- removeElements
  
  public void removeElements(int from, int to)
  
  Description copied from class: AbstractReferenceList
  
  Removes (hopefully quickly) elements of this type-specific list.
  This is a trivial iterator-based implementation. It is expected that implementations will override this method with a more optimized version.
  
  Specified by:
  
  removeElements in interface ReferenceList<K>
  
  Overrides:
  
  removeElements in class AbstractReferenceList<K>
  
  Parameters:
  
  from - the start index (inclusive).
  
  to - the end index (exclusive).
- addElements
  
  public void addElements(int index, K[] a)
  
  Description copied from class: AbstractReferenceList
  
  Add (hopefully quickly) elements to this type-specific list.
  This implementation delegates to the analogous method for array fragments.
  
  Specified by:
  
  addElements in interface ReferenceList<K>
  
  Overrides:
  
  addElements in class AbstractReferenceList<K>
  
  Parameters:
  
  index - the index at which to add elements.
  
  a - the array containing the elements.
- addElements
  
  public void addElements(int index, K[] a, int offset, int length)
  
  Description copied from class: AbstractReferenceList
  
  Add (hopefully quickly) elements to this type-specific list.
  This is a trivial iterator-based implementation. It is expected that implementations will override this method with a more optimized version.
  
  Specified by:
  
  addElements in interface ReferenceList<K>
  
  Overrides:
  
  addElements in class AbstractReferenceList<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.
- 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.
  Specified by:
  
  setElements in interface ReferenceList<K>
  
  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.

  public int size()
  
  Specified by:
  
  size in interface Collection<K>
  
  Specified by:
  
  size in interface List<K>
  
  Specified by:
  
  size in class AbstractCollection<K>
- size
  
  public void size(int size)
  
  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.
  
  Specified by:
  
  size in interface ReferenceList<K>
  
  Overrides:
  
  size in class AbstractReferenceList<K>
  
  Parameters:
  
  size - the new size.

  Description copied from class: AbstractReferenceList
  
  This implementation delegates to AbstractReferenceList.removeElements(int, int).
  
  Specified by:
  
  clear in interface Collection<K>
  
  Specified by:
  
  clear in interface List<K>
  
  Overrides:
  
  clear in class AbstractReferenceList<K>
