LongBigListIterators
public static class LongBigListIterators.EmptyBigListIterator
extends java.lang.Object
implements LongBigListIterator, java.io.Serializable, java.lang.Cloneable
A class returning no elements and a type-specific big list iterator interface.

This class may be useful to implement your own in case you subclass a type-specific iterator.

      hasNext in interface java.util.Iterator<java.lang.Long>

    • hasPrevious

      public boolean hasPrevious()
      Description copied from interface: BidirectionalIterator
      Returns whether there is a previous element.
      Specified by:
      hasPrevious in interface BidirectionalIterator<java.lang.Long>
      Returns:
      whether there is a previous element.
      See Also:
      ListIterator.hasPrevious()

    • nextLong

      public long nextLong()
      Description copied from interface: LongIterator
      Returns the next element as a primitive type.
      Specified by:
      nextLong in interface LongIterator
      Specified by:
      nextLong in interface java.util.PrimitiveIterator.OfLong
      Returns:
      the next element in the iteration.
      See Also:
      Iterator.next()

    • 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<java.lang.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<java.lang.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()

    • skip

      public long skip​(long n)
      Description copied from interface: LongBigListIterator
      Skips the given number of elements.

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

      Specified by:
      skip in interface LongBigListIterator
      Parameters:
      n - the number of elements to skip.
      Returns:
      the number of elements actually skipped.
      See Also:
      Iterator.next()

    • 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.
      See Also:
      BidirectionalIterator.previous()

      Specified by:
      forEachRemaining in interface java.util.PrimitiveIterator.OfLong

    • forEachRemaining

      @Deprecated public void forEachRemaining​(java.util.function.Consumer<? super java.lang.Long> action)
