Enclosing class:

ShortIterators

public abstract static class ShortIterators.AbstractIndexBasedListIterator
extends ShortIterators.AbstractIndexBasedIterator
implements ShortListIterator

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.

This class is only appropriate for sequences that are at most Integer.MAX_VALUE long. If your backing data store can be bigger then this, consider the equivalently named class in the type specific BigListSpliterators class.

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 Details

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<Short>

Specified by:

hasPrevious in interface ListIterator<Short>

Returns:

whether there is a previous element.

See Also:

• ListIterator.hasPrevious()

previousShort

public short previousShort()

Description copied from interface: ShortBidirectionalIterator

Returns the previous element as a primitive type.

Specified by:

previousShort in interface ShortBidirectionalIterator

Returns:

the previous element in the iteration.

See Also:

• ListIterator.previous()

nextIndex

public int nextIndex()

Specified by:

nextIndex in interface ListIterator<Short>

previousIndex

public int previousIndex()

Specified by:

previousIndex in interface ListIterator<Short>

add

public void add(short k)

Description copied from interface: ShortListIterator

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

This default implementation just throws an UnsupportedOperationException.

Specified by:

add in interface ShortListIterator

Parameters:

k - the element to insert.

See Also:

• ListIterator.add(Object)

set

public void set(short k)

Description copied from interface: ShortListIterator

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

Specified by:

set in interface ShortListIterator

Parameters:

k - the element used to replace the last element returned.

This default implementation just throws an UnsupportedOperationException.

See Also:

• ListIterator.set(Object)

back

public int back(int n)

Description copied from interface: ShortBidirectionalIterator

Moves back for the given number of elements.

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

Specified by:

back in interface ObjectBidirectionalIterator<Short>

Specified by:

back in interface ShortBidirectionalIterator

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

• ShortBidirectionalIterator.previous()
