Detailed Description

A set of ParticleType objects, with defined order.

Allows easy iteration over a set of particles, e.g. to print indices and PDG codes:

B2INFO("index -> PDG code");
const Const::ParticleSet set = Const::chargedStableSet;
//via range-based for
for(const Const::ChargedStable& pdgIter : set) {
  B2INFO(pdgIter.getIndex() << " -> " << pdgIter.getPDGCode());
}
//or, using iterator syntax:
for(Const::ChargedStable pdgIter = set.begin(); pdgIter != set.end(); ++pdgIter) {
  B2INFO(pdgIter.getIndex() << " -> " << pdgIter.getPDGCode());
}

ParticleSets can be created by merging ParticleType objects or other ParticleSets:

Const::ParticleSet set = Const::electron + Const::muon;
Const::ParticleSet set2 = set + Const::photon;

Member Function Documentation

add()

void add

(

const ParticleType &

p

)

Add a copy of the given ParticleType to this set.

If the set already contains the given particle, it remains unchanged.
