Here's a pretty nifty trick for using closure's with Jakarta Commons CollectionUtils:
List list = new ArrayList();
...
CollectionUtils.forAllDo(list, new Closure() { public void execute(Object obj) {
// execute something for each item obj
}
});
I wonder if there's any performance hit from doing things this way vs. a good ol' Iterator? Hat tip to Anand Subramanian.
