it.unimi.dsi.fastutil.shorts.Short2ObjectFunctions.EmptyFunction<V>
it.unimi.dsi.fastutil.shorts.Short2ObjectMaps.EmptyMap<V>
public static class Short2ObjectMaps.EmptyMap<V>
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(java.lang.Object v)
containsValue
in interface java.util.Map<java.lang.Short,V>
public void putAll(java.util.Map<? extends java.lang.Short,? extends V> m)
putAll
in interface java.util.Map<java.lang.Short,V>
public ObjectSet<Short2ObjectMap.Entry<V>> short2ObjectEntrySet()
Short2ObjectMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Short2ObjectMap.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).
