scala.collection.concurrent (original) (raw)

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.

Type parameters

K

the key type of the map

V

the value type of the map

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.
