not backward, just a bit circular :) > How can a sandbox component gather users without a > release? that's why it's traditionally been tough for a component to progress from the sandbox to proper. one reason for requiring a community is that the core commons committers only have so many cycles so there's a resistance to taking on components which may be self-sustaining. another is that apache is interested in community development. so, it's really developers (rather than users) that are most important for sandbox components. > There is a lot of functor-related activity out there: > > Functor Objects (Wiki) > > http://c2.com/cgi/wiki?FunctorObject > > Blocks In Java (Wiki) > > http://c2.com/cgi/wiki?BlocksInJava > > jga - Generic Algorithms for Java > > http://jga.sourceforge.net > > Colt Project > > http://dsd.lbl.gov/~hoschek/colt > > More functor interfaces > > http://www.dishevelled.org/functor yep :) the question is whether there's enough enthusiasm out there now to sustain a commons generic functor component... - robert --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
