问题 The GCC compiler complains (see below) when I try the following. class Face needs to be incomplete because it contains pointer to class Element which similarly contains pointer to class Face . In other words, there is a circular dependency among classes. How can I fix it? error: invalid application of ‘sizeof’ to incomplete type ‘Face’ class Face; // needs to be incomplete class Element { std::vector < std::unique_ptr <Face> > face; }; class Face { std::vector < std::unique_ptr <Element> >

问题 I have an AngularJS app that has this structure: app/ ----- controllers/ ---------- mainController.js ---------- otherController.js ----- directives/ ---------- mainDirective.js ---------- otherDirective.js ----- services/ ---------- userService.js ---------- itemService.js ----- js/ ---------- bootstrap.js ---------- jquery.js ----- app.js views/ ----- mainView.html ----- otherView.html ----- index.html How do I go about creating my own image out of this and running it on a container?

问题 I have a question about my project... I need to know how to list all folders (in a string list or something) from a Windows Azure blob storage... I allready have my BlobClient and the connection to my Azure storage. Who can help me with this "problem"? 回答1: Try this code. It makes use of Storage Client library 2.0.3 : CloudStorageAccount storageAccount = CloudStorageAccount.DevelopmentStorageAccount; CloudBlobContainer blobContainer = storageAccount.CreateCloudBlobClient()

问题 Is there anything like Java's Set container in VBA? I can't find anything and Google doesn't seem to helpful since set is a reserved work in VBA. Any ideas would be great. Right now my only options are Dictionary or Array. Thanks. 回答1: VBA has a 'Collection' object built in, and many people consider the 'Dictionary' object from the MS Scripting Runtime to be sufficiently standard that it's essentially part of VBA. However, neither will enforce uniqueness for general objects. Whether or not

问题 Is there a way use STL containters with non-copyable elements? something like this: class noncopyable { noncopyable(noncopyable&); const noncopyable& operator=(noncopyable&); public: noncopyable(){}; }; int main() { list<noncopyable> MyList; //error C2248: 'noncopyable::noncopyable' : cannot access private member declared in class 'noncopyable' } 回答1: No, non-copyable elements can't be in C++ container classes. According to the standard, 23.1 paragraph 3, "The type of objects stored in these

问题 Is a shared memory/copy on write implementation for general containers (like that found in Qt's containers) superseded by C++11 move semantics and rvalue references? Where does one fail and the other succeed? Or are they complementary rather than alternatives? 回答1: Both copy on write and move semantics have been used to optimize value semantics of objects that hold their data on the heap. std::string , for example has been implemented both as a copy-on-write object, and as a move-enabled

问题 I am aware of creating web application but there is one basic doubt I have. I am sorry for asking very silly question but want to clear my doubt. How Tomcat Container handle request, I mean to say when I send a request for home.jsp page then I get the response as home.jsp page only and not a register.jsp page which at the same time might be the request given by other person requested from other corner of the world. Eg: Client A --------request(a.jsp)----------> Tomcat (check request received

问题 I have a simple container : template <class nodeType> list { public: struct node { nodeType info; node* next; }; //... }; Now, there is a function called _search which searches the list and returns a reference to the node which matched. Now, when I am referring to the return-type of the function, I think it should be list<nodeType>::node* . Is this right? When I define the function inline, it works perfectly: template <class nodeType> list { public: struct node { nodeType info; node* next; };
