public class OrderedMergerEnumeration

implements Enumeration

Represents enumeration which built from two others. This enumeration contains ordered merge from first and second source enumerations. For example: first={1,3,5}, second={2,4,6}, result={1,2,3,4,5,6}. For comparing used class which has to implement java.util.Comparator interface.
