Description

Tested with: GHC 8.0.1

This is an internal implementation module that should never be used directly.

The module defines the Simulation monad that represents a computation within the simulation run.

A type class to lift the simulation computations to other computations.

Minimal complete definition

liftSimulation

Methods

liftSimulation :: Simulation a -> m a Source #

Lift the specified Simulation computation to another computation.

invokeSimulation :: Run -> Simulation a -> IO a Source #

Invoke the Simulation computation.

runSimulation :: Simulation a -> Specs -> IO a Source #

Run the simulation using the specified specs.

runSimulations :: Simulation a -> Specs -> Int -> [IO a] Source #

Run the given number of simulations using the specified specs, where each simulation is distinguished by its index simulationIndex.

runSimulationByIndex Source #

Arguments

:: Simulation a

the simulation model

-> Specs

the simulation specs

-> Int

the number of runs in series

-> Int

the index of the current run (started from 1)

-> IO a 

Run the simulation by the specified specs and run index in series.

Error Handling

catchSimulation :: Exception e => Simulation a -> (e -> Simulation a) -> Simulation a Source #

Exception handling within Simulation computations.

finallySimulation :: Simulation a -> Simulation b -> Simulation a Source #

A computation with finalization part like the finally function.

throwSimulation :: Exception e => e -> Simulation a Source #

Utilities

Memoization

memoSimulation :: Simulation a -> Simulation (Simulation a) Source #

Memoize the Simulation computation, always returning the same value within a simulation run.

Exceptions

data SimulationRetry Source #

An exception that signals that the current computation should be retried as possible, which feature may be supported by the simulation engine or not.

Constructors

SimulationRetry String

The exception to retry the computation.
