Detailed Description

Generic Wrapper for the fortran HEPEVT common block.

This class is intended for static use only - it makes no sense to instantiate it.

bool HepMC::HEPEVT_Wrapper::check_hepevt_consistency ( std::ostream & ostr = std::cout )

static

check for problems with HEPEVT common block

This method inspects the HEPEVT common block and looks for inconsistencies in the mother/daughter pointers

Definition at line 88 of file HEPEVT_Wrapper.cc.

References event_number(), first_child(), first_parent(), last_child(), last_parent(), m(), number_entries(), print_hepevt_particle(), and print_legend().

void HepMC::HEPEVT_Wrapper::print_hepevt ( std::ostream & ostr = std::cout )

static

write information from HEPEVT common block

dumps the content of this HEPEVT event to ostr (Width is 80)

void HepMC::HEPEVT_Wrapper::print_hepevt_particle	(	int	index,
		std::ostream &	ostr = `std::cout`
	)

static

write particle information to ostr

dumps the content HEPEVT particle entry i (Width is 120) here i is the C array index (i.e. it starts at 0 ... whereas the fortran array index starts at 1) So if there's 100 particles, the last valid index is 100-1=99
