public static class Long2ObjectMaps.Singleton<V> extends Long2ObjectFunctions.Singleton<V> implements Long2ObjectMap<V>, Serializable, Cloneable
An immutable class representing a type-specific singleton map.
This class may be useful to implement your own in case you subclass a type-specific map.

long2ObjectEntrySet
Description copied from interface:Long2ObjectMap
Returns a type-specific set view of the mappings contained in this map.This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen
Map.entrySet()
so that it returns anObjectSet
of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).- Specified by:
long2ObjectEntrySet
in interfaceLong2ObjectMap<V>
- Returns:
- a type-specific set view of the mappings contained in this map.
