public static class ReferenceSets.EmptySet<K>
- extends ReferenceCollections.EmptyCollection<K>
- implements ReferenceSet<K>, Serializable, Cloneable
An immutable class representing the empty set and implementing a type-specific set interface.
This class may be useful to implement your own in case you subclass
a type-specific set.

- Description copied from interface:
ReferenceSet
- Removes an element from this set.
Note that the corresponding method of the type-specific collection is rem()
.
This unfortunate situation is caused by the clash
with the similarly named index-based method in the List
interface.
