std::is_member_function_pointer 是一元类型特征 (UnaryTypeTrait) 。 检查T 是否为非静态成员函数指针。如果 T 为非静态成员函数指针类型,那么提供的成员常量 value 等于true。否则,value 等于false。 如果程序添加了 std::is_member_function_pointer 或std::is_membe
allocated bynew, however, this renders every pointer to the deallocated object invalid, including thethispointer itself: afterdelete this;returns, such member function cannot refer to a member of a class (since this involves an implicit dereference ofthis) and no other member function may be ...
In simple cases, a data member pointer simply stores the offset of a data member relative to the beginning of the object, and a member function pointer is simply the address of the member function. Smart pointers There is no extra cost to accessing an object through a smart pointer. Accessi...

转自:“http://www.cnblogs.com/nbsofer/p/get_member_function_address_cpp.html” 这里, 我整理了4种C++中取成员函数地址的方法, 第1,2,4种整理于网上的方法, 第3种cdecl_cast是我自己想到的. 其中, 第4种(汇编)的方法不能在VC6上编译通过. 推荐使用第1,2种方法(pointer_cast 和 union_cast). ...
Keep in mind when using member function pointers that they are different from regular function pointers. Casting between a member function pointer and a regular function pointer will not work. For example, member functions in Microsoft's compilers use an optimized calling convention called thiscall th...
