我研究了 weak_ptr 。有两种获取原始指针的方法。lock() 功能 shared_ptr<Foo> spFoo = wpPtr.lock(); if(spFoo) { spFoo->DoSomething(); } expired() 功能 if(!wpPtr.expired()) { shared_ptr<Foo> spFoo = wpPtr.lock(); spFoo->DoSomething(); } 哪个是更好的方法?这两种方式有什么不...
swap():交换两个智能指针所管理的资源。 expired():检查weak_ptr所指向的资源是否有效,返回true的时候,垃圾回收进程就会清除该指针所指向的内存资源。 use_count():返回智能指针所指向shared_ptr的数量。 lock():获取weak_ptr所指向的shared_ptr实例。 用法说明: weak_ptr不占有内存资源,但是可以指向由shared_ptr...
