- 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).

MajoritySelector
public MajoritySelector()
- Default constructor.
 
toString
public java.lang.String toString()
- Description copied from class: BaseSelectorContainer
- Convert the Selectors within this container to a string. This will
 just be a helper class for the subclasses that put their own name
 around the contents listed here.
 
- 
- Overrides:
- toStringin class- BaseSelectorContainer
 
- 
- Returns:
- a string describing this object
 
setAllowtie
public void setAllowtie(boolean tiebreaker)

 of yes votes is the same as the number of no votes
 defaults to true

- Parameters:
- tiebreaker- the value to give if there is a tie
 
isSelected
public boolean isSelected(java.io.File basedir,
                          java.lang.String filename,
                          java.io.File file)
- Returns true (the file is selected) if most of the other selectors
 agree. In case of a tie, go by the allowtie setting. That defaults
 to true, meaning in case of a tie, the file is selected.
