问题 Consider the following simple code: struct Base { Base() = default; Base(const Base&); Base(Base&&); }; struct Derived : Base { }; Base foo() { Derived derived; return derived; } clang 8.0.0 gives a warning -Wreturn-std-move on it: prog.cc:21:10: warning: local variable 'derived' will be copied despite being returned by name [-Wreturn-std-move] return derived; ^~~~~~~ prog.cc:21:10: note: call 'std::move' explicitly to avoid copying return derived; ^~~~~~~ std::move(derived) But if one called

问题 I have a RESTful web service which represent processes and activities. Each activity is inside one and only one process. I would like to represent a "move" operation of activity between the process it is currently in and another process. I've look at forums and found people suggest to use MOVE operation which is not very standard and other suggest to use PUT but then I'm not sure how to tell the difference between PUT that update and PUT that moves which looks semantically wrong. Any ideas?

问题 This question already has answers here : Drag and Resize undecorated JFrame (2 answers) Closed 5 years ago . I've been making an undecorated JFrame so far and I was wondering if it's possible to move the undecorated JFrame by holding click on a JPanel. Here is the source code I'm working on. private static void createFrame() { JFrame frame = new JFrame("Text Frame"); frame.setLayout(null); frame.setSize(500,300); frame.setUndecorated(true); JPanel panel = new JPanel(); panel.setBounds(0, 2,

问题 Let's consider an std::unordered_set of std::unique_ptr<T> as an example. Can I move an element of the set elsewhere ? #include <unordered_set> #include <iostream> #include <memory> #include <vector> int main() { std::unordered_set<std::unique_ptr<int>> mySet; mySet.insert(std::make_unique<int>(1)); mySet.insert(std::make_unique<int>(2)); mySet.insert(std::make_unique<int>(3)); std::vector<std::unique_ptr<int>> myVector; for (auto&& element : mySet) { std::cout << *element << std::endl; /

问题 I have a struct like this: struct OBJ { int x; const int y; OBJ& operator=(OBJ &&oth) { y = oth.y; // this is disallowed return *this; } } And an example code void func() { static OBJ obj; OBJ other; // random values if(conditon) obj = std::move(other); //move } I understand this as obj is Non const OBJ with const member y . I can't change just y but I should be able to change whole object (call destructor and constructor). Is this possible or the only proper solution is to remove my const

问题 Consider this program that essentially creates std::thread that calls the function func() with arg as argument: #include <thread> #include <iostream> struct foo { foo() = default; foo(const foo&) { std::cout << "copy ctor" << std::endl; } foo(foo&&) noexcept { std::cout << "move ctor" << std::endl; } }; void func(foo){} int main() { foo arg; std::thread th(func, arg); th.join(); } My output is copy ctor move ctor move ctor As far as I understand arg is copied internally in the thread object
