Customized routing

I don't know your customization, but the current Routing behavior is:

I did this:

PHP Code:

class RouteCollection extends BaseRouteCollection
{
    public function __construct()
    {
        parent::__construct();

        $this->get('my-custom-route', [App\Controllers\MyController, 'index'])
    }
} 


Will this route be called before the routes in Routes.php?
