TArray

trait TArray[A] extends TxnDebuggable

Bulk transactional storage, roughly equivalent to Array[Ref[T]] but potentially much more space efficient. Elements can be read and written directly, or the refs method can be used to obtain transient Ref instances backed by the elements of the TArray.

Abstract Value Members

  1. abstract def apply(index: Int)(implicit txn: InTxn): A

    Performs a transactional read of the indexth element of this transactional array.

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

  2. abstract def dbgStr: String

    Returns a string representation of the transactional value in this instance for debugging convenience.

    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.

    TxnDebuggable
  3. abstract def dbgValue: Any

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

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

  4. abstract def length: Int

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

  5. abstract def refs: collection.immutable.IndexedSeq[Ref[A]]

    Returns a sequence of Ref instances that are backed by elements of this TArray.

    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
    }
    }
  6. abstract def single: View[A]

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

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

  7. abstract def update(index: Int, v: A)(implicit txn: InTxn): Unit

    Performs a transactional write to the indexth element of this transactional array.

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