There is a considerable ammount of data that is stored in the vbulletin class, you can learn more about it by going though the class_ and dm_ files in the includes folder. I believe you may also be able to print the entire array but I'm not 100% positive.
I don't think you can print out a class...

It holds userinfo and other little variables and links to classes, like $db...
