Class LongBigListIterators.EmptyBigListIterator

java.lang.Object

it.unimi.dsi.fastutil.longs.LongBigListIterators.EmptyBigListIterator

All Implemented Interfaces:

BidirectionalIterator<Long>, BigListIterator<Long>, LongBidirectionalIterator, LongBigListIterator, LongIterator, ObjectBidirectionalIterator<Long>, ObjectIterator<Long>, Serializable, Cloneable, Iterator<Long>, PrimitiveIterator<Long,LongConsumer>, PrimitiveIterator.OfLong

Enclosing class:

LongBigListIterators

public static class LongBigListIterators.EmptyBigListIterator
extends Object
implements LongBigListIterator, Serializable, Cloneable

A class returning no elements and a type-specific big list iterator interface.

This class may be useful to implement your own in case you subclass a type-specific iterator.

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<Long>

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<Long>

Returns:

whether there is a previous element.

See Also:

ListIterator.hasPrevious()

nextLong

public long nextLong()

Description copied from interface: LongIterator

Returns the next element as a primitive type.

Specified by:

nextLong in interface LongIterator

Specified by:

nextLong in interface PrimitiveIterator.OfLong

Returns:

the next element in the iteration.

See Also:

Iterator.next()

previousLong

public long previousLong()

Description copied from interface: LongBidirectionalIterator

Returns the previous element as a primitive type.

Specified by:

previousLong in interface LongBidirectionalIterator

Returns:

the previous element in the iteration.

See Also:

ListIterator.previous()

nextIndex

public long nextIndex()

Description copied from interface: BigListIterator

Returns the index of the element that would be returned by a subsequent call to next. (Returns list size if the list iterator is at the end of the list.)

Specified by:

nextIndex in interface BigListIterator<Long>

Returns:

the index of the element that would be returned by a subsequent call to next, or list size if list iterator is at end of list.

See Also:

ListIterator.nextIndex()

previousIndex

public long previousIndex()

Description copied from interface: BigListIterator

Returns the index of the element that would be returned by a subsequent call to previous. (Returns -1 if the list iterator is at the beginning of the list.)

Specified by:

previousIndex in interface BigListIterator<Long>

Returns:

the index of the element that would be returned by a subsequent call to previous, or -1 if list iterator is at beginning of list.

See Also:

ListIterator.previousIndex()

skip

public long skip(long n)

Description copied from interface: LongBigListIterator

Skips the given number of elements.

The effect of this call is exactly the same as that of calling next() for n times (possibly stopping if Iterator.hasNext() becomes false).

Specified by:

skip in interface LongBigListIterator

Parameters:

n - the number of elements to skip.

Returns:

the number of elements actually skipped.

See Also:

Iterator.next()

back

public long back(long n)

Description copied from interface: LongBigListIterator

Moves back for the given number of elements.

The effect of this call is exactly the same as that of calling previous() for n times (possibly stopping if BidirectionalIterator.hasPrevious() becomes false).

Specified by:

back in interface LongBigListIterator

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

See Also:

BidirectionalIterator.previous()

clone

public Object clone()

Overrides:

clone in class Object
