Ok, it confirms what I was thinking.
But one of the goals of DI is to give flexibility and externalize (or
"invert") the class instanciations too.
So what if the end user wants to change the Paginator class ?
Should I set the class name as a DI parameter and then use it to
create my class ? example:
$class = $this->container->getParameter('ecommerce.paginator.class');
$adapterClass = $this->container-
>getParameter('ecommerce.paginator.adapter.class');
$adapter = new $adapterClass($query);
new $class($adapter);
Do you think it's a good idea?
Thanks btw,
Florian.
