Using Caching to Speed Up Your Code

From Joomla! Documentation

Hi, I just started to familiarize myself with Joomla's caching, but I came accross en error with the following piece of code:

While testing the code we can use the following method to clean the cache:

<?php
$cache->cleanCache();
?>

Assume I right that this actually should be:

<?php
$cache->clean();
?>

I hope I am right as this is my first contribution to Joomla Docs ;-)
