Simulation.Aivika.IO.Signal

Tested with: GHC 8.0.1

This module allows collecting the signal history.

Signal History

data SignalHistory m a

Represents the history of the signal values.

signalHistorySignal :: SignalHistory m a -> Signal m a

The signal for which the history is created.

newSignalHistory :: (MonadDES m, MonadIO m, MonadTemplate m) => Signal m a -> Event m (SignalHistory m a)

Create a history of the signal values.

newSignalHistoryStartingWith :: (MonadDES m, MonadIO m, MonadTemplate m) => Maybe a -> Signal m a -> Event m (SignalHistory m a)

Create a history of the signal values starting with the optional initial value.

readSignalHistory :: (MonadDES m, MonadIO m, MonadTemplate m) => SignalHistory m a -> Event m (Array Int Double, Array Int a)

Read the history of signal values.
