Constructor	Description
RowBasedColumnComparator(RowObjectTableModel<T> model, int sortColumn, java.util.Comparator<java.lang.Object> comparator)	Constructs this class with the given column comparator that will get called after the given row is converted to the column value for the given sort column
RowBasedColumnComparator(RowObjectTableModel<T> model, int sortColumn, java.util.Comparator<java.lang.Object> comparator, java.util.Comparator<java.lang.Object> backupRowComparator)	This version of the constructor is used for the default case where the client will supply a backup row comparator that will get called if the given column comparator returns a '0' value.
