I'm not sure if this is the context where you want some explanation about a wrapper class, but here it goes:

Imagine that you have a method that must return two values, or an object and a value. What do you do? well, create a wrapper class to grab the value and the object and return that class (but some questions arise: aren't your method trying to do more than it should? make sense, in terms of OO create such a class?)

hope it helps,
