GLMStimulatorWorker
public class GLMStimulatorWorker extends ServletWorker (Code)
 One created for every URL access.
 If either waitBefore or waitAfter is true, uses a blackboard
 service, a watcher, and a trigger to monitor published tasks to see
 when they are complete.

Field Detail
batchesSent
protected int batchesSent(Code)
batches sent so far



debug
protected boolean debug(Code)
dump debug output if true



forPrep
protected String forPrep(Code)
option override of task FOR preposition



inputFile
protected String inputFile(Code)



interval
protected long interval(Code)
millis between batches



nextSendTime
protected long nextSendTime(Code)
when was the last batch sent



rescindAfterComplete
protected boolean rescindAfterComplete(Code)
remove the injected tasks after they have been completed



rescindTasks
protected Set rescindTasks(Code)



responseData
protected GLMStimulatorResponseData responseData(Code)
returned response



sentTasks
protected Map sentTasks(Code)
Collection of tasks that have been sent. Needed for later rescinds



support
protected BlackboardServletSupport support(Code)



taskParserClass
protected String taskParserClass(Code)



tasksPerBatch
protected int tasksPerBatch(Code)
tasks per batch



testStart
protected long testStart(Code)
start of the whole test



tm
protected TriggerModel tm(Code)
for waiting for a subscription on the blackboard



totalBatches
protected int totalBatches(Code)
total batches requested



useConfidence
protected boolean useConfidence(Code)
use confidence to determine when task is complete



waitAfter
protected boolean waitAfter(Code)
wait for completion after publishing everything



waitBefore
protected boolean waitBefore(Code)
wait for completion before publishing next batch



watcher
protected SubscriptionWatcher watcher(Code)
for waiting for a subscription on the blackboard





Method Detail
blackboardChanged
protected void blackboardChanged()(Code)
Called when one of the tasks that was added to the blackboard has it's plan element change. If the task has been successfully disposed, it is removed from the sentTasks Map.



execute
public void execute(HttpServletRequest request, HttpServletResponse response, SimpleServletSupport support) throws IOException, ServletException(Code)
 Here is our inner class that will handle all HTTP and
 HTTPS service requests.
 If we should wait until the batch is complete, we make a watcher to watch
 the blackboard, a trigger that will call blackboardChanged (), and a trigger model
 to connect them.
 

See Also:   GLMStimulatorWorker.blackboardChanged



getElapsedTime
protected String getElapsedTime(long diff)(Code)
encodes a time interval in a min:sec:millis format



getPrefix
protected String getPrefix()(Code)



getResult
protected XMLable getResult()(Code)
Main work done here.

Sends the first batch of tasks, and keeps sending until totalBatches have been sent. If should wait for completion, waits until notified by blackboardChanged ().

Will wait interval milliseconds between batches if there are more than one batches to send.
See Also:   GLMStimulatorWorker.getSettings
See Also:   GLMStimulatorWorker.blackboardChanged an "XMLable" result.




getSettings
public void getSettings(String name, String value)(Code)
 Use a query parameter to set a field
 Sets the recognized parameters : inputFile, debug, totalBatches, tasksPerBatch, interval, and wait
 



printTestingSummary
protected void printTestingSummary()(Code)
record the elapsed time



readXmlTasks
protected Collection readXmlTasks(String xmlTaskFile)(Code)
Parse the xml file and return the COUGAAR tasks.
Parameters:
  xmlTaskFile - file defining tasks to stimulate cluster with Collection of tasks defined in xml file



recordTime
protected void recordTime(String taskUID, Date sentTime)(Code)
records the time taken for the task



sendNextBatch
protected void sendNextBatch(boolean withinTransaction)(Code)
Publishes the tasks created by readXmlTasks.

For each task, adds to sentTasks map of task to its send time. sentTasks is used later by blackboardChanged to determine how long the task took to complete.
See Also:   GLMStimulatorWorker.readXmlTasks
See Also:   GLMStimulatorWorker.blackboardChanged
Parameters:
  withinTransaction - - true when called from handleSuccessfulPlanElementthis avoids having nested transactions




setSchedulerService
final public void setSchedulerService(SchedulerService ss)(Code)
