using-caching-to-speed-up-your-code

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:

cleanCache();
?>

Assume I right that this actually should be:

clean();
?>

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