doCompare method
- covariant OrdinalSortKey other
override
The implementation of compareTo.
The argument is guaranteed to be of the same type as this object and have the same name.
The method should return a negative number if this object comes earlier in the sort order than the argument; and a positive number if it comes later in the sort order. Returning zero causes the system to use default sort order.
Implementation
@override
int doCompare(OrdinalSortKey other) {
if (other.order == order) {
return 0;
}
return order.compareTo(other.order);
}
