◆ 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 virtual

Clone on the heap.

Implements Rivet::Projection.

Implemented in Rivet::ALICE::PrimaryParticles.

◆ compare()

◆ declare() [1/2]

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

Register a contained projection (user-facing version)

Todo:
Add SFINAE to require that PROJ inherit from Projection
