AbstractLinkedList ("The Adobe AEM Quickstart and Web Application.")

java.lang.Object
- org.apache.commons.collections4.list.AbstractLinkedList<E>

All Implemented Interfaces:

java.lang.Iterable<E>, java.util.Collection<E>, java.util.List<E>

Direct Known Subclasses:

CursorableLinkedList, NodeCachingLinkedList
```
public abstract class AbstractLinkedList<E>
extends java.lang.Object
implements java.util.List<E>
```
An abstract implementation of a linked list which provides numerous points for subclasses to override.
Overridable methods are provided to change the storage node and to change how nodes are added to and removed. Hopefully, all you need for unusual subclasses is here.

Since:

3.0

    This implementation iterates over the elements of this list, checking each element in turn to see if it's contained in coll. If it's contained, it's removed from this list. As a consequence, it is advised to use a collection type for coll that provides a fast (e.g. O(1)) implementation of Collection.contains(Object).
