Sort threaded list in MVC pattern design [closed]

In my project I'm using a threaded implementation of my own list, that is, I'm not using the Java API ready list. Also, my implementation is from a generic list, which has objects of type Object on their nodes, so that it can be used for any type of Object. I need to sort this list chained to a given attribute of a specific type of object. In the MVC standard, which one wanted the ideal place for this ordering? I thought about doing the sorting in the threaded list itself, but that would "break" the generality of it, because the sorting I want is only for a specific type of object.
