|
|
// Documentation:
|
|
// This class represents the Primary Generator that generate vertex (energy,position and direction) of primary adjoint particles.
|
|
// It is used by G4AdjointPrimaryGeneratorAction. If the adjoint source is selected by the user as being on the external boundary of a volume
|
|
// it uses the class G4AdjointPosOnPhysVolGenerator to generate the vertex positions and directions. Otherwise G4SingleParticleSource is used.
