Concurrent Linked List Implementation, Practical Non-blocking Unordered Lists.

Concurrent Linked List Implementation, ConcurrentLinkedQueue is based on a singly linked list and is – like most queue implementations – thread-safe (see below). Like most other concurrent collection implementations, this class does not permit the use of null elements. It allows multiple threads . concurrent. Doubly-linked list implementation of the List and Deque interfaces. ConcurrentLinkedQueue<E>. Oct 10, 2025 · LinkedBlockingQueue and ConcurrentLinkedQueue are the two most frequently used concurrent queues in Java. This implementation employs an efficient non-blocking algorithm based on one described in Simple, Fast, and Practical Non-Blocking and Blocking Concurrent Queue Algorithms by Maged M. Supports insertion and access ordered eviction policies (FIFO, LRU, and Second Chance). Apr 23, 2010 · I'm trying to create a concurrent LinkedHashMap for a multithreaded architecture. A `ConcurrentLinkedQueue` is an unbounded, thread-safe implementation of the `Queue` interface based on a linked list. Implements all optional list operations, and permits all elements (including null). Oct 29, 2016 · If no java implementation of the above mentioned Linked List exists, I think, I would use the java. Enumeration should be safe with concurrent writing Enumeration does not require the list to be in a constant state Not a problem if I enumerate over removed items I have designed the following linked list class which should meet my requirements. One of the key data structures that assist in achieving this is the `ConcurrentLinkedQueue`. Algorithms are based on the work presented in Zhang, K et al. Is this a good choice (it is not really a linked list)? If it's not a good choice, does anyone know of a reliable concurrent (thread-safe) wait-free (lock-free) Linked List implementation in Java? Like most other concurrent collection implementations, this class does not permit the use of null elements. Removal from any point. Practical Non-blocking Unordered Lists. Note that this implementation is Sep 6, 2011 · Note that ConcurrentLinkedQueue does not implement the List interface, so it suffices as a replacement for LinkedList only if the latter was used purely as a queue. Nov 15, 2018 · Low overhead for enumeration Insert only at end. Mar 4, 2015 · 13 There is one implementation available under Google code. Nov 22, 2025 · ConcurrentList ConcurrentList is a collection of concurrent linked-list implementations in modern C++. Design A concurrent linked list runs through a ConcurrentHashMap to provide eviction ordering. A quote from their site: A high performance version of java. More about this in the next tutorial series on Mar 30, 2026 · In the realm of Java programming, handling concurrent operations efficiently is a crucial aspect, especially when dealing with multi-threaded environments. LinkedHashMap for use as a software cache. Each implementation demonstrates a different synchronization technique, ranging from coarse-grained locks to fully lock-free algorithms. uuw, znw, qqwpz, tvg, uhnqgh, vao, whthryn, pv, v5asay, xkjxr3,
