Class CharIterators.EmptyIterator

java.lang.Object

it.unimi.dsi.fastutil.chars.CharIterators.EmptyIterator

All Implemented Interfaces:

BidirectionalIterator<Character>, CharBidirectionalIterator, CharIterator, CharListIterator, ObjectBidirectionalIterator<Character>, ObjectIterator<Character>, Serializable, Cloneable, Iterator<Character>, ListIterator<Character>, PrimitiveIterator<Character, CharConsumer>

Enclosing class:

CharIterators

public static class CharIterators.EmptyIterator
extends Object
implements CharListIterator, 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<Character>

Specified by:

hasNext in interface ListIterator<Character>

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<Character>

Specified by:

hasPrevious in interface ListIterator<Character>

Returns:

whether there is a previous element.

See Also:

• ListIterator.hasPrevious()

nextChar

public char nextChar()

Description copied from interface: CharIterator

Returns the next element as a primitive type.

Specified by:

nextChar in interface CharIterator

Returns:

the next element in the iteration.

See Also:

• Iterator.next()

previousChar

public char previousChar()

Description copied from interface: CharBidirectionalIterator

Returns the previous element as a primitive type.

Specified by:

previousChar in interface CharBidirectionalIterator

Returns:

the previous element in the iteration.

See Also:

• ListIterator.previous()

nextIndex

public int nextIndex()

Specified by:

nextIndex in interface ListIterator<Character>

previousIndex

public int previousIndex()

Specified by:

previousIndex in interface ListIterator<Character>

skip

public int skip(int n)

Description copied from interface: CharBidirectionalIterator

Skips the given number of elements.

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

Specified by:

skip in interface CharBidirectionalIterator

Specified by:

skip in interface CharIterator

Specified by:

skip in interface ObjectBidirectionalIterator<Character>

Specified by:

skip in interface ObjectIterator<Character>

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: CharBidirectionalIterator

Moves back for the given number of elements.

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

Specified by:

back in interface CharBidirectionalIterator

Specified by:

back in interface ObjectBidirectionalIterator<Character>

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

See Also:

• CharBidirectionalIterator.previous()

forEachRemaining

public void forEachRemaining(CharConsumer action)

Description copied from interface: CharIterator

Performs the given action for each remaining element until all elements have been processed or the action throws an exception.

Specified by:

forEachRemaining in interface CharIterator

Specified by:

forEachRemaining in interface PrimitiveIterator<Character, CharConsumer>

Parameters:

action - the action to be performed for each element.

See Also:

• Iterator.forEachRemaining(java.util.function.Consumer)

forEachRemaining

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

Deprecated.

Description copied from interface: CharIterator

Specified by:

forEachRemaining in interface CharIterator

Specified by:

forEachRemaining in interface Iterator<Character>

clone

public Object clone()
