1.shared_ptr允许有多个指针指向同一个对象,unique_ptr独占所指向的对象。 2.类似于vector,智能指针也是模板。创建智能指针: 使用make_shared函数分配一个对象并初始化它,make_shared函数返回一个指向此对象的shared_ptr: 3.我们可以认为每个share_ptr都有一个关联的计数器,通常称为引用计数(reference count)... ...
Raw pointer allocated with new and released with delete. Description Use astd::unique_ptrinstead. Limitations Checklist for review Some things are not automated, and forgotten often. This list is a reminder for the reviewers. The bug fix is important enough to be backported? (label: 'backport ...

Hello I'm repeatedly getting an error that makes the app crash when opening the chat. I haven't found any reference to this error or any similar issue here, so this is why I'm posting it. I'm using the last version currently available (v...
pointer void reference void Member types iterator_category, value_type, difference_type, pointer and reference are required to be obtained by inheriting from std::iterator<std::output_iterator_tag, void, void, void, void>. (until C++17) Note std::raw_storage_iterator was deprecated primar...
I don't know ifSceneshouldbe copyable or not - but right now it is and that's broken. So at the very least, we can easily fix it by using a smart pointer: voidAddEntity(std::unique_ptr<Core::Entity> ); std::vector<std::unique_ptr<Core::Entity>> entities; ...
You could test your theory by advancing the file pointer past the MBR and partition table before you start to read from the image and write to the disk. After you hit end of file you could return the file pointer back to the beginning of the image to write the MBR and partition tab...
Motivation / Problem Avoiding passing new raw pointer into a smart pointer, as this temporarily creates an unmanaged object first. Description Use std::make_shared or std::make_unique instead of r...
