//  GEANT 4 class header file 
// Class Description:
//      This class is an virtual class for constructing 
//      particles and processes. This class objects will be
//      registered to G4VPhysicsList.
//
//      User must implement following four virtual methods
//      in his own concrete class derived from this class. 
//
//      all necessary particle type will be instantiated
//      virtual void ConstructParticle();
// 
//      all physics processes will be instantiated and
//      registered to the process manager of each particle type 
//      virtual void ConstructProcess();
//
//      Only one physics constructor can be registered to
//      Modular Physics List for each "physics_type".
//      Physics constructors with same "physics_type" can be
//      replaced by using the method of 
//      G4VModularPhysicsList::ReplacePhysics()
//      
//

// The type G4VPCManager is introduced to encapsulate the methods used by
// both the master thread and worker threads to allocate memory space for
// the fields encapsulated by the class G4VPCData. When each thread
// changes the value for these fields, it refers to them using a macro
// definition defined below. For every G4VPhysicsConstructor instance,
// there is a corresponding G4VPCData instance. All G4VPCData instances
// are organized by the class G4VUPLManager as an array.
// The field "int g4vuplInstanceID" is added to the class G4VUserPhysicsList.
// The value of this field in each G4VUserPhysicsList instance is the
// subscript of the corresponding G44VUPLData instance.
// In order to use the class G44VUPLManager, we add a static member in the class
// G4VUserPhysicsList as follows: "static G4VUPLManager subInstanceManager".
// Both the master thread and worker threads change the length of the array
// for G44VUPLData instances mutually along with G4VUserPhysicsList
// instances are created. For each worker thread, it dynamically creates ions.
// Consider any thread A, if there is any other thread which creates an ion.
// This ion is shared by the thread A. So the thread A leaves an empty space
// in the array of G4PDefData instances for the ion.
//
// Important Note: you may wonder why we are introducing this mechanism
//                 since there is only one PL for each application.
//                 This is true, in the sense that only one PL is allowed
//                 to be associated to a G4RunManager, however user can instantiate
//                 as many PLs are needed and at run-time select one of the PLs to be used
//                 we thus need this mechanism to guarantee that the system works without
//                 problems in case of this (unusual) case. This may be reviewed in the future

// This macros change the references to fields that are now encapsulated
// in the class G4VPCData.
//
// Note1:  the use of this-> this is needed to avoid compilation errors
// when using templated class with T=G4VUserPhysicsList. Don't know why.
// Note2: the name of the first #define is different, because otherwise
//        we need to change its use in all classes that inherits from
//        this base class (all examples). However one should note comment
//        on JIRA task: http://jira-geant4.kek.jp/browse/DEV-27
