public static class DoubleBigListIterators.EmptyBigListIterator
extends java.lang.Object
implements DoubleBigListIterator, 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.

    • hasPrevious

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

      ListIterator.hasPrevious()
    • nextDouble

      public double nextDouble()
      Description copied from interface: DoubleIterator
      Returns the next element as a primitive type.
      Specified by:
      nextDouble in interface DoubleIterator
      Specified by:
      nextDouble in interface java.util.PrimitiveIterator.OfDouble
      Returns:
      the next element in the iteration.
      See Also:
      Iterator.next()
    • previousDouble

      public double previousDouble()
      Description copied from interface: DoubleBidirectionalIterator
      Returns the previous element as a primitive type.
      Specified by:
      previousDouble in interface DoubleBidirectionalIterator
      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.Double>
      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.Double>
      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: DoubleBigListIterator
      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 DoubleBigListIterator
      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: DoubleBigListIterator
      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 DoubleBigListIterator
      Parameters:
      n - the number of elements to skip back.
      Returns:
      the number of elements actually skipped.
      See Also:
      BidirectionalIterator.previous()

      forEachRemaining in interface java.util.PrimitiveIterator<java.lang.Double,​java.util.function.DoubleConsumer>
      Specified by:
      forEachRemaining in interface java.util.PrimitiveIterator.OfDouble
    • forEachRemaining

      @Deprecated public void forEachRemaining​(java.util.function.Consumer<? super java.lang.Double> action)
      Deprecated.
      Description copied from interface: DoubleIterator
      Specified by:
      forEachRemaining in interface DoubleIterator
      Specified by:
