// G4AdjointPrimaryGenerator

|
|
// Class description:
|
|
//
|
|
// This class represents the Primary Generator that generates 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.
