Class ValueHolder

  +--voji.utils.ValueHolder

public class ValueHolder

extends java.lang.Object

This class holds a value under a certain name. It seems to be the name Object, but it also contains the value Object. It's useful for Lists, ComboBoxes and Tables when you want the user to see "Eleven" but want to work with the result 11.
This could be also a replacement for voji.utils.choice, if it would work :-(
