in boost tutorial , example of using shared pointers, have class a, , create shared pointer pointing object of class a : boost::shared_ptr<a> spa(new a); then serialize it: std::ofstream ofs(filename.c_str()); boost::archive::text_oarchive oa(ofs); oa << spa; so why class a have have function? void serialize(archive & ar, const unsigned int /* file_version */); the reason want use shared pointer avoid defining function of complex classes. i'm not using shared pointer, i'm using real pointer, , i'm serializing address pointer pointing at. the reason want use shared_pointer avoid defining function of complex classes. in opinion, wrong reason use shared pointers. using shared pointers is good, reason memory management you, not have call delete yourself. in (rare) cases, using smart pointers may not best solution , prefer memory management yourself. important criteria decide use smart pointers or not, serialization being side ...

i looking write files multiple times (100k+) , writes happen on flaky network. this, considering using java executorservice generate threads, i'm not quite sure combination of settings make following happen: only allow 1 write happen @ time (order matters of course) allow write ample time conduct each write (say 5 second) @ point bail if writing slow, have executor collect writes in queue , wait. don't allow overall program exit until thread queue empty. separate threads writers. i.e., if same exact writer comes in function, put in own queue. if different writer pointer comes in, give own queue (no need put separate writers in same queue). i believe can done combination of executor features along .wait() , .notify() command on main program's object. however, not sure how precisely work executor api done. here got: private void writetofileinseperatethread(final printwriter writer, final string text) { executorservice executor = executors.newsinglethrea...
