[xwiki-devs] Is it possible to make a Comparator that compares XWiki objects by its properties?

I want to make such a Comparator so that I can sort objects retrieved by $xwiki.getObjects("Class") If I had the Comparator, I'd be able to pass it to a collection sort method and sort objects. I'm planning to make that Comparator in a groovy snippet. I may be able to make a Component for that even. Is it possible? If it was possible, would you give me some hints?
