    - #### mapIterator

          MapIterator<K,V> mapIterator()

      Obtains a `MapIterator` over the map.

      A map iterator is an efficient way of iterating over maps. There is no need to access the entry set or use Map Entry objects.

           IterableMap map = new HashedMap();
           MapIterator it = map.mapIterator();
           while (it.hasNext()) {
             String key = it.next();
             Integer value = it.getValue();
             it.setValue(value + 1);
           }

      Returns:
        a map iterator
