TGenerator
Is an abstact base class, that defines the interface of ROOT and the
various event generators. Every event generator should inherit from
TGenerator or its subclasses.
Every class inherited from TGenerator knows already the interface to
the /HEPEVT/ common block. So in the event creation of the various
generators, the /HEPEVT/ common block should be filled
The ImportParticles method then parses the result from the event
generators into a TClonesArray of TParticle objects.
TGenerator(Text_t *name,Text_t *title): TNamed(name,title)
Event generator default constructor
~TGenerator()
Event generator default destructor
TObjArray* ImportParticles(Option_t *option)
Default primary creation method. It reads the /HEPEVT/ common block which
has been filled by the GenerateEvent method. If the event generator does
not use the HEPEVT common block, This routine has to be overloaded by
the subclasses.
The default action is to store only the stable particles (ISTHEP = 1)
This can be demanded explicitly by setting the option = "Final"
If the option = "All", all the particles are stored.
Int_t ImportParticles(TClonesArray *particles, Option_t *option)
Default primary creation method. It reads the /HEPEVT/ common block which
has been filled by the GenerateEvent method. If the event generator does
not use the HEPEVT common block, This routine has to be overloaded by
the subclasses.
The function loops on the generated particles and store them in
the TClonesArray pointed by the argument particles.
The default action is to store only the stable particles (ISTHEP = 1)
This can be demanded explicitly by setting the option = "Final"
If the option = "All", all the particles are stored.
