Yes, exactly. This would be the no-op that I was referring to. -matthew ----- Original Message ---- From: Michael Bouschen To: Cc: Sent: Friday, March 7, 2008 1:14:51 PM Subject: Re: JDO 2.1 review: recursion-depth Hi Matthew, Yes, I remember that now. I also remember never quite understanding why 0 is an invalid value. It seems to me that 0 would result in a no-op as far as recursion goes. Why is that an error? It might be dumb, but I don't think it has to be an error. Just for my understanding: you propose a recursion-depth of 0 means the corresponding field is notfetched at all, correct? This would mean it is treated as if the fieldwas not included in the fetch-group.

Values -1 and 1 are discussed, but the subsequent example uses a value of zero, which is special enough a value to be called out explicitly. Well I'd just fix the example :-). A value of 0 is invalid isn't it? -1 is unlimited, and a positive integer is a finite number of levels. That's all we can have. I think 0 used to represent infinite levels some time back but was changed to -1 see item 22 in the Changelog -- Tech@Spree Engineering GmbH Tel.: +49/(0)30/235 520-33 Buelowstr. 66 Fax.: +49/(0)30/217 520-12 10783 Berlin Geschaeftsfuehrung: Martin Weber Sitz Berlin, Amtsgericht Charlottenburg, HRB 564 52
