I understand your position, but from my own viewpoint I would rather write a single "unmodified" FilterReader that nests another FilterReader than add negation logic to all Ant's existing built-in FilterReaders, plus place the burden on the author of any not yet written, imposing a handicap on any preexisting FilterReader implementation, etc., etc. Again, the concept of a single negation filter originated, as far as I know, with me (yes, I know it's impossible to have a truly original thought, but to the best I can tell I was the first person to suggest it in the context of Ant). It is a preference of mine to have small, reusable pieces... an echo of the Unix philosophy and probably relating to AOP as well. While my original concept of a <not> filter was shown to be impractical, <unmodified> seems a fairly easy concept to grasp. Its most complex aspect would probably be the fact that it should have the ability to use tempfiles if applied to too-large data, but this could be left as a todo (I don't think most of Ant's built-in filters deal too well with HUGE input). So... in there you can find my answer and its justification. -Matt > > > By all means, be my guest Matt ;-) --DD > > > > On 7/11/06, Matt Benson <[EMAIL PROTECTED]> > wrote: > > > --- Dominique Devienne <[EMAIL PROTECTED]> > wrote: > > > > > > > this are not conditions, but filters.
