Where is the count query? (no criticism, I'd like to learn the structures)

I see that QueryResult::count() either uses a count() of the data if the 
dataset is already fetched, or calls 
$this->persistenceManager->getObjectCountByQuery($this->query);

PersistenceManager::getObjectCountByQuery() calls
$this->backend->getObjectCountByQuery($query);

Backend::getObjectCountByQuery() results in:
return count($this->getObjectDataByQuery($query));
