<?php

        // cache the count value.
        // The reason it is cached is because the Paginator is actually calling the method twice.
        // An inconsistent value could be returned if between the first call and the second one, a new visit is created.
        // However, it's almost instant, and then the adapter instance is discarded immediately after.
