Method Detail

get

public K get(int i)

Specified by:

get in interface java.util.List<K>

remove

public boolean remove(java.lang.Object k)

Specified by:

remove in interface java.util.Collection<K>

Specified by:

remove in interface java.util.List<K>

Overrides:

remove in class java.util.AbstractCollection<K>

remove

public K remove(int i)

Description copied from class: AbstractReferenceList

This implementation always throws an UnsupportedOperationException.

Specified by:

remove in interface java.util.List<K>

Overrides:

remove in class AbstractReferenceList<K>

contains

public boolean contains(java.lang.Object k)

Description copied from class: AbstractReferenceList

Returns true if this list contains the specified element.

This implementation delegates to indexOf().

Specified by:

contains in interface java.util.Collection<K>

Specified by:

contains in interface java.util.List<K>

Overrides:

contains in class AbstractReferenceList<K>

See Also:

List.contains(Object)

toArray

public java.lang.Object[] toArray()

Specified by:

toArray in interface java.util.Collection<K>

Specified by:

toArray in interface java.util.List<K>

Overrides:

toArray in class java.util.AbstractCollection<K>

listIterator

public ObjectListIterator<K> listIterator()

Description copied from class: AbstractReferenceList

Returns a type-specific list iterator on the list.

This implementation delegates to listIterator(0).

Specified by:

listIterator in interface java.util.List<K>

Specified by:

listIterator in interface ReferenceList<K>

Overrides:

listIterator in class AbstractReferenceList<K>

See Also:

List.listIterator()

iterator

public ObjectListIterator<K> iterator()

Description copied from class: AbstractReferenceList

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.

This implementation delegates to AbstractReferenceList.listIterator().

Specified by:

iterator in interface java.util.Collection<K>

Specified by:

iterator in interface java.lang.Iterable<K>

Specified by:

iterator in interface java.util.List<K>

Specified by:

iterator in interface ObjectIterable<K>

Specified by:

iterator in interface ReferenceCollection<K>

Specified by:

iterator in interface ReferenceList<K>

Overrides:

iterator in class AbstractReferenceList<K>

Returns:

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

See Also:

Iterable.iterator()

listIterator

public ObjectListIterator<K> listIterator(int i)

Description copied from class: AbstractReferenceList

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

This implementation is based on the random-access methods.

Specified by:

listIterator in interface java.util.List<K>

Specified by:

listIterator in interface ReferenceList<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.

Note that this specification strengthens the one given in List.subList(int,int).

Specified by:

subList in interface java.util.List<K>

Specified by:

subList in interface ReferenceList<K>

Overrides:

subList in class AbstractReferenceList<K>

See Also:

List.subList(int,int)

addAll

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

Description copied from class: AbstractReferenceList

Adds all of the elements in the specified collection to this list (optional operation).

Specified by:

addAll in interface java.util.List<K>

Overrides:

addAll in class AbstractReferenceList<K>

addAll

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

Description copied from class: AbstractReferenceList

This implementation delegates to the type-specific version of List.addAll(int, Collection).

Specified by:

addAll in interface java.util.Collection<K>

Specified by:

addAll in interface java.util.List<K>

Overrides:

addAll in class AbstractReferenceList<K>

size in interface java.util.List<K>

Specified by:

size in class java.util.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:
