public abstract class AbstractReferenceCollection<K> extends AbstractCollection<K> implements ReferenceCollection<K>
In particular, this class provide iterator()
, add()
, AbstractCollection.remove(Object)
and
AbstractCollection.contains(Object)
methods that just call the type-specific counterpart.

strengthened in the corresponding type-specific class,
but was weakened by the fact that this interface extends Collection
.
