  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 from List.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.
  
  Specified by:

  public ObjectListIterator<K> listIterator()
  
  Description copied from interface: ReferenceList
  
  Returns a type-specific list iterator on the list.

  List.listIterator()
- iterator
  
  public ObjectListIterator<K> iterator()
  
  Description copied from interface: ReferenceCollection
  
  Returns a type-specific iterator on the elements of this collection.
  Note that this specification strengthens the one given in Iterable.iterator(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends Collection.
  
  Specified by:

  Overrides:
  
  iterator in class ReferenceCollections.EmptyCollection<K>
  
  Returns:
  
  a type-specific iterator on the elements of this collection.

  public ReferenceList<K> subList(int from, int to)
  
  Description copied from interface: ReferenceList
  
  Returns a type-specific view of the portion of this list from the index from, inclusive, to the index to, exclusive.
  Note that this specification strengthens the one given in List.subList(int,int).
  
  Specified by:
  
  subList in interface List<K>

  getElements in interface ReferenceList<K>
  
  Parameters:
  
  from - the start index (inclusive).

  Removes (hopefully quickly) elements of this type-specific list.
  
  Specified by:
  
  removeElements in interface ReferenceList<K>

  Description copied from interface: ReferenceList
  
  Add (hopefully quickly) elements to this type-specific list.
  
  Specified by:
  
  addElements in interface ReferenceList<K>
  
  Parameters:
  
  index - the index at which to add elements.
  
  a - the array containing the elements.
  
  offset - the offset of the first element to add.
  
  length - the number of elements to add.
- addElements
  
  public void addElements(int index, K[] a)
  
  Description copied from interface: ReferenceList
  
  Add (hopefully quickly) elements to this type-specific list.
  
  Specified by:
  
  addElements in interface ReferenceList<K>
  
  Parameters:
  
  index - the index at which to add elements.
  
  a - the array containing the elements.
- setElements
  
  public void setElements(K[] a)
  
  Description copied from interface: ReferenceList
  
  Set (hopefully quickly) elements to match the array given.
  
  Specified by:
  
  setElements in interface ReferenceList<K>
  
  Parameters:
  
  a - the array containing the elements.
- setElements
  
  public void setElements(int index, K[] a)
  
  Description copied from interface: ReferenceList
  
  Set (hopefully quickly) elements to match the array given.
  
  Specified by:
  
  setElements in interface ReferenceList<K>
  
  Parameters:
  
  index - the index at which to start setting elements.
  
  a - the array containing the elements.
- 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.

  index - the index at which to start setting elements.
  
  a - the array containing the elements

  length - the number of elements to add.
- size
  
  public void size(int s)
  
  Description copied from interface: ReferenceList
  
  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.
