Method Detail

compare

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

Compares two selection list choices. The comparator checks to make sure that each argument is a java.lang.Object[] containing the value/label data for the selection choice. The item at the current useIndex position within both arrays 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
