Detailed DescriptionProject out jets found using the FastJet package jet algorithms. Definition at line 26 of file FastJets.hh. Member Typedef Documentation
Member Enumeration Documentation
Enum for the treatment of invisible particles: whether to include all, some, or none in jet-finding.
Wrapper enum for selected Fastjet jet algorithms.
Definition at line 30 of file FastJets.hh.
Enum for the treatment of muons: whether to include all, some, or none in jet-finding. Definition at line 19 of file JetAlg.hh. { NO_MUONS, DECAY_MUONS, ALL_MUONS };
Constructor & Destructor Documentation
"Wrapped" argument constructor using Rivet enums for most common jet alg choices (including some plugins). For the built-in algs, E-scheme recombination is used. For full control of FastJet built-in jet algs, use the native arg constructor. Definition at line 44 of file FastJets.hh. References FastJets::_init1(). Referenced by FastJets::clone().
Native argument constructor, using FastJet alg/scheme enums. Definition at line 51 of file FastJets.hh. References FastJets::_init2().
Explicitly pass in a JetDefinition. Definition at line 58 of file FastJets.hh. References FastJets::_init3().
Explicitly pass in an externally-constructed plugin (must be heap-allocated, Rivet will delete) Definition at line 64 of file FastJets.hh. References FastJets::_init4().

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.
