    • mapIterator

      public MapIterator<K,V> mapIterator()
      Description copied from interface: IterableGet
      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

    • put

      public V put(K key, V value)
      Description copied from interface: Put
      Associates the specified value with the specified key in this map.

      Note that the return type is Object, rather than V as in the Map interface. See the class Javadoc for further info.

      Specified by:
      put in interface Map<K,V>
      Specified by:
      put in interface Put<K,V>
      Parameters:
      key - key with which the specified value is to be associated
      value - value to be associated with the specified key
      Returns:
      the previous value associated with key, or null if there was no mapping for key. (A null return can also indicate that the map previously associated null with key, if the implementation supports null values.)

    • putAll

      public void putAll(Map<? extends K,? extends V> t)
      Description copied from interface: Put
      Copies all of the mappings from the specified map to this map.
      Specified by:
      putAll in interface Map<K,V>
      Specified by:
      putAll in interface Put<K,V>
      Parameters:

      Specified by:
      remove in interface Map<K,V>
      Parameters:
      key - key whose mapping is to be removed from the map
      Returns:
      the previous value associated with key, or null if there was no mapping for key.
