function dynamic_entity_reference_entity_bundle_delete in Dynamic Entity Reference 8

Same name and namespace in other branches

1. 8.2 dynamic_entity_reference.module \dynamic_entity_reference_entity_bundle_delete()

Implements hook_entity_bundle_delete().

We are duplicating the work done by \Drupal\dynamic_entity_reference\Plugin\Field\FieldType\DynamicEntityReferenceItem::onDependencyRemoval() because we need to take into account bundles that are not provided by a config entity type so they are not part of the config dependencies.

File

./dynamic_entity_reference.module, line 21

Contains main module functionality.
