reverse iterator class for QoreHashNode, to be only created on the stack
| DLLEXPORT bool ReverseHashIterator::next | ( | ) |
moves to the next element in reverse order, returns false when there are no more elements to iterate
also moves to the last element if the object has just been initialized after a complete iteration (assuming there is at least one element in the hash)
| DLLEXPORT bool ReverseHashIterator::prev | ( | ) |
moves to the previous element in reverse order, returns false when there are no more elements to iterate
also moves to the first element if the object has just been initialized after a complete iteration (assuming there is at least one element in the hash)
