Another approach distinguishes between Rev objects and domain objects, and creates a Rev group for each domain object, with the new group's owner being the domain object's class. A domain class has a Rev group whose owner is the superclass. Then single inheritance, with inherited scripts, is nearly free when one sends a message to any domain object's group. A new stack, according to "Get Info" on OS X, takes 4KB on disk. Adding 1000 groups makes the stack take 84KB. That's 80 bytes per domain object. On my 2GHz PowerMac, that takes 8 milliseconds per domain object. Simple, cheap, and effective, right? -- Dick _______________________________________________ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
