移动构造函数(move constructor)和移动赋值操作符(move assignment operator)的作用是允许将临时对象或资源所有权从一个对象转移给另一个对象,而无需执行深层的数据拷贝和分配新资源。相比复制构造函数和复制赋值操作符,移动操作通常更加高效,因为它只需要重新指定资源的所有权关系,而不需要执行资源的复制或分配。 移动构...

Is my move constructor and assignment correct? I am most unsure about the std::move in the assignment, im not sure if this is the correct way of doing it. When I am testing the program it is running correctly, but ive done things in the past that worked but wasnt put together right...

std::cout << "Move assignment operator "; return *this; } }; int main() { Obj obj1; /* Default constructor */ Obj obj2 = std::move(obj1); /* Move constructor */ Obj obj3; obj3 = std::move(obj2); /* Move assignment operator */ ...
Move constructors and move assignment C++11 defines two new functions in service of move semantics: a move constructor, and a move assignment operator. Whereas the goal of the copy constructor and copy assignment is to make a copy of one object to another, the goal of the move constructor ...
The following example shows a revised version of the move constructor that calls the move assignment operator: C++ Copy // Move constructor. MemoryBlock(MemoryBlock&& other) noexcept : _data(nullptr) , _length(0) { *this = std::move(other); } The std::move function converts the ...
