@Deprecated(since="2021-04-30") public class NodeCachingLinkedList extends AbstractLinkedList implements java.io.Serializable
Deprecated.Commons Collections 3 is in maintenance mode. Commons Collections 4 should be used instead.AList
implementation that stores a cache of internal Node objects in an effort to reduce wasteful object creation.A linked list creates one Node for each item of data added. This can result in a lot of object creation and garbage collection. This implementation seeks to avoid that by maintaining a store of cached nodes.
This implementation is suitable for long-lived lists where both add and remove are used. Short-lived lists, or lists which only grow will have worse performance using this class.
Note that this implementation is not synchronized.

- Commons Collections 3.0
