    • Method Detail

      • 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.
