如何在Laravel中向控制器添加过滤器参数？

I want to add some parameters to a filter in Laravel framework.
The catch is, that i am calling my filters from controller's constructor and not route.

My code look like this:

Controller

public function __construct()
{
    $this->filter('before','test');
}

Filter

Route::filter('test',function(){
    // echo parameters passed to filter in controller.
});

Thanks for your help!

For anyone else, it's quite simple..

Controller

$this->filter('before','test',array('value'));

Filter

Route::filter('test',function($label){
    echo $label; // Outputs the 'value'
});
