template<typename Result>

virtual int qlib::ace::Callback< Result >::exec ( void ) [pure virtual]

invoke this callback

Returns:: Callback_Manager manager Invoke the exec() of command, the action depends on the return value of exec(). >0 for delete this callback instance and remove it from manager =0 for remove it from callback manager but do not delete it <0 for don't remove it
