std::is_member_pointer 是一元类型特征 (UnaryTypeTrait) 。 如果T 为指向非静态成员对象或非静态成员函数的指针,那么提供的成员常量 value 等于true。对于其它任何类型,value 等于false。 如果程序添加了 std::is_member_pointer 或std::is_member_pointer_v 的特化,那么行为未定义。
Member constants value [static] true if T is a member function pointer type, false otherwise (public static member constant) Member functions operator bool converts the object to bool, returns value (public member function) operator() (C++14) returns value (public member function) Mem...
