Can You Decorate a Black Box?

I have a quick, very uninformed question about the Decorator pattern. If I have a class called BlackBox that I cannot edit in any way - can't add an interface, can't make any of the methods virtual, etc. - can this object be decorated using the Decorator pattern? If so, how?

Solution

You can create a wrapper for it (i.e., implement the Adapter pattern) and decorate the adapter.
