I have a custom function which is called on publish, similar to this article. 

public class EventInitializationModule : IInitializableModule
    {
        public void Initialize(InitializationEngine context)
        {
            var contentEvents = ServiceLocator.Current.GetInstance();
            contentEvents.PublishingContent += PublishContent;
        }
        void PublishContent(object sender, ContentEventArgs e)
        {
            myClass c = new myClass();
            c.PublishEvent(sender, e);
        }
        public void Uninitialize(InitializationEngine context)
        {
            var contentEvents = ServiceLocator.Current.GetInstance();
            contentEvents.PublishingContent -= PublishContent;
        }
    }

When PublishContent is hit, it is being passed SaveContentEventArgs instead of the parent ContentEventArgs.

Inside myClass.PublishEvent() I want to be able to get the language of the content being published. Is this possible? All the documentation points to using ContentLanguageEventArgs but there seems to be no way to pass that type instead of SaveContentEventArgs.
