|
|
// This is a class which represents a primary particle.
|
|
// This is completely deferent class from G4Track or G4DynamicParticle.
|
|
// This class is designed with taking into account the possibility of
|
|
// making this class persistent, i.e. kept with G4Event class object
|
|
// to ODBMS. Thus this class is almost free from any other Geant4 classes.
|
|
// The only exception is a pointer to G4ParticleDefinition but it can be
|
|
// rebuilt by the PDGcode.
|
|
//
|
|
// Primary particles are stored in G4PrimaryVertex object with a form
|
|
// of linked list. Also, an object of this PrimaryParticle class can have
|
|
// one or more objects of this class as its daughters with a form of
|
|
// linked list.
|
|
// A parimary particle represented by this class object needs not to be
|
|
// a particle of 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 G4Dynamic
|
|
// particle and be set to the mother G4Track. For this case, dauthers
|
|
// are used as the "pre-fixed" decay channel.
