Member Typedef Documentation

using ActsExamples::EventStore::BarcodeWithoutSubparticle = Acts::MultiIndex<uint64_t, 16, 16, 16, 16>

Store subparticle count for {primVertex, secVertex, part, gen} This is done using a pseudo-barcode that contains all fields but not the subparticle counter. This can be used as key in a map to store the subparticle information

using ActsExamples::EventStore::ParticleContainer = std::set<ActsFatras::Particle, ActsExamples::detail::CompareParticleId>

Use a std::set here because it allows for fast insertion and ensures uniqueness. Thus particle collisions are detected early.
