// CHANGE HISTORY
|
|
// --------------
|
|
// 26/10/2004, F Lei
|
|
// Added the Multiple_vertex capability.
|
|
// Removed "inline" from all Set/Get methods.
|
|
//
|
|
// Version 2.0, 05/02/2004, Fan Lei, Created.
|
|
// based on version 1.1 in Geant4 v6.0
|
|
// - Mutilple particle source definition
|
|
// - Re-structured commands
|
|
// - Split the task into smaller classes
|
|
//
|
|
// - old commonds have been retained for backward compatibility, but will
|
|
// be removed in the future.

// Class Description:
|
|
//
|
|
// The General Particle Source is designed to replace the G4ParticleGun class.
|
|
// It is designed to allow specification of mutiple particle sources, each with
|
|
// independent definitions of particle type, position, direction (or angular)
|
|
// and energy distributions.
