| long UTIL::LCStdHepRdr::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)

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)
| IMPL::LCCollectionVec * UTIL::LCStdHepRdr::readEvent | ( | ) |
Read an event and return an LCCollectionVec of MCParticles.

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