/**
|
|
* Linked list implementation of the List interface. In addition to the
|
|
* methods of the List interface, this class provides access to the first
|
|
* and last list elements in O(1) time for easy stack, queue, or double-ended
|
|
* queue (deque) creation. The list is doubly-linked, with traversal to a
|
|
* given index starting from the end closest to the element.<p>
|
|
*
|
|
* LinkedList is not synchronized, so if you need multi-threaded access,
|
|
* consider using:<br>
|
|
* <code>List l = Collections.synchronizedList(new LinkedList(...));</code>
|
|
* <p>
|
|
*
|
|
* The iterators are <i>fail-fast</i>, meaning that any structural
|
|
* modification, except for <code>remove()</code> called on the iterator
|
|
* itself, cause the iterator to throw a
|
|
* {@link ConcurrentModificationException} rather than exhibit
|
|
* non-deterministic behavior.
