public abstract class AbstractReferenceCollection<K> extends AbstractCollection<K> implements ReferenceCollection<K>
An abstract class providing basic methods for collections implementing a type-specific interface.In particular, this class provide
iterator()
,add()
,AbstractCollection.remove(Object)
andAbstractCollection.contains(Object)
methods that just call the type-specific counterpart.Warning: Because of a name clash between the list and collection interfaces the type-specific deletion method of a type-specific abstract collection is
rem()
, rather thenremove()
. A subclass must thus overriderem()
, rather thanremove()
, to make all inherited methods work properly.

iterator
public abstract ObjectIterator<K> iterator()
Description copied from interface:ReferenceCollection
Returns a type-specific iterator on the elements of this collection.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 extendsCollection
