79 // The type G4RegionManager is introduced to encapsulate the methods used by
80 // both the master thread and worker threads to allocate memory space for
81 // the fields encapsulated by the class G4RegionData. When each thread
82 // initializes the value for these fields, it refers to them using a macro
83 // definition defined below. For every G4Region instance, there is a
84 // corresponding G4RegionData instance. All G4RegionData instances are
85 // organized by the class G4RegionManager as an array.
86 // The field "int instanceID" is added to the class G4Region.
87 // The value of this field in each G4Region instance is the subscript
88 // of the corresponding G4RegionData instance.
89 // In order to use the class G4RegionManager, we add a static member in
90 // the class G4Region as follows: "static G4RegionManager subInstanceManager".
91 // For the master thread, the array for G4RegionData instances grows
92 // dynamically along with G4Region instances are created. For each worker
93 // thread, it copies the array of G4RegionData instances from the master thread.
94 // In addition, it invokes a method similiar to the constructor explicitly
95 // to achieve the partial effect for each instance in the array.
96 //
98 
99 // These macros changes the references to fields that are now encapsulated
100 // in the class G4RegionData.
