Select the flavours/kinematics/colours of the two beam remnants.
Select the flavours/kinematics/colours of the two beam remnants. Notation: iPar = all partons, iSys = matched systems of two beams, iRem = additional partons in remnants.
Update to current CM energy.
Check that flavour bookkept in event and in beam particles agree.
Deeply inelastic scattering needs special remnant handling. Here getGammaMode separates from photoproduction.
Number of scattering subsystems. Size of event record before treatment.
Store event as it was before adding anything.
Two different methods to add the beam remnants.
Store event before doing colour reconnections.
Check that the new colour structure is physical.
If no colour reconnection, just check the colour configuration once.
Possibility to add vertex information to beam particles and remnants.
Restore event and return false if colour reconnection failed.
Done.
| bool init | ( | PartonVertexPtr | partonVertexPtrIn, |
| ColRecPtr | colourReconnectionPtrIn | ||

Initialization.
Save pointers.
Width of primordial kT distribution.
Handling of rescattering kinematics uncertainties from primodial kT.
Choice of beam remnant and colour reconnection scenarios.
Do multiparton interactions.
Flags for photoproduction from either (or both) side.
Check that remnant model and colour reconnection model work together.
Total and squared CM energy at nominal energy.
Initialize junction splitting class.
Possibility to set parton vertex information.
Done.

If an object needs to set up infoPtr for sub objects, override this and call registerSubObject for each object in question.
