public void unstableSort(Comparator<? super K> comparator)
Description copied from interface:ReferenceList
Sorts this list using a sort not assured to be stable. This differs fromList.sort(java.util.Comparator)
in that the results are not assured to be stable, but may be a bit faster.Unless a subclass specifies otherwise, the results of the method if the list is concurrently modified during the sort are unspecified.

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
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:
