This class has only one pure virtual 32 // method GeneratePrimaries() which is invoked from G4RunManager 33 // during the event loop. 34 // This class is NOT intended for generating primary vertex/particle 35 // by itself. This class should: 36 // - have one or more G4VPrimaryGenerator concrete classes such as G4ParticleGun 37 // - set/change properties of generator(s) 38 // - pass G4Event object so that the generator(s) can generate primaries. 39 40 // Original author: M.Asai, 1999 41 // -------------------------------------------------------------------- 42 #ifndef G4VUserPrimaryGeneratorAction_hh 43 #define G4VUserPrimaryGeneratorAction_hh 1 44 45 class G4Event; 46 47 class G4VUserPrimaryGeneratorAction 48 { 49 public: 50 G4VUserPrimaryGeneratorAction(); 51 virtual ~G4VUserPrimaryGeneratorAction() = default; 52 53 virtual void GeneratePrimaries(G4Event* anEvent) = 0; 54 }; 55 56 #endif 57
