public static class Object2DoubleMaps.EmptyMap<K> extends Object2DoubleFunctions.EmptyFunction<K> implements Object2DoubleMap<K>, java.io.Serializable, java.lang.Cloneable
This class may be useful to implement your own in case you subclass a type-specific map.

public ObjectSet<Object2DoubleMap.Entry<K>> object2DoubleEntrySet()
Object2DoubleMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Map.entrySet()
so that it returns an ObjectSet
of type-specific entries (the latter makes it possible to
access keys and values with type-specific methods).
