it.unimi.dsi.fastutil.chars.Char2LongMaps.EmptyMap
public static class Char2LongMaps.EmptyMap
An immutable class representing an empty type-specific map.
This class may be useful to implement your own in case you subclass a type-specific map.

public boolean containsValue(long v)

public ObjectSet<Char2LongMap.Entry> char2LongEntrySet()
Char2LongMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Char2LongMap.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).
