Writing the Drivers in Jython

The case for Jython

Let's consider the following case: You are an experienced org.lcsim user and have a range of Drivers that perform various tasks for you. You would like a summer student to help you with some coding, but the student has no programming experience whatsoever.
Rather than having to waste two weeks teaching the details of the Java language, you could create an Example in Jython, an object-oriented scripting language that can be learned in a few days.

The Jython wrapper

If you want to use Drivers written in Jython, you will have to use a little wrapper script. That should not be much of a hassle, since your program is likely split up into various Drivers already anyway. (If not, it probably should be). In this case, all you have to do is replace your current Java wrapper with the Jython version.
Please load mainLoop.py into Jas3

Using the Jython wrapper

Please save mainLoop.py, Analysis101.java, Analysis102.py and psiMuMu.slcio to your harddisk. psiMuMu.slcio is a small datasample, Analysis101.java is our analysis module, which is taken straight from the JAS3 examples, Analysis102.py is a slightly modified Jython version of the Java module and mainLoop.py is the wrapper that takes care of loading the analysis module correctly.
After compiling the java file with

javac Analysis101.java

you can start the program with

jython mainLoop.py

which will loop over the data sample and create a file exampleAnalysis.aida. Please note that this file contains both the output from the Java module and the output from the Jython module.

loop.add(Analysis101())
loop.add(Analysis102())
