Abstract base class container for multi-particle events.
This base class defines the basic functionality and interface for all event classes, which in addition to handling a collection of massive particles, also have in common the following functionality:
- an associated list of parameters, accessible through the GetParameters() and SetParameter() methods;
- iterators for looping over all or a subset of the particles of the event;
- methods for defining named subsets ('groups') of particles according to various selection criteria;
- methods for defining/modifying different relativistic reference frames in which to 'view' the particles of the event
Concrete implementations of event classes (which define the type of particle objects used) derive from child class KVTemplateEvent. Note that any class derived from KVParticle can be used in an event (representing relativistic massive particles), not only KVNucleus and daughter classes.
Adding particles to an event
Particles are added to an event using methods AddParticle() or AddNucleus(). The first method returns a KVParticle pointer to the added particle while the latter casts to a KVNucleus pointer for classes which derive from KVNucleus, returning nullptr if not (but a particle is still created and added to the event):
auto p =
e.AddParticle();
if(n) {
std::cout << "Event contains objects derived from KVNucleus" << std::endl;
}
else {
std::cout << "n == nullptr : Event contains objects NOT derived from KVNucleus" << std::endl;
}

The number of particles in the event, its size or multiplicity, is given by GetMult():

- Warning
- Only use with events containing objects derived from KVNucleus
Use this method to iterate over the list of nuclei in the event After the last particle GetNextNucleus() returns a null pointer and resets itself ready for a new iteration over the particle list.
If opt="" all particles are included in the iteration. If opt="ok" or "OK" only nuclei whose KVNucleus::IsOK() method returns kTRUE are included.
Any other value of opt is interpreted as a (case-insensitive) particle group name: only particles with BelongsToGroup(opt) returning kTRUE are included.
If you want to start from the beginning again before getting to the end of the list, especially if you want to change the selection criteria, call method ResetGetNextNucleus() before continuing.
If you interrupt an iteration before the end, then start another iteration without calling ResetGetNextNucleus(), even if you change the argument of the call to GetNextNucleus(), you will repeat exactly the same iteration as the previous one.
- Warning
- Only one iteration at a time over the event can be performed using this method. If you want/need to perform several i.e. nested iterations, see KVTemplateEvent::EventIterator
