com.anylogic.engine.Experiment<ROOT>

Type Parameters:: ROOT - class of top-level agent

All Implemented Interfaces:: AgentConstants, EnvironmentConstants, UtilitiesMath, UtilitiesRandom, UtilitiesString, Serializable

Direct Known Subclasses:: ExperimentRunFast, ExperimentSimulation

public abstract class Experiment<ROOT extends Agent>
extends Utilities

A base class for all AnyLogic experiments. Experiment describes how would one like to run the model (just perform a single simulation run, do Monte Carlo simulation, vary parameters, optimize, etc.), and what outputs of the model you are interested in (this may be a simple chart of how a certain value was changing over time during a run, or how an observable depends on a parameter in case of multiple runs, or a histogram in case of risk analysis, etc.). The experiment is also capable of storing the outputs producted by the model so that they are available after the simulation and independently of it. Experiment can display itself in a presentation window and be controlled by the presentation GUI. For that purpose it supports a set of commands that can be assigned to the presentation window toolbar buttons and menu items.

AnyLogic models with GUI can run as Java applications.

Returns:: the name (window title) of the experiment

error

public RuntimeException error(Throwable cause,
 String errorText)

Description copied from class: Utilities

Signals an error during the model run by throwing a RuntimeException with errorText preceded by the agent full name.

Specified by:: error in class Utilities
Parameters:: cause - the cause (which will be saved for more detailed message), may be null; errorText - the text describing the error that will be displayed.
Returns:: actually this method never returns, it throws runtime exception by itself.
But the return type is defined for some cases when you would like to use the following form of call: throw error("my message");

errorInModel

public RuntimeException errorInModel(Throwable cause,
 String errorText)

Description copied from class: Utilities

Signals an model logic error during the model run by throwing a ModelException with errorText preceded by the agent full name.
This method differs from error() in the way of displaying error message: model logic errors are 'softer' than other errors, they use to happen in the models and signal the modeler that model might need some parameters adjustments. Examples are 'entity was unable to leave flowchart block because subsequent block was busy', 'insufficient capacity of pallet rack' etc.

Specified by:: errorInModel in class Utilities
Parameters:: cause - the cause (which will be saved for more detailed message), may be null; errorText - the text describing the error that will be displayed.
Returns:: actually this method never returns, it throws runtime exception by itself.
But the return type is defined for some cases when you would like to use the following form of call: throw errorInModel("my message");

warning

public void warning(String warningText)

Description copied from class: Utilities

Signals a warning during the model run with warningText preceded by the agent full name.
Warnings may be turned off in the AnyLogic preferences (runtime section) or by API: AnyLogicRuntimePreferences.setEnableWarnings(Boolean).
This method checks against numerous warnings output:

In case of multiple warnings having equal warningText, only the first 10 of them are displayed.
When more than 1000 warnings having different warningText occur, all the subsequent warnings (including new occurrences of those in the first 1000) will stop displaying.
Be careful with using dynamically changing warningText (e.g. listing names of agents), it could be better to use Utilities.warning(String, Object...).

Specified by:: warning in class Utilities
Parameters:: warningText - the text describing the warning that will be displayed.

warning

public void warning(String warningTextFormat,
 Object... args)

Description copied from class: Utilities

Signals a warning during the model run with warningText preceded by the agent full name. The method allows warning format syntax like in String.format(String, Object...) method.
Warnings may be turned off in the AnyLogic preferences (runtime section) or by API: AnyLogicRuntimePreferences.setEnableWarnings(Boolean).
This method checks against numerous warnings output:

In case of multiple warnings having equal warningTextFormat, only the first 10 of them are displayed.
It is safe to raise numerous warnings with equal format string (which defines the warning type) but varying args - AnyLogic will take care to display only 10 first warnings of each warning type.
When more than 1000 warnings having different warningTextFormat occur, all the subsequent warnings (including new occurrences of those in the first 1000) will stop displaying.
Don't use dynamically changing warningTextFormat (e.g. listing names of agents), use args instead.

Is called in static main() method of applications, after the experiment is constructed. Is intended to perform initial setup of the simulation engine and the presentation, if any. This is a user's extension points; by default does nothing.

Parameters:: experimentHost - experiment host, see ExperimentHost

setupEngine

@AnyLogicInternalCodegenAPI
public void setupEngine(Engine engine)

Is called for the simulation engine when it is created

Parameters:: engine - the simulation engine

onDestroy

@AnyLogicInternalCodegenAPI
public void onDestroy()

User extension point which is called when the experiment object is dynamically disposed - before closing the model window.
This method may be overridden to perform custom actions.
Default implementation does nothing.

onDestroy_xjal

@AnyLogicInternalCodegenAPI
public void onDestroy_xjal()

This method normally shouldn't be called by user.
Is called when the experiment object is dynamically disposed - before closing the model window.
This method should be overridden to release resources (e.g. commit connections with database) and call super.doDestroy_xjal() method at the end. Don't call onDestroy() when overriding this method: it is called automatically

destroy_xjal

@AnyLogicInternalAPI
public final void destroy_xjal()

This method normally shouldn't be called by user.
Is called when the experiment object is dynamically disposed - before closing the model window.

initDefaultRandomNumberGenerator

@AnyLogicInternalCodegenAPI
public void initDefaultRandomNumberGenerator(Engine engine)

This method should be overridden to initialize random number generator of the given engine
Default implementation set new random generation with random seed - for unique experiments

Parameters:: engine - the engine instance

onError

public void onError(Throwable error)

This method may be overridden to perform custom processing on errors in the model execution (i.e. errors in the action code of events, dynamic events, transitions, entry/exit codes of states etc, formulas, conditions of events etc.)
By default, this method does nothing.
This method shouldn't be called directly by user. Instead, engine calls it internally.

Parameters:: error - an error which has occurred during event execution

onError

public void onError(Throwable error,
 Agent root)

This method may be overridden to perform custom processing on errors in the model execution (i.e. errors in the action code of events, dynamic events, transitions, entry/exit codes of states etc, formulas, conditions of events etc.)
By default, this method does nothing.
This method shouldn't be called directly by user. Instead, engine calls it internally.

Parameters:: error - an error which has occurred during event execution; root - the root (main) agent of the model, useful for experiments with multiple runs executed in parallel. May be null in some cases (e.g. on errors during root agent creation).
Since:: 8.4

addExecutionListener

@AnyLogicInternalAPI
public final void addExecutionListener(ExperimentExecutionListener listener)

This method is internal and shouldn't be called by user.
it may be removed/renamed in future.

removeExecutionListener

@AnyLogicInternalAPI
public final void removeExecutionListener(ExperimentExecutionListener listener)

This method is internal and shouldn't be called by user.
it may be removed/renamed in future.

setCommandLineArguments_xjal

@AnyLogicInternalCodegenAPI
public void setCommandLineArguments_xjal(String[] commandLineArguments)

This method should not be called by user

Parameters:: commandLineArguments -

getMutexRead_xjal

@AnyLogicInternalAPI
public Object getMutexRead_xjal()

This field shouldn't be called by user
is public due to technical reasons

getMutexWrite_xjal

@AnyLogicInternalAPI
public Object getMutexWrite_xjal()

This field shouldn't be called by user
is public due to technical reasons

registerExperimentHost_xjal

@AnyLogicInternalAPI
public void registerExperimentHost_xjal(IExperimentHost experimentHost)

This method isn't designed to be called by user.
Public due to technical reasons
May be removed in future releases
