42 // For thread safety: this is a shared object,
43 // mutex has been added to control access to shared resources (data members).
44 // in Getters and Setters, mutex is NOT used in GenerateOne because it is
45 // assumed that properties are not changed during event loop.
46 //
47 // Version 1.0, 05/02/2004, Fan Lei, Created.
48 // Based on the G4GeneralParticleSource class in Geant4 v6.0

52 //
53 // Class Description:
54 //
55 // To generate the position of a primary vertex according to the defined distribution
56 //
58 //
59 // MEMBER FUNCTIONS
60 // ----------------
61 //
62 // G4SPSPosDistribution ()
63 // Constructor: Initializes variables and instantiates the Navigator class
64 //
65 // ~G4SPSPosDistribution ()
66 // Destructor:
67 //
68 // void SetPosDisType(G4String)
69 // Allows user to choose Point, Plane, Surface or Volume source
70 // position distributions.
71 //
72 // void SetPosDisShape(G4String)
73 // Allows the user to choose the particular shape they wish for the
74 // position distribution. Choices are Square, Circle, Ellipse, Rectangle,
75 // Sphere, Ellipsoid, Cylinder, Parallelepiped.
76 //
77 // void SetCentreCoords(G4ThreeVector)
78 // Sets the co-ordinates of the centre of the position distribution.
79 //
80 // void SetPosRot1(G4ThreeVector)
81 // Used to specify the co-ordinate system for the position distribution
82 // along with SetPosRot2. SetPosRot1 sets the vector x' and need not be
83 // a unit vector.
84 //
85 // void SetPosRot2(G4ThreeVector)
86 // Used in connection with SetPosRot1. This sets a vector in the plane
87 // x'y'. By a series of cross products x', y', z' are generated. Again
88 // need not be a unit vector.
89 //
90 // void SetHalfX(G4double)
91 // Sets the half length in x.
92 //
93 // void SetHalfY(G4double)
94 // Sets the half length in y.
95 //
96 // void SetHalfZ(G4double)
97 // Sets the half length in z.
98 //
99 // void SetRadius(G4double)
100 // Sets the radius where appropriate for source distribution shapes.
101 //
102 // void SetRadius0(G4double)
103 // Sets the inner radius where appropriate for source distribution shapes.
104 //
105 // void SetBeamSigmaInR(G4double);
106 // Sets the sigma for 1D beam
107 //
108 // void SetBeamSigmaInX(G4double);
109 // Sets the first sigma for 2D beam
110 //
111 // void SetBeamSigmaInY(G4double);
112 // Sets the second sigma for 2D beam
113 //
114 // void SetParAlpha(G4double)
115 // Sets the angle Alpha in the Parallelepiped shapes.
116 //
117 // void SetParTheta(G4double)
118 // Sets the angle Theta in the Parallelepiped shapes.
119 //
120 // void SetParPhi(G4double)
121 // Sets the angle Phi in the Parallelepiped shapes.
122 //
123 // void ConfineSourceToVolume(G4String)
124 // Used to confine the start positions to a particular volume.
125 //
126 // void SetBiasRndm (G4SPSRandomGenerator* a) { posRndm = a ; };
127 // Sets the biased random number generator
128 //
129 // G4ThreeVector GenerateOne();
130 // Generate one random position
131 //
132 // void SetVerbosity(G4int)
133 // Sets the verbosity level.
