Simulation.Aivika.IO.Signal

Tested with: GHC 8.0.1

This module allows collecting the signal history in a more optimal way than it suggests the general implementation.

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 :: Signal IO a -> Composite IO (SignalHistory IO a)

Create a history of the signal values.

newSignalHistoryStartingWith :: Maybe a -> Signal IO a -> Composite IO (SignalHistory IO a)

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

readSignalHistory :: SignalHistory IO a -> Event IO (Array Int Double, Array Int a)

Read the history of signal values.
