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

    Returns:
      a map iterator
