AbstractReferenceCollection (fastutil 8.2.3)

java.lang.Object
- 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.

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 class AbstractCollection<K>
    
    Returns:
    
    a type-specific iterator on the elements of this collection.
