Navigating logs in code

Wiebe

I am looking for the API or code to access log information in a faster than iterative way.

Specifically, I have imported an XES log and want to filter for all events in all traces with a specific value for the concept:name tag, then iterate over this filtered collection of events, and extract information and add information to each of these events, and then export this newly created log.

I have looked over the OpenXES API but so far couldn't find this functionality. Is it possible? The alternative is iterating over the whole log.

Thanks in advance.

Wiebe,

I tried playing around with the XLogInfo and extracting event classes from it based on the concept:name event classifier.
So far I have not succeeded in extracting events that belong to a certain class according to a classifier.

So, as far as I know, iterating through the whole log is the only option at the moment.

As soon as anyone finds another way, let us know!

It is there. I found the solution in the "Log" package, in the following class:

org.processmining.plugins.log.logfilters.LogFilter

You could/should also use the event name classifier, see http://code.deckfour.org/xes/doc/org/deckfour/xes/classification/XEventNameClassifier.html
