Before waiting for the "Lists aren't Sets; one is ordered and the other is not" answer to my previous reply, I should point out that the discussion around List::Compare has had methods for lists, sets, and bags.
At least the methods for sets appear to be duplications of the work in Set::Scalar. (Perhaps you're already using Set::Scalar in your implementation and I just haven't looked?) Is there a motivation for putting these methods in the same package? Why not List::Compare, Set::Compare, and Bag::Compare as seperate classes? mark --- Mark Dilger <[EMAIL PROTECTED]> wrote: > Is there significant differences in the conception > of List::Compare and the existing Set::Scalar > package? > > For instance: > > use Set::Scalar; > > my @a = getListA(); > my @b = getListB(); > > my $comp = Set::Scalar->new(@a)->compare( > Set::Scalar->new(@b) > ); > > This, of course, creates two throw-away blessed > objects, but I don't know if your proposed > solution wouldn't throw away at least a couple > of hashes after the compare anyway... > > Hope this helps, > > Mark Dilger > > --- Janek Schleicher <[EMAIL PROTECTED]> wrote: > > Terrence Brannon wrote at Thu, 27 Jun 2002 > 15:53:55 > > +0200: > > > > >> and the equivalents isnt_equal, isnt_equal_set, > > isnt_equal_bag. > > > > > > why not simply do: > > > not List::Compare->is_equal_set > > > > > > the negated methods seem unnecessary. > > > > Of course the are unnecessary. > > Well, but from a linguistic view, > > it seem's reasonable. > > > > If there are two things different, the english > > speaker says, > > that "compared, they aren't equal". > > > > I think it's the same principle like with the > > statements 'if' and 'unless'. > > One of the both is unnecessary, but I won't miss > > anyone. > > > > However, from a linguistic view, > > the methods a suggested should be called better: > > > > are_equal, are_equal_sets, are_equal_bags > > (perhaps shorter as are_eq, are_eq_sets, > > are_eq_bags) > > and the negative methods: > > arent_eq, arent_eq_sets, arent_eq_bags. > > (perhaps are_diff, are_diff_sets and are_diff_bags > > is a better name) > > > > > > Greetings, > > Janek > > > > > __________________________________________________ > Do You Yahoo!? > Yahoo! - Official partner of 2002 FIFA World Cup > http://fifaworldcup.yahoo.com __________________________________________________ Do You Yahoo!?
