public function FieldConfig::__construct in Drupal 9

Same name and namespace in other branches

1. 8 core/modules/field/src/Entity/FieldConfig.php \Drupal\field\Entity\FieldConfig::__construct()

Constructs a FieldConfig object.

In most cases, Field entities are created via FieldConfig::create($values), where $values is the same parameter as in this constructor.

Parameters

array $values: An array of field properties, keyed by property name. The storage associated with the field can be specified either with:

• field_storage: the FieldStorageConfigInterface object,

or by referring to an existing field storage in the current configuration with:

• field_name: The field name.
• entity_type: The entity type.

Additionally, a 'bundle' property is required to indicate the entity bundle to which the field is attached to. Other array elements will be used to set the corresponding properties on the class; see the class property documentation for details.

string $entity_type: (optional) The entity type on which the field should be created. Defaults to "field_config".
