public static class Char2ReferenceMaps.EmptyMap<V> extends Char2ReferenceFunctions.EmptyFunction<V> implements Char2ReferenceMap<V>, java.io.Serializable, java.lang.Cloneable
This class may be useful to implement your own in case you subclass a type-specific map.

public ObjectSet<Char2ReferenceMap.Entry<V>> char2ReferenceEntrySet()
Char2ReferenceMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Map.entrySet()
so that it returns an ObjectSet
of type-specific entries (the latter makes it possible to
access keys and values with type-specific methods).
