c++ - Iterator over a unique element without construction a container -


i have framework has requires input iterator. sometime, have single element, constructing container seems work.

t obj; // unique object  std::vector<t> vec; // want avoid vec.push_back(t);  // because use of container call call(std::begin(vec), std::end(vec));  // want call(beginfakesingletonit<t>(obj), endfakesingletonit<t>());

i create special type of iterator, doesn't exist in standard library or boost?

a single element can thought of array of size one. if use pointer object pointer(iterator) start of array , pointer 1 past end of array pointer incremented once. can use

call(&object, &object + 1)

and process single object.

android - Unable to generate FCM token from dynamically instantiated Firebase -

our business logic requires instantiate firebase during runtime. fetch firebase credentials (app id, api key etc.) default firebase location after knowing user's public key , create firebase instance using credentials. this means there 2 firebase instances used within app: the default "index" firebase gives credentials second the actual firebase intend use point forward the second firebase initialised this: firebaseapp app = firebaseapp.initializeapp(<context>, <options>, <app_label>); our problem traditional method of retrieving fcm token using firebaseinstanceidservice , ontokenrefresh() fails since ontokenrefresh() method called first firebase instance. directly calling string token = firebaseinstanceid.getinstance(app).gettoken(); returns null never ready when called. have tried polling test if token generated @ point. no luck. how can generate fcm token reliably firebase instance instantiated during runtime? i...
