Class DRValueConverter

java.lang.Object
  er.grouping.DRValueConverter

public class DRValueConverter
extends java.lang.Object

Converts values. The main reason for this class is to provide a point where you can patch into the internals of the grouping framework without needing to override many classes. You'd set an instance of your subclass if you want to deal with simple Timestamps, Dates or the like.
