Description copied from interface:ObjectList
Set (hopefully quickly) elements to match the array given. Sets each in this list to the corresponding elements in the array, as if by
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.ListIterator iter = listIterator(index); int i = 0; while (i < length) { iter.next(); iter.set(a[offset + i++]); }
- Specified by:
