it.unimi.dsi.fastutil.objects.Reference2DoubleMaps.EmptyMap<K>
public static class Reference2DoubleMaps.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.

public boolean containsValue(double v)

public void putAll(Map<? extends K,? extends Double> m)
putAll
in interface Map<K,Double>
public ObjectSet<Reference2DoubleMap.Entry<K>> reference2DoubleEntrySet()
Reference2DoubleMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Reference2DoubleMap.entrySet()
so that it returns an ObjectSet
of objects of type Reference2DoubleMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
