Web28 Apr 2016 · shared_ptr consists of two things: pointer to the object and pointer to the control block (that contains reference counter for example). Control block is created only once per given pointer, so two shared_pointers (for the same pointer) will point to the same control block. Inside control block there is a space for custom deleter and allocator.

WebThe shared_pointer is a reference counting smart pointer that can be used to store and pass a reference beyond the scope of a function. This is particularly useful in the context of OOP, to store a pointer as a member variable and return it to access the referenced value outside the scope of the class. Consider the following example: Run this code
WebI am programming in C++ in UE4 and am using smart pointers, mainly TWeakObjectPtr. However, since they are a bigger size than raw pointers and UE4 automatically garbage collects UPROPERTYs, do I really need to use them? Are they faster garbage collection wise?
