Detailed Description

JetHepMCLoader loads special jet objects encoded in HepMC records to DST Jet nodes. Example use are loading sHijing HIJFRG jets.

Example use for readback HIJFRAG truth jets from the sHijing HepMC records:

JetHepMCLoader * hepmcjet = new JetHepMCLoader("sHijing_HIJFRG");
hepmcjet->saveQAPlots();
hepmcjet->addJet("AntiKt_sHijing_HIJFRG_r02",0,Jet::ANTIKT,0.2,2000000,103);
hepmcjet->addJet("AntiKt_sHijing_HIJFRG_r04",0,Jet::ANTIKT,0.4,4000000,103);
hepmcjet->addJet("AntiKt_sHijing_HIJFRG_r06",0,Jet::ANTIKT,0.6,6000000,103);
se->registerSubsystem(hepmcjet);

Here is the caller graph for this function:

int JetHepMCLoader::Init ( PHCompositeNode * )

overridevirtual

Called during initialization. Typically this is where you can book histograms, and e.g. register them to Fun4AllServer (so they can be output to file using Fun4AllServer::dumpHistos() method).

Reimplemented from SubsysReco.

int JetHepMCLoader::InitRun ( PHCompositeNode * )

overridevirtual

Called for first event when run number is known. Typically this is where you may want to fetch data from database, because you know the run number.
