This class an iterator class for objects.
Call ObjectKeyReverseIterator::next() to iterate through the object in reverse order; do not use the iterator if ObjectKeyReverseIterator::next() returns False. A object can be iterated in reverse order by calling ObjectKeyReverseIterator::prev() instead of ObjectKeyReverseIterator::next()
- Example: ObjectKeyReverseIterator basic usage
13 ObjectKeyReverseIterator it(o);
15 printf(
"iter: %n\n", it.getValue());
