it.unimi.dsi.fastutil.objects.Reference2ByteMaps.EmptyMap<K>
public static class Reference2ByteMaps.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(byte v)

public void putAll(Map<? extends K,? extends Byte> m)
putAll
in interface Map<K,Byte>
public ObjectSet<Reference2ByteMap.Entry<K>> reference2ByteEntrySet()
Reference2ByteMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Reference2ByteMap.entrySet()
so that it returns an ObjectSet
of objects of type Reference2ByteMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
