public function EntityTypeRepository::getEntityTypeFromClass

public EntityTypeRepository::getEntityTypeFromClass($class_name)

Parameters

Return value

string The entity type ID.

Throws

\Drupal\Core\Entity\Exception\AmbiguousEntityClassException Thrown when multiple subclasses correspond to the called class.
