I concur with Clark. What he's proposing is (it seems to me) nothing more than a "read-only" flag, and that's as immutable as a variable needs to get. However, I'm concerned about the performance impact of such a thing. Perhaps a better approach would be to swap out the mutator methods with code that throws. -- John Douglas Porter __________________________________________________ Do You Yahoo!?
