Engine

the simulation environment

The error that made the simulation fail, if any.

The registered output monitors, as a read-only view.

The current simulation status.

The current step (thread-safe).

The current simulation time (thread-safe).

Adds an output monitor to track simulation events.

Moves the simulation forward until the given step is reached.

Moves the simulation forward until the given time is reached.

Pauses the simulation.

Resumes the simulation.

Notifies the simulation that a reaction host has registered reactionToAdd. Model code should register the reaction through its host; the host invokes this callback after membership actually changes. Adding a node invokes this callback once for each reaction already hosted by that node; node and topology changes have no separate simulation callback.

Marks reactionToUpdate as a reaction whose observed scheduling inputs changed. The notification is synchronous and must originate on the simulation thread. The engine refreshes each affected reaction once when the enclosing model mutation completes.

Notifies the simulation that a reaction host has unregistered reactionToRemove. Model code should unregister the reaction through its host; the host invokes this callback after membership actually changes. Removing a node invokes this callback once for each hosted reaction before disposing it.

Internal method to run the simulation loop. Implementations must provide initialize, doStep, and hooks for run cycle.

Runs an existing Simulation in the current thread.

Schedules a task for execution.

Run the simulation this environment owns.

Terminates the simulation.

Converts a Simulation to a SimulationSurrogate.

Waits for the simulation to reach a given status.
