// GEANT 4 class header file
//
//
// ------------------------------------------------------------
// Implemented for the new scheme 23 Mar. 1998 H.Kurahige
//
// Class Description
// This class is the abstract class for ParticleChange.
//-
// The ParticleChange class ontains the results after invocation
// of a physics process. This includes final states of parent
// particle (momentum, energy, etc) and secondary particles generated
// by the interaction.
// The tracking assumes that all the values of energy and
// momentum are in global reference system, therefore all the
// needed Lorentz transformations must have been already Done
// when filling the data-members of this class.
//-
//-
// This abstract class has following four virtual methods
// virtual G4Step* UpdateStepForAtRest(G4Step* Step);
// virtual G4Step* UpdateStepForAlongStep(G4Step* Step);
// virtual G4Step* UpdateStepForPostStep(G4Step* Step);
// virtual void Initialize(const G4Track&);
// The UpdateStep methods return the pointer to the G4Step
// after updating the given Step information by using final state
// information of the track given by a physics process.
// User must add methods to keep the final state information
// in his derived class as well as implement UpdateStep methods
// which he want to use.
//-
// The Initialize methods is provided to refresh the final
// state information and should be called by each process
// at the beginning of DoIt.
//

// Implement Event Biasing Scheme 9 Nov.,98 H.Kurashige
// add CheckIt 13 Apr.,99 H.Kurashige
// add accuracy leveles 5 May, 99 H.Kurashige
// add check secondaries 11 June, 03 H.Kurashige
// add new methods of ProposeXXX 08 May, 04 H.Kurashige
