// CHANGE HISTORY
// --------------
//      ChangeHistory: 
//      November 2009 creation by L. Desorgher, Splitting of G4AdjointPrimaryGeneratorAction in two classes  G4AdjointPrimaryGeneratorAction and G4AdjointPrimaryGenerator          
//
//-------------------------------------------------------------
//  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. 
//
