If you are talking of the space for the object header I don't think that is significant, given all the space u r using for date objects anyway.
In any case, you can always use a struct if u r concerned about space overhead (though I don't think that is the issue here). If you want to have a mutable field f of type T use one level of indirection and have an immutable field f of type Cell[T], e.g.: val value: Cell[Int] now instead of writing d.value = 35; to mutate the field, you would write d.value() = 35; Hope this helps, Vijay ------------------------------------------------------------------------------ Comprehensive Server Monitoring with Site24x7.
