    `V` - the type of the values in this map
  All Implemented Interfaces:
    Map<K,V>, Get<K,V>, IterableGet<K,V>, IterableMap<K,V>, Put<K,V>
  Direct Known Subclasses:
    AbstractMapDecorator, CompositeMap, StaticBucketMap

      public abstract class AbstractIterableMap<K,V>
      extends Object
      implements IterableMap<K,V>

          public AbstractIterableMap()

  - ### Method Detail

    - #### mapIterator

          public 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);
           }

      Specified by:
        `mapIterator` in interface `IterableGet<K,V>`
      Returns:
        a map iterator
