 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:

Method Detail- 
toStringpublic java.lang.String toString() Description copied from class:BaseSelectorContainerConvert 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
 
 - 
setAllowtiepublic void setAllowtie(boolean tiebreaker) A attribute to specify what will happen if number 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
 
 - 
isSelectedpublic 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.- Specified by:
- isSelectedin interface- FileSelector
- Specified by:
- isSelectedin class- BaseSelectorContainer
- Parameters:
- basedir- the base directory the scan is being done from
- filename- is the name of the file to check
- file- is a java.io.File object for the filename that the selector can use
- Returns:
- whether the file should be selected or not
