Hi all I've implemented a feature function in the old version of Moses and it works fine. I'd like to re-implement my code in the new version of moses, but it get's this error: ./moses/FF/Aref.h:330:50: error: cannot allocate an object of abstract type ‘Moses::ArefState’ ./moses/FF/Aref.h:271:7: note: because the following virtual functions are pure within ‘Moses::ArefState’: In file included from ./moses/FF/Aref.h:5:0,from moses/FF/Factory.cpp:4:./moses/FF/FFState.h:15:18: note: virtual size_t Moses::FFState::hash() const./moses/FF/FFState.h:16:16: note: virtual bool Moses::FFState::operator==(const Moses::FFState&) const
I guess I should implement hash() and == functions. right? If so, could anyone please tell me what's the task of these functions? -- Arefeh Kazemi
