        Add (hopefully quickly) elements to this type-specific list.
        Specified by:

        Overrides:

        Parameters:
        index - the index at which to add elements.
        a - the array containing the elements.

        public void addElements​(int index,
                                long[] a,
                                int offset,
                                int length)
        Description copied from class: AbstractLongList
        Add (hopefully quickly) elements to this type-specific list.

        This is a trivial iterator-based implementation. It is expected that implementations will override this method with a more optimized version.

        Specified by:
        addElements in interface LongList
        Overrides:
        addElements in class AbstractLongList
        Parameters:
        index - the index at which to add elements.
        a - the array containing the elements.
        offset - the offset of the first element to add.
        length - the number of elements to add.
      • setElements

        public void setElements​(long[] a)
        Description copied from interface: LongList
        Set (hopefully quickly) elements to match the array given.
        Specified by:
        setElements in interface LongList
        Parameters:
        a - the array containing the elements.
      • setElements

        public void setElements​(int index,
                                long[] a)
        Description copied from interface: LongList
        Set (hopefully quickly) elements to match the array given.
        Specified by:
        setElements in interface LongList
        Parameters:
        index - the index at which to start setting elements.
        a - the array containing the elements.
      • setElements

        public void setElements​(int index,
                                long[] a,
                                int offset,
                                int length)
        Description copied from interface: LongList
        Set (hopefully quickly) elements to match the array given. Sets each in this list to the corresponding elements in the array, as if by
         ListIterator iter = listIterator(index);
         int i = 0;
         while (i < length) {
           iter.next();
           iter.set(a[offset + i++]);
         }
         
        However, the exact implementation may be more efficient, taking into account whether random access is faster or not, or at the discretion of subclasses, abuse internals.

        Overrides:
        setElements in class AbstractLongList

        index - the index at which to start setting elements.
        a - the array containing the elements
