PHP ConfigEntityInterface::getDependencies方法代码示例

 /**
  * Calls an entity's onDependencyRemoval() method.
  *
  * A helper method to call onDependencyRemoval() with the correct list of
  * affected entities. This list should only contain dependencies on the
  * entity. Configuration and content entity dependencies will be converted
  * into entity objects.
  *
  * @param \Drupal\Core\Config\Entity\ConfigEntityInterface $entity
  *   The entity to call onDependencyRemoval() on.
  * @param \Drupal\Core\Config\Entity\ConfigEntityInterface[] $dependent_entities
  *   The list of dependent configuration entities.
  * @param string $type
  *   The type of dependency being checked. Either 'module', 'theme', 'config'
  *   or 'content'.
  * @param array $names
  *   The specific names to check. If $type equals 'module' or 'theme' then it
  *   should be a list of module names or theme names. In the case of 'config'
  *   or 'content' it should be a list of configuration dependency names.
  *
  * @return bool
  *   TRUE if the entity has changed as a result of calling the
  *   onDependencyRemoval() method, FALSE if not.
