- abstract def stepTag[A](systemTimeNanos: Long)(fun: (T) => A): A
Issues a new transaction (executor), tagged with the given time referring to "now", runs the function argument on it, and returns the result.
Issues a new transaction (executor), tagged with the given time referring to "now", runs the function argument on it, and returns the result.
The tagging can be used for latency based circumstances, such as scheduling OSC bundles on a sound server.
- systemTimeNanos
Time in nano-seconds since midnight, January 1, 1970 UTC. E.g.
System.currentTimeMillis() * 1000000000L(possibly adding nano-seconds fraction).
