it.unimi.dsi.fastutil.doubles.Double2ByteMaps.EmptyMap
public static class Double2ByteMaps.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 ObjectSet<Double2ByteMap.Entry> double2ByteEntrySet()
Double2ByteMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Double2ByteMap.entrySet()
so that it returns an ObjectSet
of objects of type Double2ByteMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
