Class AbstractReferenceCollection<K>

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.

Method Detail

iterator

public abstract ObjectIterator<K> iterator()

Description copied from class: java.util.AbstractCollection

Returns an iterator over the elements contained in this collection.

Specified by:

iterator in interface ObjectIterable<K>

Specified by:

iterator in interface ReferenceCollection<K>

Specified by:

iterator in interface Iterable<K>

Specified by:

iterator in interface Collection<K>

Specified by:

iterator in class AbstractCollection<K>

Returns:

an iterator over the elements contained in this collection

See Also:

Iterable.iterator()

toString

public String toString()

Description copied from class: java.util.AbstractCollection

Returns a string representation of this collection. The string representation consists of a list of the collection's elements in the order they are returned by its iterator, enclosed in square brackets ("[]"). Adjacent elements are separated by the characters ", " (comma and space). Elements are converted to strings as by String.valueOf(Object).

Overrides:

toString in class AbstractCollection<K>

Returns:

a string representation of this collection
