Method Detail

get

public K get(int i)

Specified by:

get in interface List<K>

remove

public K remove(int i)

Specified by:

remove in interface List<K>

Overrides:

remove in class AbstractReferenceList<K>

contains

public boolean contains(Object k)

Specified by:

contains in interface Collection<K>

Specified by:

contains in interface List<K>

Overrides:

contains in class AbstractReferenceList<K>

addAll

public boolean addAll(Collection<? extends K> c)

Description copied from class: AbstractReferenceList

Delegates to a more generic method.

Specified by:

addAll in interface Collection<K>

Specified by:

addAll in interface List<K>

Overrides:

addAll in class AbstractReferenceList<K>

Parameters:

c - a collection.

Returns:

true if this collection changed as a result of the call.

addAll

public boolean addAll(int i,
                      Collection<? extends K> c)

Specified by:

addAll in interface List<K>

Overrides:

addAll in class AbstractReferenceList<K>

removeAll

public boolean removeAll(Collection<?> c)

Description copied from class: AbstractReferenceCollection

Remove from this collection all elements in the given collection. If the collection is an instance of this class, it uses faster iterators.

Specified by:

removeAll in interface Collection<K>

Specified by:

removeAll in interface List<K>

Overrides:

removeAll in class AbstractReferenceCollection<K>

Parameters:

c - a collection.

Returns:

true if this collection changed as a result of the call.

retainAll

public boolean retainAll(Collection<?> c)

Description copied from class: AbstractReferenceCollection

Retains in this collection only elements from the given collection.

Specified by:

retainAll in interface Collection<K>

Specified by:

retainAll in interface List<K>

Overrides:

retainAll in class AbstractReferenceCollection<K>

Parameters:

c - a collection.

Returns:

true if this collection changed as a result of the call.

toArray

public Object[] toArray()

Specified by:

toArray in interface Collection<K>

Specified by:

toArray in interface List<K>

Overrides:

toArray in class AbstractReferenceCollection<K>

listIterator

public ObjectListIterator<K> listIterator()

Description copied from interface: ReferenceList

Returns a type-specific list iterator on the list.

Specified by:

listIterator in interface ReferenceList<K>

Specified by:

listIterator in interface List<K>

Overrides:

listIterator in class AbstractReferenceList<K>

See Also:

List.listIterator()

iterator

public ObjectListIterator<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 ObjectIterable<K>

Specified by:

iterator in interface ReferenceCollection<K>

Specified by:

iterator in interface ReferenceList<K>

Specified by:

iterator in interface Iterable<K>

Specified by:

iterator in interface Collection<K>

Specified by:

iterator in interface List<K>

Overrides:

iterator in class AbstractReferenceList<K>

Returns:

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

listIterator

public ObjectListIterator<K> listIterator(int i)

Description copied from interface: ReferenceList

Returns a type-specific list iterator on the list starting at a given index.

Specified by:

listIterator in interface ReferenceList<K>

Specified by:

listIterator in interface List<K>

Overrides:

listIterator in class AbstractReferenceList<K>

See Also:

List.listIterator(int)

subList

public ReferenceList<K> subList(int from,
                                int to)

Description copied from interface: ReferenceList

Returns a type-specific view of the portion of this list from the index from, inclusive, to the index to, exclusive.

Specified by:

subList in interface ReferenceList<K>

Specified by:

subList in interface List<K>

Overrides:

subList in class AbstractReferenceList<K>

See Also:

List.subList(int,int)

size

Specified by:

size in interface Collection<K>

Specified by:

size in interface List<K>

Specified by:

size in class AbstractCollection<K>

size

public void size(int size)

Description copied from interface: ReferenceList

Sets the size of this list.

If the specified size is smaller than the current size, the last elements are discarded. Otherwise, they are filled with 0/null/false.

Specified by:

size in interface ReferenceList<K>

Overrides:

size in class AbstractReferenceList<K>

Parameters:

size - the new size.

clear

public void clear()

Specified by:

clear in interface Collection<K>

Specified by:

clear in interface List<K>

Overrides:

clear in class AbstractCollection<K>

clone

public Object clone()

Overrides:
