While I'm at it, I should mention that I store my object state in a
very specific way:
'this' contains immutable constants (even though CF doesn't have such a concept)
'variables' contains ethereal state (like caches)
'variables.my' contains "real" state
'variables.instance' seems to be a more common name for
'variables.my', but I got into the habit of calling instance variables
"my" long ago (before I started doing CF), and the convention has
stuck.
Creating a memento for such an object is as simple as duplicating the
'variables.my' struct. That's not opaque, of course, but it is an
encapsulated representation of the object's state, which is really
what you're looking for. If you want it to be opaque, you could
serialize it and encrypt it, but if you ask me, that's way overkill.
cheers,
