|
// 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.
