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.

Member Function Documentation

add_variation()

void HEJ::HepMCInterface::add_variation	(	HepMC::GenEvent &	out_ev,
		std::vector< EventParameters > const &	variations
	)

Add the event variations to out_ev.

init_kinematics()

HepMC::GenEvent HEJ::HepMCInterface::init_kinematics

(

Event const &

event

)

initialise the event kinematics (everything but the weights)

Parameters

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

operator()()

HepMC::GenEvent HEJ::HepMCInterface::operator()	(	Event const &	event,
		ssize_t	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::HepMCInterface::set_central	(	HepMC::GenEvent &	out_ev,
		Event const &	event,
		ssize_t	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")
