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()
