Get the user language in the back office

Hi everybody,

I am currently developping a dashboard module. I was wondering if there were a simple way to get the language that the user selected in his profile. I've found this : 

Configuration::get('PS_LANG_DEFAULT');

but it just return the id of the language. Is there a built-in method that does it ?

This works fine : 

$this->context->language->iso_code;
