Class MajoritySelector
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).
Since: 1.5
