Java doc that only shows public entries does indeed not
help, since the magic happens in a package local method.

 From HashMap:

     // Subclass overrides these to alter behavior of views' iterator() 
method
     Iterator<K> newKeyIterator()   {
         return new KeyIterator();
     }
     Iterator<V> newValueIterator()   {
         return new ValueIterator();
     }
     Iterator<Map.Entry<K,V>> newEntryIterator()   {
         return new EntryIterator();
     }

 From LinkedHashMap:

     // These Overrides alter the behavior of superclass view iterator() 
methods
     Iterator<K> newKeyIterator()   { return new KeyIterator();   }
     Iterator<V> newValueIterator() { return new ValueIterator(); }
     Iterator<Map.Entry<K,V>> newEntryIterator() { return new 
EntryIterator(); }
