public static class Char2CharMaps.EmptyMap extends Char2CharFunctions.EmptyFunction implements Char2CharMap, Serializable, Cloneable
This class may be useful to implement your own in case you subclass a type-specific map.

Char2CharMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Char2CharMap.entrySet()
so that it returns an ObjectSet
of objects of type Map.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
