Same name and namespace in other branches
  1. 9 core/lib/Drupal/Core/Field/FieldConfigInterface.php \Drupal\Core\Field\FieldConfigInterface

Defines an interface for configurable field definitions.

This interface allows both configurable fields and overridden base fields to share a common interface. The interface also extends ConfigEntityInterface to ensure that implementations have the expected save() method.
