| * class are used instead of the regular ones obtained by |
| * {@link Map#entrySet()}, then we need not worry about the actual field-names |
| * or any changes to them in the future.<BR> |
| * Example: {@code ConcurrentHashMap.MapEntry} does not name the fields as key/ |
| * value in Java 1.8 while it used to do so in Java 1.7 |

| * @param <V> Value of the map-entry |
