#include <FastJetLinkBase.h>
FastJetLinkBase is a base class defining only pointers to forwared declared fastjet classes This allows the Jet interface to return such objects without introducing an explicit dependency on fastjet
For this to work, a derived class must be implemented to be in charge of the actual management of the fastjet objects. Such a class is FastJetLink defined in the JetEDM package. It's used from the Jet_PseudoJet.icc header file
