Class DoubleBigListIterators.EmptyBigListIterator

java.lang.Object

it.unimi.dsi.fastutil.doubles.DoubleBigListIterators.EmptyBigListIterator

All Implemented Interfaces:

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

Enclosing class:

DoubleBigListIterators

public static class DoubleBigListIterators.EmptyBigListIterator
extends Object
implements DoubleBigListIterator, 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 Details

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<Double>

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<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 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<Double>

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<Double>

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: DoubleBigListIterator

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 DoubleBigListIterator

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: DoubleBigListIterator

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 DoubleBigListIterator

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

See Also:

• BidirectionalIterator.previous()

clone

public Object clone()

forEachRemaining

public void forEachRemaining(DoubleConsumer action)

Specified by:

forEachRemaining in interface PrimitiveIterator<Double, DoubleConsumer>

Specified by:

forEachRemaining in interface PrimitiveIterator.OfDouble

forEachRemaining

@Deprecated
public void forEachRemaining(Consumer<? super Double> action)

Deprecated.

Description copied from interface: DoubleIterator

Specified by:

forEachRemaining in interface DoubleIterator

Specified by:

forEachRemaining in interface Iterator<Double>

Specified by:

forEachRemaining in interface PrimitiveIterator.OfDouble
