It captures any arguments to the method by value // when Bind is called, producing a stateful, nullary function object. Care // should be taken about the lifetime of objects captured by Bind(); the // returned functor knows nothing about the lifetime of the method's object or // any arguments passed by pointer, and calling the functor with a destroyed // object will surely do bad things. // // Example usage: // struct Foo { // int Test1() { return 42; } // int Test2() const { return 52; } // int Test3(int x) { return x*x; } // float Test4(int x, float y) { return x + y; } // }; // // int main() { // Foo foo; // cout << rtc::Bind(&Foo::Test1, &foo)() << endl; // cout << rtc::Bind(&Foo::Test2, &foo)() << endl; // cout << rtc::Bind(&Foo::Test3, &foo, 3)() << endl; // cout << rtc::Bind(&Foo::Test4, &foo, 7, 8.5f)() << endl; // } #ifndef WEBRTC_BASE_BIND_H_ #define WEBRTC_BASE_BIND_H_ #define NONAME namespace rtc { namespace detail { // This is needed because the template parameters in Bind can't be resolved // if they're used both as parameters of the function pointer type and as // parameters to Bind itself: the function pointer parameters are exact // matches to the function prototype, but the parameters to bind have // references stripped.
