bool   
) const
protectedinherited

◆ before()

bool Rivet::Projection::before ( const Projection p) const
inherited

Determine whether this object should be ordered before the object p given as argument. If p is of a different class than this, the before() function of the corresponding type_info objects is used. Otherwise, if the objects are of the same class, the virtual compare(const Projection &) will be returned.

◆ clone()

inlinevirtual

Clone this projection.

Implements Rivet::ParticleFinder.

◆ compare()

virtual CmpState Rivet::ALICE::PrimaryParticles::compare ( const Projection p) const
inlinevirtual

Compare to projections.

Parameters
pProjection to compare to.
Returns
true (EQUIVALENT) if the projection p is of the same type as this, if the cuts are equal, and that the list of PDG IDs are the same.

Reimplemented from Rivet::PrimaryParticles.

template<typename PROJ >
const PROJ & Rivet::ProjectionApplier::declare ( const PROJ &  proj,
const std::string &  name 
) const

◆ hasDecayed()

virtual bool Rivet::PrimaryParticles::hasDecayed ( ConstGenParticlePtr  p) const
protectedvirtualinherited

Check if a particle p has decayed.

Parameters
pPointer to HepMC particle
Returns
true if the particle has decayed according to the status flag of the particle p

◆ isBeam()

virtual bool Rivet::PrimaryParticles::isBeam ( ConstGenParticlePtr  p) const
protectedvirtualinherited

Check if a particle is a beam (remnant) particle.

Parameters

Parameters
pParticle to investigate.

true if the particle PDG ID is in the list of known primary PDG IDs.
Note
We explicitly override this to allow for nuclei, and we explicitly check for a specific set of particles (and anti-particles). This means we do not use the base class list of particles. Therefore, we also need to override the compare method.
