it.unimi.dsi.fastutil.objects.Reference2BooleanFunctions.EmptyFunction<K>
it.unimi.dsi.fastutil.objects.Reference2BooleanMaps.EmptyMap<K>
public static class Reference2BooleanMaps.EmptyMap<K>
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.

putAll

public ObjectSet<Reference2BooleanMap.Entry<K>> reference2BooleanEntrySet()
Reference2BooleanMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Reference2BooleanMap.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).
