TArray

Performs a transactional read of the indexth element of this transactional array. Equivalent to refs(index).get.

Returns the length of this TArray, which does not change.

Returns a sequence of Ref instances that are backed by elements of this TArray. All operations on the contained Refs are supported.

As an example, the following code tests whether a(i) is greater than 10 without requiring the transaction to roll back for all writes to a(i):

  atomic { implicit t =>
    if (a.refs(i).getWith( _ > 10 )) {
      ... lots of stuff
    }
  }

Returns a TArray.View that allows access to the contents of this TArray without requiring that an InTxn be available. See Ref.View.

Performs a transactional write to the indexth element of this transactional array. Equivalent to refs(index).set(v).

Returns a string representation of the transactional value in this instance for debugging convenience. The Ref reads (and writes) performed while constructing the result will be discarded before returning. This method works fine outside a transaction.

If this method is called from within a transaction that is already doomed (status Txn.Rolledback), a string describing the reason for the outer transaction's rollback will be returned.

Returns some value that is suitable for examination in a debugger, or returns a Txn.RollbackCause if called from inside a doomed atomic block.
