AVxcelerate Simulation Framework 2026 R1 SP01

Class simulation_framework::core::SimRunner

Last update: 22.04.2026

Definition: core/service/sim_runner/sim_runner.h (line 27)

Simulation runner with external control logic.

The SimRunner class implements the ISimRunner interface and provides methods to control the flow of a simulation, including starting, pausing, stepping, and terminating it. Internally, it delegates these operations to a SimRunnerImpl object.

Public functions

Function ~SimRunner

simulation_framework::core::SimRunner::~SimRunner()

Destructor for SimRunner.

Return type:

Function SimRunner

simulation_framework::core::SimRunner::SimRunner(std::unique_ptr< lifecycle::ISimulationInstance > sim_instance)

Constructs a SimRunner with a simulation instance.

Parameters:

  • sim_instance: A unique pointer to the simulation instance to control.

Parameters:

Return type:

Function Run

StateFeedback simulation_framework::core::SimRunner::Run() override

Executes the simulation and changes the state to kRunning.

The simulation runs until the scenario ends unless paused or stopped by the user.

Returns:

A StateFeedback object containing execution status and error information, if any.

Return type: StateFeedback

Reimplements: Run

Function Pause

StateFeedback simulation_framework::core::SimRunner::Pause() override

Pauses the simulation.

If the simulation is in the kRunning state, it transitions to the kPaused state.

Returns:

A StateFeedback object containing the status of the pause operation.

Return type: StateFeedback

Reimplements: Pause

Function Resume

StateFeedback simulation_framework::core::SimRunner::Resume() override

Resumes the simulation.

The simulation state changes from kPaused back to kRunning.

Returns:

A StateFeedback object containing the status of the resume operation.

Return type: StateFeedback

Reimplements: Resume

Function StepN

StateFeedback simulation_framework::core::SimRunner::StepN(int n) override

Steps the simulation forward by a specified number of frames.

Parameters:

  • n: The number of simulation steps to execute.

Returns:

A StateFeedback object containing the status of the step operation.

Parameters:

Return type: StateFeedback

Reimplements: StepN

Function Stop

StateFeedback simulation_framework::core::SimRunner::Stop() override

Stops the simulation immediately.

The simulation state resets to kInitialized.

Returns:

A StateFeedback object containing the status of the stop operation.

Return type: StateFeedback

Reimplements: Stop

Function Terminate

StateFeedback simulation_framework::core::SimRunner::Terminate() override

Terminates the simulation.

Returns:

A StateFeedback object containing the status of the termination operation.

Return type: StateFeedback

Reimplements: Terminate

Function GetSimulationState

SimState simulation_framework::core::SimRunner::GetSimulationState() const override

Retrieves the current state of the simulation.

Returns:

The current simulation state as a SimState enum value.

Return type: SimState

Reimplements: GetSimulationState

Function GetExecutedStepCount

uint64_t simulation_framework::core::SimRunner::GetExecutedStepCount() const override

Retrieves the number of executed simulation steps.

The step counter resets if the simulation is restarted.

Returns:

The number of executed simulation steps.

Return type: uint64_t

Reimplements: GetExecutedStepCount

Function RunOverSimulation

void simulation_framework::core::SimRunner::RunOverSimulation() override

Runs the simulation until it ends without accepting further commands.

Return type: void

Reimplements: RunOverSimulation
