public abstract class AbstractReferenceSet<K> extends AbstractReferenceCollection<K> implements java.lang.Cloneable, ReferenceSet<K>
Warning: As in the case of a type-specific abstract collection,
the type-specific deletion method of a type-specific abstract
set is rem(), rather then remove(). A
subclass must thus override rem(), rather than
remove(), to make all inherited methods work properly.
Note, however, that this class specifies a type-specific remove()
that just invokes rem(), so final users of the class do not
need to know about rem().

ReferenceCollectionNote that this specification strengthens the one given in
Iterable.iterator(), which was already
strengthened in the corresponding type-specific class,
but was weakened by the fact that this interface extends Collection.
