'scalar deleting destructor' 和 'vector deleting destructor'的区别

在C++的的虚表中的以一个函数往往是'scalar deleting destructor'或 'vector deleting destructor'，这两个函数的主要区别是：

void scalar_deleting_destructor(A* pa) { pa->~A(); A::operator delete(pa); }

void vector_deleting_destructor(A* pa, size_t count) { for (size_t i = 0; i < count; ++i) pa[i].~A(); A::operator delete[](pa); }

scalar deleting destructor代表对象的析构函数代理；对应的delete A;

 'vector deleting destructor'代表对象数组的析构函数代理； 对应的delete [] A;
