This little tutorial will help you build your own analysis code step-by-step. After finishing this section you should be able to write a complete analysis inside the JAS3 framework.
Let's get started: Create a new file with File->New->Java File. Save it as MyExampleClass.java.
At first we need to create a class that inherits from the Driver class:
...
| Code Block |
|---|
import java.util.List;
import org.lcsim.event.EventHeader;
import org.lcsim.event.MCParticle;
import org.lcsim.util.Driver;
import org.lcsim.util.aida.AIDA;
public class MyExampleClass extends Driver {
private AIDA aida = AIDA.defaultInstance();
public MyExampleClass(){
add(new MyJetFindingDriver());
add(new Analysis101());
};
public void process(EventHeader event) {
super.process(event); // this takes care that the child Drivers are loaded and processed.
List<List<MCParticle>> jetList = (List<List<MCParticle>>) event.get("jetList");
aida.cloud1D("nJets").fill(jetList.size());
}
}
|
Save the file.
Open the file !MyJetFindingDriver.java! and compile it.
Open the Analysis101 example and compile it.
Compile and load the MyExampleClass example.
