title: what is the actual type of object parameter in vote method of spring security access decision voter
body: <p>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 </p>
  
  <pre><code>public int vote(Authentication authentication, Object o, Collection&lt;ConfigAttribute&gt; configAttributes) { 
  </code></pre>
  
  <p>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?</p>
  
  <p>Thanks in advance.</p>
