1. unique_ptr 功能：独占使用指针时的最佳选择，确保同一时间只有一个智能指针可以指向对象。 特性：为裸指针添加了限制，有效预防资源泄漏。其赋值机制允许在特定情况下安全地重用指针，通过std::move函数实现所有权转移。 使用场景：适用于需要独占资源的情况。2. shared_ptr 功能：共享使用指针时的首选...
shared_ptr最初实现于Boost库中,后由 C++11 引入到 C++ STL。shared_ptr 利用引用计数的方式实现了对所管理的对象的所有权的分享,即允许多个 shared_ptr 共同管理同一个对象。像 shared_ptr 这种智能指针,《Effective C++》称之为“引用计数型智能指针”(reference-counting smart pointer,RCSP)。 shared_ptr 是...
std::unique_ptr::get vs std::shared_ptr Feb 22, 2021 at 4:21pm woohyeon (60) Hi. When you use unique_ptr, think about you need the pointer in other space. In other space, the pointer used as read only. So you can use unique_ptr::get(). It's simple, but not safety....

std::unique_ptr is by far the most used smart pointer class, so we’ll cover that one first. In the following lessons, we’ll cover std::shared_ptr and std::weak_ptr. std::unique_ptr std::unique_ptr is the C++11 replacement for std::auto_ptr. It should be used to manage any ...
shared_ptr<BaseClass> p1( new DerivedClass( args )) ; shared_ptr<DerivedClass> p2 = dynamic_pointer_cast<DerivedClass>(p1) ;but the compiler says no when the pointer is a unique_ptr.I am reading that I should use get( ) to get the raw pointer, then release the unique_ptr,...
