31 //
32 // Class description:
33 //
34 // Represents many touchable detector elements differing only in their
35 // positioning. The elements' positions are calculated by means of a simple
36 // linear formula, and the elements completely fill the containing mother
37 // volume.
38 //
39 // G4PVReplica(const G4String& pName,
40 // G4LogicalVolume *pLogical,
41 // G4LogicalVolume *pMother,
42 // const EAxis pAxis,
43 // const G4int nReplicas,
44 // const G4double width,
45 // const G4double offset=0);
46 //
47 // Replication may occur along:
48 //
49 // o Cartesian axes (kXAxis,kYAxis,kZAxis)
50 //
51 // The replications, of specified width have coordinates of
52 // form (-width*(nReplicas-1)*0.5+n*width,0,0) where n=0.. nReplicas-1
53 // for the case of kXAxis, and are unrotated.
54 //
55 // o Radial axis (cylindrical polar) (kRho)
56 //
57 // The replications are cons/tubs sections, centred on the origin
58 // and are unrotated.
59 // They have radii of width*n+offset to width*(n+1)+offset
60 // where n=0..nReplicas-1
61 //
62 // o Phi axis (cylindrical polar) (kPhi)
63 // The replications are `phi sections' or wedges, and of cons/tubs form
64 // They have phi of offset+n*width to offset+(n+1)*width where
65 // n=0..nReplicas-1
66 
67 // History:
68 // 29.07.95 P.Kent - First non-stub version
69 // 26.10.97 J.Apostolakis - Added constructor that takes mother LV
70 // 16.02.98 J.Apostolakis - Added copy number
71 // 13.01.13 G.Cosmo, A.Dotti - Modified for thread-safety for MT

95 // the fields encapsulated by the class G4ReplicaData. When each thread
96 // initializes the value for these fields, it refers to them using a macro
97 // definition defined below. For every G4PVReplica instance, there is
98 // a corresponding G4ReplicaData instance. All G4ReplicaData instances are
99 // organized by the class G4PVRManager as an array.
100 // The field "int instanceID" is added to the class G4PVReplica.
101 // The value of this field in each G4LogicalVolume instance is the subscript
102 // of the corresponding G4ReplicaData instance.
103 // In order to use the class G4PVRManager, we add a static member in the
104 // class G4LogicalVolume as follows: "static G4PVRManager subInstanceManager".
105 // For the master thread, the array for G4ReplicaData instances grows
106 // dynamically along with G4PVReplica instances arecreated.
107 // For each worker thread, it copies the array of G4ReplicaData instances
108 // from the master thread.
109 // In addition, it invokes a method similiar to the constructor explicitly
110 // to achieve the partial effect for each instance in the array.

115 // in the class G4ReplicaData.
