Simulation.Aivika.Trans.Internal.Types
Description
Tested with: GHC 8.0.1
It defines the implementation details of some types. You should never use it in ordinary simulation models. The module is destined for those who will extend the library.

newtype Parameter m a Source #
The Parameter monad that allows specifying the model parameters.
For example, they can be used when running the Monte-Carlo simulation.
In general, this monad is very useful for representing a computation which is external relative to the model itself.
Instances
newtype Simulation m a Source #
A value in the Simulation monad represents a computation
within the simulation run.
Constructors
| Simulation (Run m -> m a) |
Instances
A value in the Dynamics monad represents a polymorphic time varying function
defined in the whole spectrum of time values as a single entity. It is ideal for
numerical approximating integrals.
Instances
A value in the Event monad transformer represents a polymorphic time varying
function which is strongly synchronized with the event queue.
Instances

Defines how the events are processed.

Methods
newEventQueue :: Specs m -> m (EventQueue m) Source #
Create a new event queue by the specified specs with simulation session.
enqueueEvent :: Double -> Event m () -> Event m () Source #
Enqueue the event which must be actuated at the specified time.
runEvent :: Event m a -> Dynamics m a Source #
Run the EventT computation in the current simulation time
within the DynamicsT computation involving all pending
CurrentEvents in the processing too.
runEventWith :: EventProcessing -> Event m a -> Dynamics m a Source #
Run the EventT computation in the current simulation time
within the DynamicsT computation specifying what pending events
should be involved in the processing.
eventQueueCount :: Event m Int Source #
Return the number of pending events that should be yet actuated.
