        Description copied from interface: CharList
        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.
        Specified by:
        setElements in interface CharList
        Parameters:
        index - the index at which to start setting elements.
        a - the array containing the elements
        offset - the offset of the first element to add.
        length - the number of elements to add.
      • size

        public void size​(int s)
        Description copied from interface: CharList
        Sets the size of this list.

        If the specified size is smaller than the current size, the last elements are discarded. Otherwise, they are filled with 0/null/false.

        size in interface CharList
        Parameters:
        s - the new size.
