public long removeLong(int i)

Description copied from class: AbstractLongList

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

This implementation always throws an UnsupportedOperationException.

Specified by:

removeLong in interface LongList

Overrides:

removeLong in class AbstractLongList

See Also:

List.remove(int)

contains

public boolean contains(long k)

Description copied from class: AbstractLongList

Returns true if this list contains the specified element.

This implementation delegates to indexOf().

iterator

public LongListIterator iterator()

Description copied from class: AbstractLongList

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 AbstractLongList.listIterator().

Specified by:

Specified by:

iterator in interface List<Long>

Specified by:

iterator in interface LongCollection

Specified by:

Overrides:

iterator in class AbstractLongList

Returns:

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

See Also:

Iterable.iterator()

listIterator

public LongListIterator listIterator(int i)

Description copied from class: AbstractLongList

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 List<Long>

Specified by:

listIterator in interface LongList

Overrides:

listIterator in class AbstractLongList

See Also:

List.listIterator(int)

subList

public LongList subList(int from,
                        int to)

Description copied from interface: LongList
