## org.apache.tools.ant.types.selectors
Class MajoritySelector

    java.lang.Object
      org.apache.tools.ant.ProjectComponent
          org.apache.tools.ant.types.DataType
              org.apache.tools.ant.types.selectors.BaseSelector
                  org.apache.tools.ant.types.selectors.BaseSelectorContainer
                      org.apache.tools.ant.types.selectors.MajoritySelector

All Implemented Interfaces:
  java.lang.Cloneable, 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).

Since:
  1.5

Constructor Detail

### MajoritySelector

    public MajoritySelector()

  Default constructor.

Method Detail

### 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:
    `toString` in class `BaseSelectorContainer`
  Returns:
    a string describing this object

### setAllowtie

    public 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

### 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.

  Specified by:
    `isSelected` in interface `FileSelector`
  Specified by:
    `isSelected` in 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
