public function FieldConfig::__construct in Drupal 8

Same name and namespace in other branches

9 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.
