Minimalistic discription of a generator-level particle.
The user is expected to use a small filtered collection of particles; the mother indices correspond to positions in this filtered collection.
| int GenParticle::FirstMotherIndex | ( | ) | const |
Returns index of the first mother.
Valid indices start from zero; (-1) indicates that there is no mother in the list. Note that the index correponds to a position in the trimmed list of generator particles, not the orginal genParticles collection in an EDM event.
| int GenParticle::LastMotherIndex | ( | ) | const |
Returns index of the last mother.
See documentation for the method FirstMotherIndex. The returned value is expected to differ from (-1) if only the particle has more than one mother.
| void GenParticle::SetFirstMotherIndex | ( | int | index | ) |
Sets index of the first mother.
The index must follow requirements specified in the documentation of the method FirstMotherIndex.
| void GenParticle::SetLastMotherIndex | ( | int | index | ) |
Sets index of the last mother.
The index must follow requirements specified in the documentation of the method LastMotherIndex.
