Method Detail

compare

public int compare(java.lang.Object o1List,
                   java.lang.Object o2List)

Compares two rows within a TablePO data. The comparator checks to make sure that each argument is a List containing the data for each column of the row. The item at the current sortCol position within both lists are extracted and compared. Depending on the type of data extracted and the value of the sortDescending flag, the values are compared and the method returns a -1 if o1List should come after o2List, 0 if o1List and o2List are equal, and 1 if o1List should come before o2List
