Method Details

processModel

public abstract ProcessingResult processModel(ProcessingContext context,
 T instance,
 Date epoch)

Processes simulation events for a real-time digital twin.

Parameters:

context - the processing context.

instance - the digital twin instance.

epoch - the current time of the simulation.

Returns:

ProcessingResult.UpdateDigitalTwin to update the digital twin, or ProcessingResult.NoUpdate to ignore the changes.

onInitSimulation

public ProcessingResult onInitSimulation(InitSimulationContext context,
 T instance,
 Date epoch)

Optional method that is called per-instance when a simulation is started. Default behavior is a no-op.

onInitSimulation can be used when internal digital twin starting state is set outside the context of a digital twins init method and may be changed between simulation runs.

• Set variables in global or shared data.
• Run a simulation.
• onInitSimulation is called (per-instance) and digital twin instances set internal state based on the values in shared data.
• Complete simulation and evaluate the result.

Parameters:

context - The simulation init context.

instance - The digital twin instance.

epoch - the simulation start time.

Returns:

ProcessingResult.UpdateDigitalTwin or ProcessingResult.NoUpdate. Default behavior: ProcessingResult.NoUpdate.
