问题描述
code> std :: vector 被销毁，它会调用每个项目的析构函数。是否将指针的析构函数调用到对象？
I know when an std::vector is destructed, it will call the destructor of each of its items. Does it call the destructor of pointers to objects?
vector<myclass*> stuff;
当内容被销毁时，内部指针指向的单个对象会被破坏吗？ p>
When stuff is destroyed, do the individual objects pointed to by the pointers inside stuff get destructed?
推荐答案
否。
如何 std： ：vector 应该知道如何销毁指向的对象？是否应该使用 delete ？ delete [] ？ 免费？一些其他功能？如何知道指向的对象实际上是动态分配的，或者它是一个真正的所有者，并负责销毁它们？
How is std::vector supposed to know how to destroy the pointed-to object? Should it use delete? delete[]? free? Some other function? How is it supposed to know the pointed-to objects are actually dynamically allocated or that it is the One True Owner and is responsible for destroying them?
如果 std :: vector 是指向对象的One True所有者，使用 std :: unique_ptr 以处理对象的清理。
If the std::vector is the One True Owner of the pointed-to objects, use std::unique_ptr, potentially with a custom deleter to handle the cleanup of the objects.
