44 // class description:
45 //
46 // This is a class which represents a primary particle.
47 // This is completely deferent class from G4Track or G4DynamicParticle.
48 // This class is designed with taking into account the possibility of
49 // making this class persistent, i.e. kept with G4Event class object
50 // to ODBMS. Thus this class is almost free from any other Geant4 classes.
51 // The only exception is a pointer to G4ParticleDefinition but it can be
52 // rebuilt by the PDGcode.
53 //
54 // Primary particles are stored in G4PrimaryVertex object with a form
55 // of linked list. Also, an object of this PrimaryParticle class can have
56 // one or more objects of this class as its daughters with a form of
57 // linked list.
58 // A parimary particle represented by this class object needs not to be
59 // a particle of type which Geant4 can simulate.
60 // case a) mother particle is not a particle Geant4 can simulate
61 // daughters associated to the mother will be examined.
62 // case b) mother particle is a perticle Geant4 can simulate
63 // daughters associated to the mother will be converted to G4Dynamic
64 // particle and be set to the mother G4Track. For this case, dauthers
65 // are used as the "pre-fixed" decay channel.
