CakePHP: $this->Auth->allow() and $this->Auth->allowedActions() - when do I use them?

Question

What is the difference between using the method

$this->Auth->allow()

and setting the variable

$this->Auth->allowedActions ?

I can't find any information about setting the allowedActions array where I expected to find it (http://book.cakephp.org/view/1251/Setting-Auth-Component-Variables) - but it exists in the API at http://api13.cakephp.org/class/auth-component.

Can someone please explain which different circumstances I should use them?
