Class PCASortColors

java.lang.Object

javanotes.PCASortColors

public class PCASortColors
extends java.lang.Object

Sort an array of colors. Client constructs data as PCASortColors.PCAColor[] (contents may be subclass of PCAColor) and passes this array to a PCAColorSort.sortByXXXX method. The result will be a reordering of the array. If the original order must be preserved, it is up to the client to make a copy before calling SortByXxxx
