Detailed Description

HepMCNodeReader take input from all subevents from PHHepMCGenEventMap and send them to simulation in Geant4 For HepMC subevent which is already simulated, they will not be simulated again in Geant4.

Member Function Documentation

void HepMCNodeReader::Embed ( const int i = 1 )

this function is depreciated. Embedding IDs are controlled for individually HEPMC subevents in Fun4AllHepMCInputManagers and event generators.

Here is the caller graph for this function:

int HepMCNodeReader::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.
