// Class description:
//
// Abstract base class for user's mandatory action class for primary
// vertex/particle generation. This class has only one pure virtual
// method GeneratePrimaries() which is invoked from G4RunManager
// during the event loop.
// This class is NOT intended for generating primary vertex/particle
// by itself. This class should:
// - have one or more G4VPrimaryGenerator concrete classes such as G4ParticleGun
// - set/change properties of generator(s)
// - pass G4Event object so that the generator(s) can generate primaries.
 
// Original author: M.Asai, 1999
