java.lang.Object
  zinger.bsheet.BSHTableModelComparable

All Implemented Interfaces:

java.lang.Comparable

public class BSHTableModelComparable
extends java.lang.Object
implements java.lang.Comparable

Data row wrapper used for sorting. Sorting BSHTableModel data works by storing raw data in the wrapper objects and then comparing evaluated values. Comparisons are made in the order of columns provided using custom comparators, if present.
