data definition for items of the given data type.

This method is typically used by \Drupal\Core\TypedData\TypedDataManager::createListDataDefinition() to build a definition object for an arbitrary item type. When the definition class is known, it is recommended to directly use the static create() method on that class instead; e.g.:

  $list_definition = \Drupal\Core\TypedData\ListDataDefinition::create('string');

Parameters

string $item_type: The item type, for which a list 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 lists of 'field_item:* data types.
