I would like to return a noncopyable object of type Foo from a function. This is basically a helper object which the caller will use to perform a set of actions, with a destructor to perform some clea
While trying to understand Rvalue references from here, I am unable to understand two things If there are N strings in the vector, each copy could require as
In perfect forwarding, std::forward is used to convert the named rvalue references t1 and t2 to unnamed rvalue references. What is the purpose of doing that? How would that affect the called function
Is the following code le开发者_如何学JAVAgal? std::string&& x = \"hello world\"; g++ 4.5.0 compiles this code without any problems.This is discussed on usenet currently. See Rvalue referenc
The min algorithm is normally expressed like this: template <typename T> const T& min(const T& x, const T& y)
#include <vector> #include <memory> using namespace std; class A { public: A(): i(new int) {} A(A const& a) = delete;
I recently installed Visual Studio 2010 Professional RC to try it out and test the few C++0x features that are implemented in VC++ 2010.
First: where are std::move and std::forward defined?I know what they do, but I can\'t find proof that any standard header is required to include them.In gcc44 sometimes std::move is available, and som
§3.10 section 9 says \"non-class rvalues always have cv-unqualified types\". That made me wonder... int foo()
In C++11, we can get an efficiency boost by using std::move when we want to move (destructively copy) values into a container:
