Example of analysis code:

public void process(EventHeader event)
{
    // Get reconstructed particle 3Vector's.
    List<Hep3Vector> particles = new ArrayList();
    List<List<ReconstructedParticle>> rpLists = event.get(ReconstructedParticle.class);
    for (List<ReconstructedParticle> collection : rpLists) {
	String name = event.getMetaData(collection).getName();
        if (!name.equals("ReconCheater")) continue;
        for (ReconstructedParticle rp : collection) {
            particles.add(rp.getMomentum());
        }
    }
    // Set up Jet finder.
    double ycut = 0.0005, dycut = 0.0005;
    finder.setYCut(ycut);
    finder.setEvent(particles);
    NJets = finder.njets();

    while (NMJets>MaxNumberJetsExpected) {
        ycut += dycut;
        finder.setYCut(ycut);
        NMJets = finder.njets();
    }
    aida.cloud1D("# jets").fill(NJets);
}
