- about the error condition: I think it makes sense to start a new object instance with a clean error record. I am not sure though - either way is fine with me.
Maybe we should not call this "copy"? What would be the meaning (the reason for) this copy? Create a clone? Or a facsimile???
Clone in the sense of deep-copy would make sense.
Is there a word from pattern-speak describing this??
- about the callbacks: callbacks have a simple way to avoid getting called twice (they get removed on returning false). By copying the cb's to the new instance, that mechanism is effectively disabled (the cb can be called on both instances, hence twice). Also, a cb is a application level object, so the SAGA implementor has no control whatsoever on how large that object is, and copying can be very expensive.
In this case, that would make sense NOT copying it.
Hmm, right, that is what we say :-)
However, we need a cross ref to the section on callbacks, then.
BTW: Looks like we need a whole lot of cross refs all over the place???
Yes, probably. A.
Cheers,
Thilo
