[Nfd-dev] beforeExpirePendingInterest for forwarding strategy

[Steve DiBenedetto]

Please make sure the header file's method prototype is:

virtual void

beforeExpirePendingInterest(shared_ptr<pit::Entry> pitEntry) DECL_OVERRIDE;


Also, (sorry, have to ask), did you enable TRACE logging for the
specific strategy module/all modules in the nfd config?
