    • setElements

      public void setElements(int index, K[] a, int offset, int length)
      Description copied from interface: ReferenceList
      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.

      setElements in interface ReferenceList<K>
      Parameters:
      index - the index at which to start setting elements.
