Enclosing class:

LongBigListIterators

public abstract static class LongBigListIterators.AbstractIndexBasedBigListIterator
extends LongBigListIterators.AbstractIndexBasedBigIterator
implements LongBigListIterator

A skeletal implementation for a list-iterator backed by an index based data store. High performance concrete implementations (like the main ListIterator of ArrayList) generally should avoid using this and just implement the interface directly, but should be decent for less performance critical implementations.

As the abstract methods in this class are used in inner loops, it is generally a good idea to override the class as final as to encourage the JVM to inline them (or alternatively, override the abstract methods as final).

Method Summary

Modifier and Type	Method	Description
void	add(long k)	Inserts the specified element into the list (optional operation).
long	back(long n)	Moves back for the given number of elements.
boolean	hasPrevious()	Returns whether there is a previous element.
long	nextIndex()	Returns the index of the element that would be returned by a subsequent call to next.
long	previousIndex()	Returns the index of the element that would be returned by a subsequent call to previous.
long	previousLong()	Returns the previous element as a primitive type.
void	set(long k)	Replaces the last element returned by next() or previous() with the specified element (optional operation).

Method Details

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<Long>

Returns:

whether there is a previous element.

See Also:

• ListIterator.hasPrevious()

previousLong

public long previousLong()

Description copied from interface: LongBidirectionalIterator

Returns the previous element as a primitive type.

Specified by:

previousLong in interface LongBidirectionalIterator

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<Long>

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<Long>

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()

add

public void add(long k)

Description copied from interface: LongBigListIterator

Inserts the specified element into the list (optional operation).

Specified by:

add in interface LongBigListIterator

See Also:

• ListIterator.add(Object)

set

public void set(long k)

Description copied from interface: LongBigListIterator

Replaces the last element returned by next() or previous() with the specified element (optional operation).

Specified by:

set in interface LongBigListIterator

See Also:

• ListIterator.set(Object)

back

public long back(long n)

Description copied from interface: LongBigListIterator

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 LongBigListIterator

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

• BidirectionalIterator.previous()
