Detailed Description

Description: makes jets using FFTJet clustering tree

Implementation: [Notes on implementation]

Description: makes jets using FFTJet clustering tree

Implementation: If you want to change the jet algorithm functionality (for example, by providing your own jet membership function), derive from this class and override the appropriate parser method (for example, parse_jetMembershipFunction). At the end of your own parser, don't forget to call the parser of the base class in order to get the default behavior when your special configuration is not provided (this is known as the "chain-of-responsibility" design pattern). If you also need to override "beginJob" and/or "produce" methods, the first thing to do in your method is to call the corresponding method of this base.
