what is the actual type of object parameter in vote method of spring security access decision voter
===

I am currently working on a simple role based access control in Spring. I am using an implementation of AccessDecisionVoter. So i wonder what is the Object o parameter in the 

    public int vote(Authentication authentication, Object o, Collection<ConfigAttribute> configAttributes) { 

method? Spring documentation says it is "the secured object". I use intercept-urls and this voter gets called, so is it a controller? Or is it just a string of the url?

Thanks in advance.
