Enclosing class:
DoubleIterators
public static class DoubleIterators.EmptyIterator

  • Method Details

    • hasNext

      public boolean hasNext()
      Specified by:
      hasNext in interface java.util.Iterator<java.lang.Double>
      Specified by:
      hasNext in interface java.util.ListIterator<java.lang.Double>

    • 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>
      Specified by:
      hasPrevious in interface java.util.ListIterator<java.lang.Double>
      Returns:
      whether there is a previous element.
      See Also:
      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 int nextIndex()
      Specified by:
      nextIndex in interface java.util.ListIterator<java.lang.Double>

    • previousIndex

      public int previousIndex()
      Specified by:
      previousIndex in interface java.util.ListIterator<java.lang.Double>

    • skip

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

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

      Specified by:
      skip in interface DoubleBidirectionalIterator
      Specified by:
      skip in interface DoubleIterator
      Specified by:
      skip in interface ObjectBidirectionalIterator<java.lang.Double>
      Specified by:
      skip in interface ObjectIterator<java.lang.Double>
      Parameters:
      n - the number of elements to skip.
      Returns:
      the number of elements actually skipped.
      See Also:
      Iterator.next()

    • back

      public int back​(int n)
      Description copied from interface: DoubleBidirectionalIterator
      Moves back for the given number of elements.

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

      Specified by:
      back in interface DoubleBidirectionalIterator
      Specified by:
      back in interface ObjectBidirectionalIterator<java.lang.Double>
      Parameters:
      n - the number of elements to skip back.
      Returns:
      the number of elements actually skipped.
      See Also:
      DoubleBidirectionalIterator.previous()

    • forEachRemaining

      public void forEachRemaining​(java.util.function.DoubleConsumer action)
      Specified by:

      Deprecated.
      Description copied from interface: DoubleIterator
      Specified by:
      forEachRemaining in interface DoubleIterator
      Specified by:
      forEachRemaining in interface java.util.Iterator<java.lang.Double>
      Specified by:
