Returns the size of this data structure as a long.

Specified by:

size64 in interface Size64

Returns:

the size of this data structure.

size

public void size(long size)

Description copied from interface: BigList

Sets the size of this big list.

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

size - the new size.

iterator

public ObjectBigListIterator<K> iterator()

Description copied from class: AbstractObjectBigList

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 AbstractObjectBigList.listIterator().

Specified by:

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

See Also:

Iterable.iterator()

listIterator

public ObjectBigListIterator<K> listIterator()

Description copied from class: AbstractObjectBigList

Returns a type-specific big-list iterator on this type-specific big list.

Note that this specification strengthens the one given in BigList.listIterator().

This implementation delegates to listIterator(0).

Specified by:

listIterator in interface BigList<K>

Specified by:

listIterator in interface ObjectBigList<K>

Overrides:

listIterator in class AbstractObjectBigList<K>

listIterator

public ObjectBigListIterator<K> listIterator(long index)

Description copied from class: AbstractObjectBigList

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

This implementation is based on the random-access methods.

Specified by:

listIterator in interface BigList<K>

Specified by:

Overrides:

listIterator in class AbstractObjectBigList<K>

Parameters:

index - 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.

See Also:

BigList.listIterator(long)

addAll

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

Description copied from class: AbstractObjectBigList

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

Overrides:

subList in class AbstractObjectBigList<K>

Parameters:
