trait Scheduler[S <: Sys[S]] extends AnyRef

A Scheduler uses a logical frame clock to execute functions transactionally at specific times. It is parametrized in S in order to perform transactions, but it does not store any state that would need the scheduler to be handled with stm.Source. It can be safely stored in a regular value.

Abstract Value Members

  1. abstract def cancel(token: Int)(implicit tx: S.Tx): Unit

    Cancels a scheduled action.

    Cancels a scheduled action. It is ok to use an old token that was already completed or cancelled.

  2. implicit abstract def cursor: Cursor[S]
  3. abstract def schedule(time: Long)(fun: (S.Tx) ⇒ Unit)(implicit tx: S.Tx): Int

    Schedules the execution of a function at a given time.

    Schedules the execution of a function at a given time. Time is given as an "absolute" frame in the sense of AuralContext.time. Returns a token that can be used to cancel the action. The token is >= 0.

  4. abstract def stepTag[A](fun: (S.Tx) ⇒ A): A

    Performs a tagged transaction step.

  5. abstract def time(implicit tx: S.Tx): Long

    Logical time frame based on TimeRef.SampleRate and with zero corresponding to creation time.

    Logical time frame based on TimeRef.SampleRate and with zero corresponding to creation time. Frames elapsed with wall-clock but are stable within a transaction.
