Yii: Catching all exceptions for a specific controller

Question

I am working on a project which includes a REST API component. I have a controller dedicated to handling all of the REST API calls.

Is there any way to catch all exc

I'm using the following Base controller for an API, it's not stateless API, mind you, but it can serve just aswell.

class BaseJSONController extends CController{

        public $data = array();

        public $layout;

        public function filters()
        {
                return array('mainLoop');
        }

        /**
         * it all starts here
         * @param unknown_type $filterChain
         */
        public function filterMainLoop($filterChain){
                $this->data['Success'] = true;
                $this->data['ReturnMessage'] = "";
                $this->data['ReturnCode'] = 0;
                try{
                        $filterChain->run();

                }catch (Exception $e){
                        $this->data['Success'] = false;
                        $this->data['ReturnMessage'] = $e->getMessage();
                        $this->data['ReturnCode'] = $e->getCode(); 
                }

                echo json_encode($this->data);
        }
}

You could also catch dbException and email those, as they're somewhat critical and can show underlying problem in the code/db design.
