45 // CHANGE HISTORY
46 // --------------
47 // 26/10/2004, F Lei
48 // Added the Multiple_vertex capability.
49 // Removed "inline" from all Set/Get methods.
50 //
51 // Version 2.0, 05/02/2004, Fan Lei, Created.
52 // based on version 1.1 in Geant4 v6.0
53 // - Mutilple particle source definition
54 // - Re-structured commands
55 // - Split the task into smaller classes
56 //
57 // - old commonds have been retained for backward compatibility, but will
58 // be removed in the future.
59 //
61 //
62 // Class Description:
63 //
64 // The General Particle Source is designed to replace the G4ParticleGun class.
65 // It is designed to allow specification of mutiple particle sources, each with
66 // independent definitions of particle type, position, direction (or angular)
67 // and energy distributions.
68 //
