Class DoubleIterators.EmptyIterator

java.lang.Object

it.unimi.dsi.fastutil.doubles.DoubleIterators.EmptyIterator

All Implemented Interfaces:

BidirectionalIterator<Double>, DoubleBidirectionalIterator, DoubleIterator, DoubleListIterator, ObjectBidirectionalIterator<Double>, ObjectIterator<Double>, Serializable, Cloneable, Iterator<Double>, ListIterator<Double>, PrimitiveIterator<Double,DoubleConsumer>, PrimitiveIterator.OfDouble

Enclosing class:

DoubleIterators

public static class DoubleIterators.EmptyIterator
extends Object
implements DoubleListIterator, 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 Details

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<Double>

Specified by:

hasNext in interface ListIterator<Double>

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<Double>

Specified by:

hasPrevious in interface ListIterator<Double>

Returns:

whether there is a previous element.

See Also:

ListIterator.hasPrevious()

nextDouble

public double nextDouble()

Description copied from interface: DoubleIterator

Returns the next element as a primitive type.

Specified by:

nextDouble in interface DoubleIterator

Specified by:

nextDouble in interface PrimitiveIterator.OfDouble

Returns:

the next element in the iteration.

See Also:

Iterator.next()

previousDouble

public double previousDouble()

Description copied from interface: DoubleBidirectionalIterator

Returns the previous element as a primitive type.

Specified by:

previousDouble in interface DoubleBidirectionalIterator

Returns:

the previous element in the iteration.

See Also:

ListIterator.previous()

nextIndex

public int nextIndex()

Specified by:

nextIndex in interface ListIterator<Double>

previousIndex

public int previousIndex()

Specified by:

previousIndex in interface ListIterator<Double>

skip

public int skip(int n)

Description copied from interface: DoubleBidirectionalIterator

Skips the given number of elements.

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

Specified by:

skip in interface DoubleBidirectionalIterator

Specified by:

skip in interface DoubleIterator

Specified by:

skip in interface ObjectBidirectionalIterator<Double>

Specified by:

skip in interface ObjectIterator<Double>

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: DoubleBidirectionalIterator

Moves back for the given number of elements.

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

Specified by:

back in interface DoubleBidirectionalIterator

Specified by:

back in interface ObjectBidirectionalIterator<Double>

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

See Also:

DoubleBidirectionalIterator.previous()

clone

public Object clone()
