Hi all, I've been thinking lately that I'd like to try out collection-style closures in Java, albeit as best as we can do with inner-classes. What I'd like to end up is generic versions of Map & List that are exactly the same, but * also* have methods like list.forEach(...), list.filter(....), list.anySatisfy(....) where the ... is a inner class that extends an interface or abstract class which the list or map knows how do iterate over and do the semantically meaningfull thing with.
Basically I want to be able to work with collections without having to write for( : ) loops, while( ) loops or even look at Iterators, I want to be able to write predicates that the list is smart enough to work with, but still have all the normal list & map functions available without too many helper objects or static calls around. My question is, before I go spending time I don't have on writing my own, does anyone know of a good collection API(s) in Java that already does this? I've had a poke around and found this guy with a pimped foreach loop<http://www.iam.unibe.ch/%7Eakuhn/blog/2008/pimp-my-foreach-loop/>, but I don't like his syntax because he still uses an explicit loop, not to mention the magic static calls. I also had a quick poke around in apache commons-collections (we're currently using 2.1.1 and the closure interface there looks a bit lonely, 3.2 seems to have lots more goodness but from what I've seen the syntax there is very closure-y, but not quite what I'm looking for from what I've seen ) and the Google Collections API doesn't seem to have much closure-y goodness either. any ideas anyone? Should I just write it myself or try to work with commons-collections? cheers! matt. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "The Java Posse" group.
