#define G4PDefManager_HH
// The type G4PDefManager 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 G4PDefData. When each thread
// changes the value for these fields, it refers to them using a macro
// definition defined below. For every G4ParticleDefinition instance,
// there is a corresponding G4PDefData instance. All G4PDefData instances
// are organized by the class G4PDefManager as an array.
// The field "int g4particleDefinitionInstanceID" is added to the class
// G4ParticleDefinition.
// The value of this field in each G4ParticleDefinition instance is the
// subscript of the corresponding G4PDefData instance.
// In order to use the class G4PDefManager, we add a static member in the
// class G4ParticleDefinition as follows:
// "static G4PDefManager subInstanceManager".
// Both the master thread and worker threads change the length of the array
// for G4PDefData instances mutually along with G4ParticleDefinition
// 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.
