Performs a transactional write. The new value will not be visible by any other threads until (and unless) txn successfully commits. Equivalent to update(v).

Performs a transactional write. The new value will not be visible by any other threads until (and unless) txn successfully commits. Equivalent to set(v).

Example:

  val x = Ref(0)
  atomic { implicit t =>

    x() = 10 // perform a write inside a transaction
    ...
  }
