  1. trait Map[A, B] extends mutable.Map[A, B]

    A template trait for mutable maps that allow concurrent access.

    A template trait for mutable maps that allow concurrent access.

    This is a base trait for all Scala concurrent map implementations. It provides all of the methods a Map does, with the difference that all the changes are atomic. It also describes methods specific to concurrent maps.

    Note: The concurrent maps do not accept null for keys or values.

    A

    the key type of the map

    B

    the value type of the map

  2. final class TrieMap[K, V] extends Map[K, V] with mutable.MapLike[K, V, TrieMap[K, V]] with CustomParallelizable[(K, V), ParTrieMap[K, V]] with Serializable

    A concurrent hash-trie or TrieMap is a concurrent thread-safe lock-free implementation of a hash array mapped trie.

    A concurrent hash-trie or TrieMap is a concurrent thread-safe lock-free implementation of a hash array mapped trie. It is used to implement the concurrent map abstraction. It has particularly scalable concurrent insert and remove operations and is memory-efficient. It supports O(1), atomic, lock-free snapshots which are used to implement linearizable lock-free size, iterator and clear operations. The cost of evaluating the (lazy) snapshot is distributed across subsequent updates, thus making snapshot evaluation horizontally scalable.
