trait Scheduler[T <: Txn[T]] 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
- abstract def cancel(token: Int)(implicit tx: T): Unit
Cancels a scheduled action.
Cancels a scheduled action. It is ok to use an old token that was already completed or cancelled.
- implicit abstract def cursor: Cursor[T]
- abstract def schedule(time: Long)(fun: (T) => Unit)(implicit tx: T): 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. - abstract def stepTag[A](fun: (T) => A): A
Performs a tagged transaction step.
Performs a tagged transaction step.

- abstract def time(implicit tx: T): Long
Logical time frame based on
TimeRef.SampleRateand with zero corresponding to creation time.Logical time frame based on
TimeRef.SampleRateand with zero corresponding to creation time. Frames elapsed with wall-clock but are stable within a transaction.
