public class SimulatorSequencer
extends AbstractSequencer
implements Initializable

This class is used as a Sequencing instanance for simulating the target load on STELLA. Consider the following points.

• Put the master mind in simulator mode by setting the MasterMind.KEY_SIMULATE key to true.
• Use thw SimulatorSequencer as the sequencer in the master mind, key MasterMind.KEY_SEQUENCER.
• Normally, you will assign a local weather station to the master mind and thus to the error handler that simulates the weather. The MasterMind.KEY_LOCALWEATHER key should point to a SimulatorWeather instance.
• Make sure that the time in the parameter cluster is advancable, i.e. of SettableTime type.
• The error handler can remain unchanged.

Constructor Detail

SimulatorSequencer

public SimulatorSequencer(Map prop)

Construct a new sequencer for load simulation.

Method Detail

init

public void init()

Creates two maps that link target names to trigger names. The first map, constructed from KEY_TRUE consists of target names that spark setting of the indicated triggers to true, as soon as the target run()s. The second map sets triggers to false.

Specified by:

init in interface Initializable

Overrides:

init in class CastingContainer

getStepsForTarget

public List getStepsForTarget(TargetDefinition target)

We don't need any steps for any sequence, but returning an empty list here would refrain the sequencer from being executed. Thus we return a singleton list here with a dummy entry. Additionally, we keep a reference to the target to allow calculation of expected observing time.

Specified by:

getStepsForTarget in interface Sequencing

load

public void load(List dom)

Ignore.

Specified by:

load in interface Sequencing

abort

public void abort(List dom)

Ignore.

Specified by:

abort in interface Sequencing

append

public void append(List dom)

Ignore.

Specified by:

append in interface Sequencing

prepend

public void prepend(List dom)

Ignore.

Specified by:

prepend in interface Sequencing

registerGlobals

public void registerGlobals(GlobalGrouping globals)

Needed for the time parameter.

Specified by:

registerGlobals in interface GlobalDepending

registerRender

public void registerRender(CommandRendering chef)

Not needed.

Specified by:

registerRender in interface Sequencing

registerLauncher

public void registerLauncher(CommandLaunching[] launch)

Not needed.

Specified by:

registerLauncher in interface Sequencing

start

public Thread start()

In principle, we simply advance the time for the calculated observing time. If the time parameter is not advancable, we wait for the observing time.

Specified by:

start in interface Sequencing

Returns:

The thread that has just been started

run

public void run()

Advances the time for the calculated observing time of the target or wait for this period.

Specified by:

run in interface Runnable

getAsociatedThread

public Thread getAsociatedThread()

Returns the thread the sequencer is running in. If the sequencer is not running, i.e. the sequencer's thread is not alive, this method returns null.

Specified by:

getAsociatedThread in interface CancelRunnable

maxTimeToCancel

public long maxTimeToCancel()

Maximum timer-out used on shut-down. We do not do a specific thread, thus return zero here.

Specified by:

maxTimeToCancel in interface CancelRunnable

cancel

public void cancel()

Does nothing.

Specified by:

cancel in interface CancelRunnable

forward

public void forward(ReplyEvent rp)

Ignore.

Specified by:

forward in interface ReplySubscriber

isCancel

public boolean isCancel()

Return false;

Specified by:

isCancel in interface Sequencing
