public abstract class AbstractReferenceSet<K> extends AbstractReferenceCollection<K> implements 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().

Note 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.
