Class CharBigListIterators.EmptyBigListIterator

java.lang.Object

it.unimi.dsi.fastutil.chars.CharBigListIterators.EmptyBigListIterator

All Implemented Interfaces:

BidirectionalIterator<java.lang.Character>, BigListIterator<java.lang.Character>, CharBidirectionalIterator, CharBigListIterator, CharIterator, ObjectBidirectionalIterator<java.lang.Character>, ObjectIterator<java.lang.Character>, java.io.Serializable, java.lang.Cloneable, java.util.Iterator<java.lang.Character>

Enclosing class:

CharBigListIterators

public static class CharBigListIterators.EmptyBigListIterator
extends java.lang.Object
implements CharBigListIterator, java.io.Serializable, java.lang.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 java.util.Iterator<java.lang.Character>

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<java.lang.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 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<java.lang.Character>

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<java.lang.Character>

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: CharBigListIterator

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 CharBigListIterator

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: CharBigListIterator

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 CharBigListIterator

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

See Also:

BidirectionalIterator.previous()

clone

public java.lang.Object clone()
