title: ng-class with function and Expression
body: <p>I need to add two classes by using ng-class  ,one class I am getting by a function another I need to get by an expression -
  Below is code which I am using but getting some syntax error -</p>
  
  <pre><code> &lt;div class="field-icon" ng-class="getFieldClass(entry.entry_type_id) , 'used':  entry_map[entry.guid] &gt; 0" &gt;&lt;/div&gt;
  </code></pre>
  
  <p>What would be correct syntax if it is possible to use function and expression together.</p>
