Detailed Description

Wrapper projection for smearing Jets with detector resolutions and efficiencies.

Constructor & Destructor Documentation

SmearedParticles()

template<typename... Args, typename = std::enable_if_t< allArgumentsOf<ParticleEffSmearFn, Args...>::value >>

Rivet::SmearedParticles::SmearedParticles ( const ParticleFinder &  pf, const Cut &  c, Args &&...  effSmearFns  )

inline

Constructor with a variadic ordered list of efficiency and smearing function args.

Note

The Cut must be provided before the eff/smearing functions

Todo:

Wouldn't it be nice if the Cut could also go after the parameter pack?

Member Function Documentation

apply()

template<typename PROJ = Projection>

std::enable_if_t< std::is_base_of< Projection, PROJ >::value, const PROJ & > Rivet::ProjectionApplier::apply ( const Event &  evt, const Projection &  proj  ) const

inlineinherited

Apply the supplied projection on event evt.

Apply the supplied projection on event evt (user-facing alias).

Referenced by Rivet::ALICE::V0Trigger< MODE >::project().

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()

virtual unique_ptr< Projection > Rivet::ParticleFinder::clone ( ) const

pure virtualinherited

Clone on the heap.

Implements Rivet::Projection.

Implemented in Rivet::ALICE::PrimaryParticles.

compare()

CmpState Rivet::SmearedParticles::compare ( const Projection &  p ) const

inlinevirtual

Compare to another SmearedParticles

Note

Comparing detector functions doesn't work for functors/lambdas, hence are always treated as not equivalent

Reimplemented from Rivet::ParticleFinder.
