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::Projection::clone ( ) const

pure virtualinherited

Clone on the heap.

Implemented in Rivet::ALICE::V0Multiplicity< MODE >, Rivet::ALICE::CLMultiplicity< INNER >, Rivet::ALICE::V0Trigger< MODE >, Rivet::ALICE::V0AndTrigger, Rivet::ALICE::PrimaryParticles, Rivet::AxesDefinition, Rivet::JetFinder, and Rivet::ParticleFinder.

compare()
