Problem with Generics
I've read the Sun article on Generics and I still can't get the syntax right to get rid of the " unchecked call to compare(T,T) as a member of the raw type java.util.Comparator" warning from my Java 5 compile of the standard TableSorter thanks to this snippet:
privateclass Rowimplements Comparable{
privateint modelIndex;
public Row(int index){
this.modelIndex = index;
}
publicint compareTo(Object o){
int row1 = modelIndex;
int row2 = ((Row) o).modelIndex;
for (Iterator it = sortingColumns.iterator(); it.hasNext();){
Directive directive = (Directive) it.next();
int column = directive.column;
Object o1 = tableModel.getValueAt(row1, column);
Object o2 = tableModel.getValueAt(row2, column);
int comparison = 0;
// Define null less than everything, except null.
if (o1 ==null && o2 ==null){
comparison = 0;
}elseif (o1 ==null){
comparison = -1;
}elseif (o2 ==null){
comparison = 1;
}else{
comparison = getComparator(column).compare(o1, o2);]
}
if (comparison != 0){
return directive.direction == DESCENDING ? -comparison : comparison;
}
}
return 0;
}
