Re: Delta



Responding to Karl.wettin...

Is there a de facto way to calculate the delta between two class
instance trees? I was thinking introspection, hoping there is some
project out there (I'm on Java) but can't find anything. I need it for
persistence update transactions (in Prevayler).

Could you clarify what you mean by "instance tree"? Classes have instance sets, not instance trees. Do you mean the differences between specialization properties among subclasses of a particular superclass in a generalization? If so, I'm confused because that delta seems like a class issue rather than an instance issue. Or are you referring to run-time issues (object vs. instance)?

There is nothing wrong with me that could
not be cured by a capful of Drano.
