com.jalios.util.DateDescendingComparator<T>

Type Parameters:

All Implemented Interfaces:

java.util.Comparator<T>

public class DateDescendingComparator<T extends java.util.Date>
extends DateComparator<T>

This class implements a Comparator which compares two Date objects in the descending order. It is the reverse comparator of DateComparator. Note: because it's a descending comparator, it behaves in the opposite way of what Comparator says.
