I have a paginator class which should get the limit out of the config.xml and the current page from the controller.
How do I define the limit in config.xml and how can I access it outside the controller?
Regards

Define your paginator class as DIC service and add service_container as a service e.g
//paginator class
//namespace definitions
use Symfony\Component\DependencyInjection\ContainerInterface;
class Paginator{
/**
* @var Symfony\Component\DependencyInjection\ContainerInterface
*/
private $container;
public function __construct(ContainerInterface $container){
$this->container = $container;
}
public function yourPaginationMethod(){
$limit = $this->container->getParameter("limit.conf.parameter");
//rest of the method
}
}
And then in you services.yml of your bundle.
#services.yml
paginator_service:
class: FQCN\Of\Your\PaginatorClass
arguments: [@service_container]
And in your controller you can get access of the Paginator in following way.
//in controller method
$paginator = $this->get('paginator_service');
For more info about it you can check Service container section of Symfony Documentation.

Passing the entire container might not be such a good idea if you just need a parameter. You can pass the parameter itself directly to your service with %limit.conf.parameter%
