no read XEvent

benfy85

Hi all,

I have a new problem.. 

I used this code to find the name of the event XEvent, I just do not return the name of the event, I do not return anything.
What is wrong?

Thank you!

for(XEvent event:trace2) {

try {

XExtendedEvent extendedEvent2 = XExtendedEvent.wrap(event); 

String eventName2 = extendedEvent2.getName();

Date timestamp2 = extendedEvent2.getTimestamp();

     }catch (Exception e) { 

System.out.printf("Error into trace 2");

      }

}

Hi Benfy85,

I wonder what sort of "name" that you'd like to extract from an XEvent object. If you'd like to extract an event class/timestamp of an XEvent object from a log, what I typically do is write the following code:

XLog log; // this is given

XTrace trace; // this is also given

XTimeExtension extractor = XTimeExtension.instance(); // utility object to extract timestamp

XLogInfoImpl logInfo = XLogInfoFactory.createLogInfo(log);

XEventClasses eventClasses = logInfo.getEventClasses();

for (XEvent event : trace){

  // extracting the name of the event class of the event

  eventClasses.getClassOf(event).toString();

  // extracting its timestamp

  Date timestamp = extractor.extractTimestamp(event);

}

I hope it helps,

Regards,

Arya

Thank you,  I have been very helpful for your help.

The eventName that I mean into "file.MXML" corrisponds to

<WorkflowModelElement>eventName</WorkflowModelElement> 

and in this code return return the string "eventName+record".
that corrisponds to 

<WorkflowModelElement>eventName</WorkflowModelElement>

<EventType unknowntype="record">unknown</EventType>

How can I get only the eventName?

Thank you

I found how to solve the problem, I used this code:

int q=0;

for(XEvent event:trace2) {
eventName1 = XConceptExtension.instance().extractName(trace2.get(q));

q++;

}
You have unlocked me.
Thank you,

Hi Erika,

Why don't you do it like this?

for(XEvent event:trace2) {
String eventName1 = XConceptExtension.instance().extractName(event);

}

I do not see the need/use for the q index since in the for loop you already extract the events from the trace.

You are right! 

I have not thought, because I used this code to get the track by:
XConceptExtension.instance () extractName (log.get(t)).

But  you have solved  another problem that came out during the execution.

Thank you,  

Erika
