Member Function Documentation

long UTIL::LCStdHepRdrNew::getNumberOfEvents ( ) const

inline

Get number of events in the stdhep file.

This number is read from the file header (no guarantee that it is correct)

Definition at line 45 of file LCStdHepRdrNew.h.

References _reader, and UTIL::lStdHep::numEvents().

long UTIL::LCStdHepRdrNew::getNumberOfTotalEventsExpected ( ) const

inline

Get total number of expected events in the whole set of stdhep files from which this stdhep file belongs to.

This number is read from the file header (no guarantee that it is correct)

Definition at line 53 of file LCStdHepRdrNew.h.

void UTIL::LCStdHepRdrNew::printHeader

(

std::ostream &

os = std::cout

)

Print the file header to the given ostream.

Definition at line 40 of file LCStdHepRdrNew.cc.

IMPL::LCCollectionVec * UTIL::LCStdHepRdrNew::readEvent

(

)

Read an event and return an LCCollectionVec of MCParticles.

Deprecated:

please use updateEvent()

int UTIL::LCStdHepRdrNew::threeCharge

(

int

pdgID

)

const

Return the charge of the particle times 3 - code copied from HepPDT package.

PID digits (base 10) are: n nr nl nq1 nq2 nq3 nj The location enum provides a convenient index into the PID.

void UTIL::LCStdHepRdrNew::updateNextEvent	(	IMPL::LCEventImpl *	evt,
		const char *	colName = EVENT::LCIO::MCPARTICLE
	)

Reads the next stdhep event and adds a new MCParticle collection to the the event with default name 'MCParticle'.

Exceptions

IO::EndOfDataException

if no event in stdhep file
