Class ParametricAnalysisRunner

java.lang.Object

common.controller.ParametricAnalysisRunner

All Implemented Interfaces:

AbortMeasure

public class ParametricAnalysisRunner
extends Object
implements AbortMeasure

Title: ParametricAnalysisRunner

Description: Runs every step of a What-If (parametric analysis) simulation and aggregates the per-step results into a single PAResultsModel.

This class contains no Swing code and shows nothing on screen, so a What-If analysis can be driven from a headless context - the command line, a test harness, or a CI job. PADispatcherThread wraps it to supply the progress window and the results window; everything those two share lives here, so a fix to the step loop reaches both callers.

Constructor Details

ParametricAnalysisRunner

public ParametricAnalysisRunner(SimulationDefinition simd,
 ParametricAnalysisRunner.Listener listener)

Parameters:

simd - the simulation definition carrying the parametric analysis model

listener - progress callback, or null for a silent run

Method Details

run

public PAResultsModel run()

Runs every step of the parametric analysis and blocks until all of them have finished. The model's original values are restored before returning.

Returns:

the aggregated results, or null if no step produced any measure

isStopped

public boolean isStopped()

Returns:

true if the run was ended early by stopRun()

pause

public void pause()

Pauses every step currently running.

stopRun

public void stopRun()

Stops the run, aborting the measures of every step still in flight, and blocks until the results of the steps that did finish have been collected.

restart

public void restart()

Restarts every paused step.

abortMeasure

public void abortMeasure(int index)

Aborts a measure across every running step.

Specified by:

abortMeasure in interface AbortMeasure

Parameters:

index - index of the measure to be aborted
