Public Member Functions | |
| void | resize (int nup) |
| Set the NUP variable, corresponding to the number of particles in the current event, to nup, and resize all relevant vectors accordingly. | |
| void | resize () |
| Assuming the NUP variable, corresponding to the number of particles in the current event, is correctly set, resize the relevant vectors accordingly. | |
Standard constructors and destructors. | |

The members are named in the same way as in the common block. However, fortran arrays are represented by vectors, except for the arrays of length two which are represented by pair objects.

| pair<double,double> ThePEG::HEPEUP::XPDWUP |
The PDF weights for the two incoming partons.
Note that this variable is not present in the current LesHouches accord (hep-ph/0109068), hopefully it will be present in a future accord.
