◆ declareProjection()

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

Register a contained projection.

The type of the argument is used to instantiate a new projection internally: this new object is applied to events rather than the argument object. Hence you are advised to only use locally-scoped Projection objects in your Projection and Analysis constructors, and to avoid polymorphism (e.g. handling ConcreteProjection via a pointer or reference to type Projection) since this will screw up the internal type management.

◆ useInvisibles()

void Rivet::JetFinder::useInvisibles ( Invisibles  useinvis = Invisibles::DECAY)
inlineinherited

Include (some) invisible particles in jet construction.

The default behaviour is that jets are only constructed from visible particles. Some jet studies, including those from ATLAS, use a definition in which neutrinos from hadron decays are included via MC-based calibrations. Setting this flag to true avoids the automatic restriction to a VisibleFinalState.

◆ useMuons()

void Rivet::JetFinder::useMuons ( Muons  usemuons = Muons::ALL)
inlineinherited

Include (some) muons in jet construction.

The default behaviour is that jets are only constructed from visible particles. Some jet studies, including those from ATLAS, use a definition in which neutrinos from hadron decays are included via MC-based calibrations. Setting this flag to true avoids the automatic restriction to a VisibleFinalState.
