Abstract Value Members

  1. abstract def set(v: A)(implicit txn: Context): Unit

    Permalink

    Performs a transactional write.

    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).

    v

    a value to store in the Ref.

    Exceptions thrown

    IllegalStateException if txn is not active.

  2. abstract def trySet(v: A)(implicit txn: Context): Boolean

    Permalink

    Performs a transactional write and returns true, or returns false.

    Performs a transactional write and returns true, or returns false. The STM implementation may choose to return false to reduce (not necessarily avoid) blocking. If no other threads are performing any transactional or atomic accesses then this method will succeed.

    Performs a transactional write.

    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
  ...
}
    v

    a value to store in the Ref.

    Exceptions thrown

    IllegalStateException if txn is not active.
