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