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

◆ Embed()

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

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

Definition at line 500 of file HepMCNodeReader.cc.

◆ enable_position_filter()

void HepMCNodeReader::enable_position_filter	(	const double	x_min,
		const double	x_max,
		const double	y_min,
		const double	y_max,
		const double	z_min,
		const double	z_max
	)

Enable and define a position filter. The x,y,z limits are in cm.

Definition at line 446 of file HepMCNodeReader.cc.

◆ Init()

int HepMCNodeReader::Init ( PHCompositeNode * )

virtual

Called during initialization, i.e. registered via Fun4AllServer::registerSubsystem(). 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.

◆ process_event()

int HepMCNodeReader::process_event ( PHCompositeNode * )

virtual

Called for each event. This is where you do the real work.

void HepMCNodeReader::SetT0 ( const double t0 )

inline

Arbitary time shift for all sub-events. And the vertex shifts are better controlled for individually HEPMC subevents in Fun4AllHepMCInputManagers and event generators.

◆ SmearVertex()

void HepMCNodeReader::SmearVertex	(	const double	s_x,
		const double	s_y,
		const double	s_z

◆ VertexPosition()

void HepMCNodeReader::VertexPosition	(	const double	v_x,
		const double	v_y,
