[英]std::bind a static member function inside the class
我試圖存儲一個稍后調用的函數,這里是一個片段。
這很好用:
void RandomClass::aFunc( int param1, int param2, double param3, bool isQueued /*= false */ )
{
/* If some condition happened, store this func for later */
auto storeFunc = std::bind (&RandomClass::aFunc, this, param1, param2, param3, true);
CommandList.push( storeFunc );
/* Do random stuff */
}
但是,如果RandomClass是靜態的,那么我相信我應該這樣做:
void RandomClass::aFunc( int param1, int param2, double param3, bool isQueued /*= false */ )
{
/* If some condition happened, store this func for later */
auto storeFunc = std::bind (&RandomClass::aFunc, param1, param2, param3, true);
CommandList.push( storeFunc );
/* Do random stuff */
}
但這不起作用,我得到編譯錯誤
錯誤C2668:'std :: tr1 :: bind':對重載函數的模糊調用
任何幫助贊賞。
指向靜態成員函數的指針類型看起來像是指向非成員函數的指針:
auto storeFunc = std::bind ( (void(*)(WORD, WORD, double, bool))
&CSoundRouteHandlerApp::MakeRoute,
sourcePort, destPort, volume, true );
這是一個簡化的例子:
struct Foo
{
void foo_nonstatic(int, int) {}
static int foo_static(int, int, int) { return 42;}
};
#include <functional>
int main()
{
auto f_nonstatic = std::bind((void(Foo::*)(int, int))&Foo::foo_nonstatic, Foo(), 1, 2);
auto f_static = std::bind((int(*)(int, int, int))&Foo::foo_static, 1, 2, 3);
}
