Commons Collections 3 is in maintenance mode. Commons Collections 4 should be used instead.

Defines a map that can be iterated directly without needing to create an entry set.

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

  IterableMap map = new HashedMap();
  MapIterator it = map.mapIterator();
  while (it.hasNext()) {
    Object key = it.next();
    Object value = it.getValue();
    it.setValue("newValue");
  }
