std::shared_ptr::operator<<

STD：：共享[医]PTR：：操作符<<

template basic_ostream& operator<<(basic_ostream& os, const shared_ptr& ptr​​

插入shared_ptr<T>变成std::basic_ostream...

相当于os << ptr.get()...

参数

os-a std::basic_ostream to insert ptr into
ptr-the data to be inserted into os

返回值

os...

例

二次

#include <iostream>
#include <memory>
 
class Foo {};
 
int main()
{
    auto sp = std::make_shared<Foo>(
    std::cout << sp << std::endl;
    std::cout << sp.get() << std::endl;
}

二次

可能的产出：

二次

0x6d9028
0x6d9028

二次

另见

getreturns the stored pointer (public member function)
