Class NodeCachingLinkedList<E>

  • All Implemented Interfaces:
    Serializable, Iterable<E>, Collection<E>, List<E>
    public class NodeCachingLinkedList<E>
extends AbstractLinkedList<E>
implements Serializable
    A List 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.
