36 // This is the abstract base class of the user's mandatory action class
37 // for primary vertex/particle generation. This class has only one pure
38 // virtual method GeneratePrimaries() which is invoked from G4RunManager
39 // during the event loop.
40 // Note that this class is NOT intended for generating primary vertex/particle
41 // by itself. This class should
42 // - have one or more G4VPrimaryGenerator concrete classes such as G4ParticleGun
43 // - set/change properties of generator(s)
44 // - pass G4Event object so that the generator(s) can generate primaries.
