WebReturns an iterator pointing to the first element in the unordered_map container (1) or in one of its buckets (2).

WebMultiple iterators can be used on the same map. If you add items to the map, existing iterators will remain valid. If you remove items from the map, iterators that point to the removed items will become dangling iterators. See also QMap::const_iterator and QMutableMapIterator.
