it.unimi.dsi.fastutil.doubles.Double2CharMaps.EmptyMap
public static class Double2CharMaps.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 void putAll(Map<? extends Double,? extends Character> m)
putAll
in interface Map<Double,Character>
public ObjectSet<Double2CharMap.Entry> double2CharEntrySet()
Double2CharMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Double2CharMap.entrySet()
so that it returns an ObjectSet
of objects of type Double2CharMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
