Detailed Description

This class converts the Events into HepMC::GenEvents.

The output is depended on the HepMC version HEJ is compiled with, both HepMC 2 and HepMC 3 are supported. If HEJ 2 is compiled without HepMC calling this interface will throw an error.

This interface will also keep track of the cross section of all the events that being fed into it.

init_event()

HepMC::GenEvent HEJ::HepMC2Interface::init_event ( Event const &  event ) const

protected

initialise generic event infomrations (not central weights)

Parameters

event

Event to convert

operator()()

HepMC::GenEvent HEJ::HepMC2Interface::operator()	(	Event const &	event,
		int	weight_index = -1
	)

main function to convert an event into HepMC::GenEvent

Parameters

event	Event to convert
weight_index	optional selection of specific weight (negative value gives central weight)

set_central()

void HEJ::HepMC2Interface::set_central	(	HepMC::GenEvent &	out_ev,
		Event const &	event,
		int	weight_index = -1
	)

Sets the central value from event to out_ev.

Parameters

out_ev	HepMC::GenEvent to write to
event	Event to convert
weight_index	optional selection of specific weight (negative value gives "central")

This overwrites the central value of out_ev.
