    • sort

      public void sort(Comparator<? super K> comparator)
      Description copied from interface: ObjectList
      Sorts this list using a sort assured to be stable.

      Pass null to sort using natural ordering.

      Unless a subclass specifies otherwise, the results of the method if the list is concurrently modified during the sort are unspecified.

      Specified by:

    • unstableSort

      public void unstableSort(Comparator<? super K> comparator)
      Description copied from interface: ObjectList
      Sorts this list using a sort not assured to be stable. This differs from List.sort(java.util.Comparator) in that the results are not assured to be stable, but may be a bit faster.

      Pass null to sort using natural ordering.

      Unless a subclass specifies otherwise, the results of the method if the list is concurrently modified during the sort are unspecified.
