i trying make logout button app , doesn't seem work. please check code? thank you! using fb sdk 4.0

        facebooksdk.sdkinitialize(getapplicationcontext());     callbackmanager = callbackmanager.factory.create();     setcontentview(r.layout.activity_main);      logout= (imageview) findviewbyid(r.id.logout);

here's logout onclick

        logout.setonclicklistener(new view.onclicklistener() {          @override         public void onclick(view v) {             // todo auto-generated method stub             loginmanager.getinstance().logout();             hideall();             reset();         }     });

here's fb share udf

    public void sharefbsure() {     list<string> permissionneeds = arrays.aslist("publish_actions");      manager = loginmanager.getinstance();      manager.loginwithpublishpermissions(this, permissionneeds);      manager.registercallback(callbackmanager, new  facebookcallback<loginresult>()    {         @override         public void onsuccess(loginresult loginresult)         {             publishimage();         }          @override         public void oncancel()         {            system.out.println("oncancel");         }          @override         public void onerror(facebookexception exception)         {             system.out.println("onerror");         }     });

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
