Constructor Detail

ObjectSubList

                     long from,
                     long to)

Method Detail

add

public boolean add(K k)

Description copied from class: AbstractObjectBigList

Ensures that this collection contains the specified element (optional operation). Returns true if this collection changed as a result of the call. (Returns false if this collection does not permit duplicates and already contains the specified element.)

Collections that support this operation may place limitations on what elements may be added to this collection. In particular, some collections will refuse to add null elements, and others will impose restrictions on the type of elements that may be added. Collection classes should clearly specify in their documentation any restrictions on what elements may be added.

If a collection refuses to add a particular element for any reason other than that it already contains the element, it must throw an exception (rather than returning false). This preserves the invariant that a collection always contains the specified element after this call returns.

This implementation always throws an UnsupportedOperationException.

This implementation delegates to the type-specific version of BigList.add(long, Object).

Specified by:

add in interface Collection<K>

Overrides:

add in class AbstractObjectBigList<K>

Parameters:

k - element whose presence in this collection is to be ensured

Returns:

true if this collection changed as a result of the call

add

public void add(long index,
                K k)

Description copied from class: AbstractObjectBigList

Inserts the specified element at the specified position in this big list (optional operation).

This implementation always throws an UnsupportedOperationException.

Specified by:

add in interface BigList<K>

Overrides:

add in class AbstractObjectBigList<K>

Parameters:

index - a position in the big list.

k - an element to be inserted.

See Also:

List.add(int,Object)

addAll

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

Description copied from class: AbstractObjectBigList

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

Specified by:

addAll in interface BigList<K>

Overrides:

addAll in class AbstractObjectBigList<K>

Parameters:

index - 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)

get

public K get(long index)

Description copied from interface: BigList

Returns the element at the specified position.

Specified by:

get in interface BigList<K>

Parameters:

index - a position in the big list.

Returns:

the element at the specified position.

See Also:

List.get(int)

remove

public K remove(long index)

Description copied from class: AbstractObjectBigList

Removes the element at the specified position.

This implementation always throws an UnsupportedOperationException.

Specified by:

remove in interface BigList<K>

Overrides:

remove in class AbstractObjectBigList<K>

Parameters:

index - a position in the big list.

Returns:

the element previously at the specified position.

See Also:

List.remove(int)

set

public K set(long index,
             K k)

Description copied from class: AbstractObjectBigList

Replaces the element at the specified position in this big list with the specified element (optional operation).

This implementation always throws an UnsupportedOperationException.

Specified by:

set in interface BigList<K>

Overrides:

set in class AbstractObjectBigList<K>

Parameters:

index - a position in the big list.

k - the element to be stored at the specified position.

Returns:

the element previously at the specified positions.

See Also:

List.set(int,Object)

size64

public long size64()

Description copied from interface: Size64

Returns the size of this data structure as a long.

Specified by:

size64 in interface Size64

Returns:

the size of this data structure.

getElements

public void getElements(long from,
                        Object[][] a,

                        long length)

Description copied from class: AbstractObjectBigList

Copies (hopefully quickly) elements of this type-specific big list into the given big array.

This is a trivial iterator-based implementation. It is expected that implementations will override this method with a more optimized version.

Overrides:

getElements in class AbstractObjectBigList<K>

Parameters:

from - the start index (inclusive).

a - the destination big array.

offset - the offset into the destination big array where to store the first element copied.

length - the number of elements to be copied.

removeElements

                           long to)

Description copied from class: AbstractObjectBigList

Removes (hopefully quickly) elements of this type-specific big list.

This is a trivial iterator-based implementation. It is expected that implementations will override this method with a more optimized version.

Specified by:

removeElements in interface ObjectBigList<K>

Overrides:

removeElements in class AbstractObjectBigList<K>

Parameters:

from - the start index (inclusive).

to - the end index (exclusive).

addElements

public void addElements(long index,
                        K[][] a,

                        long length)

Description copied from class: AbstractObjectBigList

Add (hopefully quickly) elements to this type-specific big list.

This is a trivial iterator-based implementation. It is expected that implementations will override this method with a more optimized version.

Specified by:

addElements in interface ObjectBigList<K>

Overrides:

addElements in class AbstractObjectBigList<K>

Parameters:

index - the index at which to add elements.

listIterator in interface BigList<K>

Specified by:

listIterator in interface ObjectBigList<K>

Overrides:

listIterator in class AbstractObjectBigList<K>

Parameters:

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