public function EntityFieldManager::getFieldStorageDefinitions

public EntityFieldManager::getFieldStorageDefinitions($entity_type_id)

Gets the field storage definitions for a content entity type.

This returns all field storage definitions for base fields and bundle fields of an entity type. Note that field storage definitions of a base field equal the full base field definition (i.e. they implement FieldDefinitionInterface), while the storage definitions for bundle fields may implement FieldStorageDefinitionInterface only.

Parameters

string $entity_type_id: The entity type ID. Only content entities are supported.

Return value

\Drupal\Core\Field\FieldStorageDefinitionInterface[] The array of field storage definitions for the entity type, keyed by field name.

Overrides EntityFieldManagerInterface::getFieldStorageDefinitions
