public interface LongBidirectionalIterator
extends LongIterator, ObjectBidirectionalIterator<java.lang.Long>

  • Method Details

    • previousLong

      long previousLong()
      Returns the previous element as a primitive type.
      Returns:
      the previous element in the iteration.
      See Also:
      ListIterator.previous()

    • previous

      @Deprecated default java.lang.Long previous()
      Deprecated.
      Please use the corresponding type-specific method instead.
      Returns the previous element from the collection.
      Specified by:
      previous in interface BidirectionalIterator<java.lang.Long>
      Returns:
      the previous element from the collection.
      See Also:
      ListIterator.previous()

    • 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 previous() for n times (possibly stopping if BidirectionalIterator.hasPrevious() becomes false).

      Specified by:
      back in interface ObjectBidirectionalIterator<java.lang.Long>
      Parameters:
      n - the number of elements to skip back.
      Returns:
      the number of elements actually skipped.
      See Also:
      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 LongIterator.next() for n times (possibly stopping if Iterator.hasNext() becomes false).

      Specified by:
      skip in interface LongIterator
      Specified by:
      skip in interface ObjectBidirectionalIterator<java.lang.Long>
      Specified by:
      skip in interface ObjectIterator<java.lang.Long>
      Parameters:
      n - the number of elements to skip.
      Returns:
      the number of elements actually skipped.

      Iterator.next()
