I want to override method ajaxAddArticleCartAction in engine/Shopware/Controllers/Frontend/Checkout.php, cuz i want a bit complicated logic on accessories quantity calculation.
My question is: Is it possible to override this method in my custom plugin. With other words, if i add product in cart, i want to use my function (in plugin), not the Shopware one.
Thanks a lot!

Yes that is possible. You can use an event hook through which you can either execute something before, after or instead of a given action in any controller.
