Constructor Detail

StateController

protected StateController(Configuration configuration)

Creates a new instance of this class using the given parameter.

Parameters:

configuration - The configuration which will be used to initialize the controller.

Method Detail

init

protected final void init()

Description copied from class: AbstractController

This method should to the initialization work.

Specified by:

init in class AbstractController

cleanup

protected final void cleanup()

Description copied from class: AbstractController

This method should clean up.

Specified by:

cleanup in class AbstractController

toString

public final java.lang.String toString()

Specified by:

toString in class AbstractController

terminateMonitoring

public final boolean terminateMonitoring()

Permanently terminates monitoring.

Specified by:

terminateMonitoring in interface IStateController

Returns:

true if now terminated; false if already terminated

See Also:

IStateController.isMonitoringTerminated()

isMonitoringTerminated

public final boolean isMonitoringTerminated()

Description copied from interface: IStateController

Returns whether monitoring is permanently terminated.

Specified by:

isMonitoringTerminated in interface IStateController

Returns:

true if monitoring is permanently terminated, false if monitoring is enabled or disabled.

See Also:

IStateController.terminateMonitoring()

enableMonitoring

public final boolean enableMonitoring()

Enables monitoring.

Specified by:

enableMonitoring in interface IStateController

Returns:

true if monitoring is enabled, false otherwise

disableMonitoring

public final boolean disableMonitoring()

Disables monitoring. If monitoring is disabled, the MonitoringController simply pauses. Furthermore, probes should stop collecting new data and monitoring writers stop should stop writing existing data.

Specified by:

disableMonitoring in interface IStateController

Returns:

true if monitoring is disabled, false otherwise

isMonitoringEnabled

public final boolean isMonitoringEnabled()

Description copied from interface: IStateController

Returns whether monitoring is enabled or disabled/terminated.

Specified by:

isMonitoringEnabled in interface IStateController

Returns:

true of monitoring is enabled, false if monitoring is disabled or terminated.

See Also:

IStateController.disableMonitoring(), IStateController.enableMonitoring()

getName

public final java.lang.String getName()

Description copied from interface: IStateController

Returns the name of this controller.

Specified by:

getName in interface IStateController

Returns:

String

getHostname

public final java.lang.String getHostname()

Description copied from interface: IStateController

The hostname will be part of the monitoring data and allows to distinguish observations in cases where the software system is deployed on more than one host. When you want to distinguish multiple Virtual Machines on one host, you* have to set the hostname manually in the Configuration.

Specified by:

getHostname in interface IStateController

Returns:

The hostname.

incExperimentId

public final int incExperimentId()

Increments the experiment ID by 1 and returns the new value.

Specified by:

incExperimentId in interface IStateController

Returns:

experimentID

setExperimentId

public final void setExperimentId(int newExperimentID)

Sets the experiment ID to the given value.

Specified by:

setExperimentId in interface IStateController

Parameters:

newExperimentID - The new ID.

getExperimentId

public final int getExperimentId()

Specified by:

getExperimentId in interface IStateController

Returns:

The experiment ID.

isDebug

public final boolean isDebug()

Description copied from interface: IStateController

Is the debug mode enabled?

Debug mode is for internal use only and changes a few internal id generation mechanisms to enable easier debugging. Additionally, it is possible to enable debug logging in the settings of the used logger.

Specified by:

isDebug in interface IStateController

Returns:

debug mode

setStateListener

public void setStateListener(IStateListener stateListener)
