推導指南(C++17)

 

template< class T, class U, class V > std::basic_ostream<U, V>& operator<<( std::basic_ostream<U, V>& os, const std::shared_ptr<T>& ptr );

將儲存在 ptr 中的指標值插入到輸出流 os 中。

等效於 os << ptr.get()。

引數

os	-	一個 std::basic_ostream 物件，用於插入 ptr
ptr	-	要插入到 os 中的資料

返回值

os

示例

執行此程式碼

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

可能的輸出

0x6d9028
0x6d9028
