Class with only methods - less memory? Thank You

[sunburned.surveyor]

I want to thank all of the developers that responded to my post below
about a class with only method definitions.

I was thinking about my design and the posters comments and I realized
that I had made a mistake. My class will contain a single member
variable. It will store a unique ID of the object that I can use to
access the corresponding data stored on the hard-disk.

Thanks for helping me figure this one out.
