Class AbstractReferenceCollection<K>

java.util.AbstractCollection<K>

it.unimi.dsi.fastutil.objects.AbstractReferenceCollection<K>

All Implemented Interfaces:

ObjectIterable<K>, ReferenceCollection<K>, Iterable<K>, Collection<K>

Direct Known Subclasses:

AbstractReferenceBigList, AbstractReferenceList, AbstractReferenceSet, ReferenceCollections.EmptyCollection, ReferenceCollections.IterableCollection

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) and AbstractCollection.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 then remove(). A subclass must thus override rem(), rather than remove(), to make all inherited methods work properly.

Method Details

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 extends Collection.

Specified by:

iterator in interface Collection<K>

Specified by:

iterator in interface Iterable<K>

Specified by:

iterator in interface ObjectIterable<K>

Specified by:

iterator in interface ReferenceCollection<K>

Specified by:

iterator in class AbstractCollection<K>

Returns:

a type-specific iterator on the elements of this collection.
