Representation of a HepMC event, and enabler of Projection caching.
Definition Event.hh:22
Project out all final-state particles in an event. Probably the most important projection in Rivet!
Definition FinalState.hh:12
Templated FS projection which can lose some of the supplied particles.
Definition LossyFinalState.hh:17
CmpState compare(const Projection &p) const
Compare projections.
Definition LossyFinalState.hh:63
virtual ~LossyFinalState()
Virtual destructor, to allow subclassing.
Definition LossyFinalState.hh:40
LossyFinalState(const FinalState &fsp, FILTER filter)
Constructor from FinalState.
Definition LossyFinalState.hh:24
void project(const Event &e)
Apply the projection on the supplied event.
Definition LossyFinalState.hh:52
LossyFinalState(FILTER filter, const Cut &c=Cuts::open())
Stand-alone constructor. Initialises the base FinalState projection.
Definition LossyFinalState.hh:32
DEFAULT_RIVET_PROJ_CLONE(LossyFinalState)
Clone on the heap.
virtual const Particles & particles() const
Get the particles in no particular order, with no cuts.
Definition ParticleFinder.hh:52
const PROJ & declare(const PROJ &proj, const std::string &name)
Register a contained projection (user-facing version)
Definition ProjectionApplier.hh:170
Base class for all Rivet projections.
Definition Projection.hh:29
void setName(const std::string &name)
Used by derived classes to set their name.
Definition Projection.hh:142
Log & getLog() const
Get a Log object based on the getName() property of the calling projection object.
Definition Projection.hh:136
Cmp< Projection > mkNamedPCmp(const Projection &otherparent, const std::string &pname) const
double p(const ParticleBase &p)
Unbound function access to p.
Definition ParticleBaseUtils.hh:684
const Cut & open()
Fully open cut singleton, accepts everything.
