Class IntIterators.EmptyIterator

java.lang.Object

it.unimi.dsi.fastutil.ints.IntIterators.EmptyIterator

All Implemented Interfaces:

BidirectionalIterator<Integer>, IntBidirectionalIterator, IntIterator, IntListIterator, ObjectBidirectionalIterator<Integer>, ObjectIterator<Integer>, Serializable, Cloneable, Iterator<Integer>, ListIterator<Integer>, PrimitiveIterator<Integer,IntConsumer>, PrimitiveIterator.OfInt

Enclosing class:

IntIterators

public static class IntIterators.EmptyIterator
extends Object
implements IntListIterator, Serializable, Cloneable

A class returning no elements and a type-specific 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<Integer>

Specified by:

hasNext in interface ListIterator<Integer>

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<Integer>

Specified by:

hasPrevious in interface ListIterator<Integer>

Returns:

whether there is a previous element.

See Also:

ListIterator.hasPrevious()

nextInt

public int nextInt()

Description copied from interface: IntIterator

Returns the next element as a primitive type.

Specified by:

nextInt in interface IntIterator

Specified by:

nextInt in interface PrimitiveIterator.OfInt

Returns:

the next element in the iteration.

See Also:

Iterator.next()

previousInt

public int previousInt()

Description copied from interface: IntBidirectionalIterator

Returns the previous element as a primitive type.

Specified by:

previousInt in interface IntBidirectionalIterator

Returns:

the previous element in the iteration.

See Also:

ListIterator.previous()

nextIndex

public int nextIndex()

Specified by:

nextIndex in interface ListIterator<Integer>

previousIndex

public int previousIndex()

Specified by:

previousIndex in interface ListIterator<Integer>

skip

public int skip(int n)

Description copied from interface: IntBidirectionalIterator

Skips the given number of elements.

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

Specified by:

skip in interface IntBidirectionalIterator

Specified by:

skip in interface IntIterator

Specified by:

skip in interface ObjectBidirectionalIterator<Integer>

Specified by:

skip in interface ObjectIterator<Integer>

Parameters:

n - the number of elements to skip.

Returns:

the number of elements actually skipped.

See Also:

Iterator.next()

back

public int back(int n)

Description copied from interface: IntBidirectionalIterator

Moves back for the given number of elements.

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

Specified by:

back in interface IntBidirectionalIterator

Specified by:

back in interface ObjectBidirectionalIterator<Integer>

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

See Also:

IntBidirectionalIterator.previous()

clone

public Object clone()

Overrides:

clone in class Object
