Delegates to a more generic method.

Specified by:

addAll in interface Collection<K>

Overrides:

addAll in class AbstractReferenceBigList<K>

Parameters:

c - a collection.

Returns:

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

addAll

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

Overrides:

addAll in class AbstractReferenceBigList<K>

Parameters:

i - index at which to insert the first element from the specified collection.

c - collection containing elements to be added to this big list.

Returns:

true if this big list changed as a result of the call

See Also:

List.addAll(int, Collection)

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>

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>

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>

Overrides:

toArray in class AbstractReferenceCollection<K>

listIterator

public ObjectBigListIterator<K> listIterator()

Description copied from interface: ReferenceBigList

Specified by:

listIterator in interface BigList<K>

Specified by:

listIterator in interface ReferenceBigList<K>

Overrides:

listIterator in class AbstractReferenceBigList<K>

Returns:

a big-list iterator over the elements in this big list.

See Also:

List.listIterator()

iterator

public ObjectBigListIterator<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 ReferenceBigList<K>

Specified by:

iterator in interface ReferenceCollection<K>

Specified by:

iterator in interface Iterable<K>

Specified by:

iterator in interface Collection<K>

Overrides:

iterator in class AbstractReferenceBigList<K>

Returns:

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

See Also:

List.iterator()

listIterator

public ObjectBigListIterator<K> listIterator(long i)

Description copied from interface: ReferenceBigList

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

Specified by:

listIterator in interface BigList<K>

Specified by:

listIterator in interface ReferenceBigList<K>

Overrides:

listIterator in class AbstractReferenceBigList<K>

Parameters:

i - index of first element to be returned from the big-list iterator.

Returns:

a big-list iterator of the elements in this big list, starting at the specified position in this big list.

Note that this specification strengthens the one given in BigList.subList(long,long).

Specified by:

subList in interface BigList<K>

Specified by:

subList in interface ReferenceBigList<K>

Overrides:

subList in class AbstractReferenceBigList<K>

Parameters:

from - the starting element (inclusive).
