runWait :: SimEnv -> ObsEnv -> Maybe Time -> Time -> [(Obs Bool, k)] -> [(ChoiceId, k)] -> (Time, ObsResult (WaitResult k)) Source #
When in a wait state there are three different things that can happen
one of the observables can become true, we can choose to take an anytime
option that is available to us.
There are two ways an observable can become true, one is due to a change in a primitive/external ovservable, and the other is via the passage of time.
Hence, overall, there are three events we are interested in while waiting.

Arguments
| :: Observations Double | time series for real primitive obs |
| -> Observations Bool | time series for bool primitive obs |
| -> Choices () |
|
| -> [(Time, k)] | optional timeouts |
| -> Time | initial time |
| -> ObsEnv | initial values of all primitive obs |
| -> TimedEvents (WaitEvent k) |
Take all three sources of events we are interested in and produce a unified event list
