| 36 | // Implemented for the new scheme 23 Mar. 1998 H.Kurahige |
---|
| 37 | // |
---|
| 38 | // Class Description |
---|
| 39 | // This class is a concrete class for ParticleChange which |
---|
| 40 | // has all functionality in old scheme. |
---|
| 41 | //- |
---|
| 42 | // This class contains the results after invocation of a physics process. |
---|
| 43 | // This includes final states of parent particle (momentum, energy, |
---|
| 44 | // etc) and secondary particles generated by the interaction. |
---|
| 45 | // The tracking assumes that all the values of energy and |
---|
| 46 | // momentum are in global reference system, therefore all the |
---|
| 47 | // needed Lorentz transformations must have been already Done |
---|
| 48 | // when filling the data-members of this class. |
---|
| 49 | //- |
---|
| 50 | // --------------------------------------------------------------- |
---|
| 51 | // IMPORTANT NOTE: Although the name of the class and methods are |
---|
| 52 | // "Change", what it stores (and returns in get) are the "FINAL" |
---|
| 53 | // values of the Position, Momentum, etc. |
---|
| 54 | // |
---|
| 55 | // ------------------------------------------------------------ |
---|
| 56 | // modify AddSecondary methods for "GoodForTracking" flag |
---|
| 57 | // 8 June 1998 H.Kurashige |
---|
| 58 | // Add Track weight 12 Nov. 1998 H.Kurashige |
---|
| 59 | // Add Get/SetMomentumDirectionChange 6 Feb. 1999 H.Kurashige |
---|
| 60 | // Add Get/SetDynamicMass 5 Oct. 1999 H.Kurashige |
---|
| 61 | // Add Get/SetDynamicCharge 5 Oct. 1999 H.Kurashige |
---|
| 62 | // Rename SetXXX methods to ProposeXXX DynamicCharge Oct. 2005 H.Kurashige |
---|
| 63 | // Add get/ProposeMagneticMoment Mar 2007 H.Kurashige |
---|
| 64 | // Fix treatment of weight Mar 2007 H.Kurashige |
