public static function Term::bundleFieldDefinitions in Drupal 9

Same name and namespace in other branches

8 core/modules/taxonomy/src/Entity/Term.php \Drupal\taxonomy\Entity\Term::bundleFieldDefinitions()

Provides field definitions for a specific bundle.

This function can return definitions both for bundle fields (fields that are not defined in $base_field_definitions, and therefore might not exist on some bundles) as well as bundle-specific overrides of base fields (fields that are defined in $base_field_definitions, and therefore exist for all bundles). However, bundle-specific base field overrides can also be provided by 'base_field_override' configuration entities, and that is the recommended approach except in cases where an entity type needs to provide a bundle-specific base field override that is decoupled from configuration. Note that for most entity types, the bundles themselves are derived from configuration (e.g., 'node' bundles are managed via 'node_type' configuration entities), so decoupling bundle-specific base field overrides from configuration only makes sense for entity types that also decouple their bundles from configuration. In cases where both this function returns a bundle-specific override of a base field and a 'base_field_override' configuration entity exists, the latter takes precedence.

@todo WARNING: This method will be changed in https://www.drupal.org/node/2346347.

\Drupal\Core\Entity\EntityTypeInterface $entity_type: The entity type definition. Useful when a single class is used for multiple, possibly dynamic entity types.

string $bundle: The bundle.

\Drupal\Core\Field\FieldDefinitionInterface[] $base_field_definitions: The list of base field definitions.

Return value

\Drupal\Core\Field\FieldDefinitionInterface[] An array of bundle field definitions, keyed by field name.
