public class SortAscendingVectors
extends java.lang.Object

This class sorts one or more arrays, based on sorting a key array, ie where the corresponding entries are related. The result is that the first array is sorted in ascending order, and the second is transformed in a way that the corresponding entries are in the correct places. This class replaces SortAscending*Vectors.
