Method Details

add

public boolean add(long k)

Description copied from class: AbstractLongList

Ensures that this collection contains the specified element (optional operation).

Specified by:

add in interface LongCollection

Specified by:

add in interface LongList

Overrides:

add in class AbstractLongList

See Also:

• Collection.add(Object)

add

public void add(int index,
 long k)

Description copied from class: AbstractLongList

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

Specified by:

add in interface LongList

Overrides:

add in class AbstractLongList

See Also:

• List.add(int,Object)

addAll

public boolean addAll(int index,
 Collection<? extends Long> c)

Description copied from class: AbstractLongList

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

Specified by:

addAll in interface List<Long>

Overrides:

addAll in class AbstractLongList

getLong

public long getLong(int index)

Description copied from interface: LongList

Returns the element at the specified position in this list.

Specified by:

getLong in interface LongList

See Also:

• List.get(int)

removeLong

public long removeLong(int index)

Description copied from class: AbstractLongList

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

Specified by:

removeLong in interface LongList

Overrides:

removeLong in class AbstractLongList

See Also:

• List.remove(int)

set

public long set(int index,
 long k)

Description copied from class: AbstractLongList

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

Specified by:

set in interface LongList

Overrides:

set in class AbstractLongList

See Also:

• List.set(int,Object)

size

public int size()

Specified by:

size in interface Collection<Long>

Specified by:

size in interface List<Long>

Specified by:

size in class AbstractCollection<Long>

getElements

public void getElements(int from,
 long[] a,
 int offset,
 int length)

Description copied from class: AbstractLongList

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

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

Specified by:

getElements in interface LongList

Overrides:

getElements in class AbstractLongList

Parameters:

from - the start index (inclusive).

a - the destination array.

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

length - the number of elements to be copied.

removeElements

public void removeElements(int from,
 int to)

Description copied from class: AbstractLongList

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

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

Specified by:

removeElements in interface LongList

Overrides:

removeElements in class AbstractLongList

Parameters:

from - the start index (inclusive).

to - the end index (exclusive).

addElements

public void addElements(int index,
 long[] a,
 int offset,
 int length)

Description copied from class: AbstractLongList

Add (hopefully quickly) elements to this type-specific 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 LongList

Overrides:

addElements in class AbstractLongList

Parameters:

index - the index at which to add elements.

a - the array containing the elements.

offset - the offset of the first element to add.

length - the number of elements to add.

setElements

public void setElements(int index,
 long[] a,
 int offset,
 int length)

Description copied from interface: LongList

Set (hopefully quickly) elements to match the array given. Sets each in this list to the corresponding elements in the array, as if by

 ListIterator iter = listIterator(index);
 int i = 0;
 while (i < length) {
        iter.next();
        iter.set(a[offset + i++]);
 }
 

However, the exact implementation may be more efficient, taking into account whether random access is faster or not, or at the discretion of subclasses, abuse internals.

Specified by:

setElements in interface LongList

Overrides:

setElements in class AbstractLongList

Parameters:

index - the index at which to start setting elements.

a - the array containing the elements

offset - the offset of the first element to add.

length - the number of elements to add.

listIterator

public LongListIterator listIterator(int index)

Description copied from class: AbstractLongList

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

Specified by:

Specified by:

listIterator in interface LongList

Overrides:

listIterator in class AbstractLongList

See Also:

• List.listIterator(int)

spliterator

public LongSpliterator spliterator()

Description copied from interface: LongList

Returns a type-specific spliterator on the elements of this list.
