// Class description:
|
|
//
|
|
// This class represents a primary particle.
|
|
// G4PrimaryParticle is a completely different object from G4Track or
|
|
// G4DynamicParticle. G4PrimaryParticle is designed to take into account
|
|
// the possibility of making the object persistent, i.e. kept with G4Event
|
|
// class object within an ODBMS. This class is therefore almost independent
|
|
// from any other Geant4 object. The only exception is a pointer to
|
|
// G4ParticleDefinition, which can be rebuilt by its PDGcode.
|
|
//
|
|
// Primary particles are stored in G4PrimaryVertex through a form of linked
|
|
// list. A G4PrimaryParticle object can have one or more objects of this
|
|
// class as its daughters as a form of linked list.
|
|
// A primary particle represented by this class object needs not to be
|
|
// a particle type which Geant4 can simulate:
|
|
// Case a) mother particle is not a particle Geant4 can simulate
|
|
// daughters associated to the mother will be examined.
|
|
// Case b) mother particle is a perticle Geant4 can simulate
|
|
// daughters associated to the mother will be converted to
|
|
// G4DynamicParticle and be set to the mother G4Track.
|
|
// For this case, daugthers are used as the "pre-fixed"
|
|
// decay channel.
