No problem with this method.

I would suggest to have the setOrder(Object [] contents), because I 
think that usually clients have the array of objects from the collection 
somehow sorted and don't want to compute permutation to be able to force 
collection to remember new order. Or maybe both methods could be available.

This is interesting, once we add changes notifications anywhere people 
start to request atomic operations (better with events coalescing).
