Insert a new StateFunction at the end of the processing chain for the given state. If the stateTimeout parameter is set, entering this state without a differing explicit timeout setting will trigger a StateTimeout event; the same is true when using #stay.
- stateName
designator for the state
- stateTimeout
default state timeout for this state
- stateFunction
partial function describing response to input

- final def setTimer(name: String, msg: Any, timeout: Duration, repeat: Boolean): Unit
Schedule named timer to deliver message after given delay, possibly repeating.
Schedule named timer to deliver message after given delay, possibly repeating. Any existing timer with the same name will automatically be canceled before adding the new timer.
- name
identifier to be used with cancelTimer()
- msg
message to be delivered
- timeout
delay of first message delivery and between subsequent messages
- repeat
send once if false, scheduleAtFixedRate if true

(Since version 2.6.0) Use startSingleTimer, startTimerWithFixedDelay or startTimerAtFixedRate instead. This has the same semantics as startTimerAtFixedRate, but startTimerWithFixedDelay is often preferred.
