function hook_entity_bundle_field_info

hook_entity_bundle_field_info(\Drupal\Core\Entity\EntityTypeInterface $entity_type, $bundle, array $base_field_definitions)

Provides field definitions for a specific bundle within an entity type.

Bundle fields either have to override an existing base field, or need to provide a field storage definition via hook_entity_field_storage_info() unless they are computed.

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

Parameters

\Drupal\Core\Entity\EntityTypeInterface $entity_type: The entity type definition.

string $bundle: The bundle.

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

Return value

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