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.- Type Params
- 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. 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.
