MajoritySelector (Apache Ant API)
Class MajoritySelector










All Implemented Interfaces:
FileSelector, SelectorContainer

public class MajoritySelector
extends BaseSelectorContainer

This selector is here just to shake up your thinking a bit. Don't get too caught up in boolean, there are other ways you can evaluate a collection of selectors. This one takes a vote of the selectors it contains, and majority wins. You could also have an "all-but-one" selector, a "weighted-average" selector, and so on. These are left as exercises for the reader (as are the usecases where this would be necessary).
