public interface ObjectBidirectionalIterator<K>
extends ObjectIterator<K>, BidirectionalIterator<K>

A type-specific bidirectional iterator; provides an additional method to avoid (un)boxing, and the possibility to skip elements backwards.

Method Details

back

default int back(int n)

Moves back for the given number of elements.

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

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

See Also:

• BidirectionalIterator.previous()

skip

default int skip(int n)

Skips the given number of elements.

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

Specified by:

skip in interface ObjectIterator<K>

Parameters:

n - the number of elements to skip.

Returns:

the number of elements actually skipped.

• Iterator.next()
