Hello Nick,
Thanks for your answer.
You should expect that a programmer has already did the casting.
Otherwise, I wouldn't have posted this message.
Shame on you if you cannot atleast assume that ;-)).

Looks like you need to cast it to the ancestor class
when you pass it. Inside your method, you can get the
functionality you're looking for by casting back down.
But as a rule, beware of extending a general utility
class: this is architectural heresy. You probably want
to do something else.
Also, shame on you for posting here. ;)
