Detailed Description

A derived class with initialization information from the HEPRUP Fortran commonblock and event information from the HEPEUP one.

Member Function Documentation

bool setEvent ( int  idProcIn = 0)
inlinevirtual

Routine for doing the job of setting info on next event.

In some strategies the type of the next event has been set.

Call the routine that does the job.

Store process info.

Store particle info.

Store x values (here E = pup[ip][3]), but note incomplete info.

Done.

Implements LHAup.

bool setInit ( )
inlinevirtual

Routine for doing the job of setting initialization info.

Call the routine that does the job.

Store beam and strategy info.

Store process info. Protect against vanishing cross section.

Store the beam energies to calculate x values later.

Done.

Implements LHAup.
