我的意思是类似const char* const p;或char const * const p;的东西.此处的p表示指针指向const char,而指针本身也是const. 因此,不会遵守*p = 'a';或char c = 'c'; p = &c;.
What I mean is something like const char* const p; or char const * const p;. The p here stand for a pointer points to a const char while the pointer itself is also const. So *p = 'a'; or char c = 'c'; p = &c; won't be complied.
请有人告诉我如何声明一个指向成员函数的指针,该成员函数指向的对象本身就是const,带有和不带有typedef.
Please someone tell me how to declare a pointer points to a member function, both what it points to and itself is const, with and without typedef.
不要只是出于好奇而在实践中使用.
Not use in practice just curious about.
这不是什么我在问.
推荐答案不能取消引用成员函数指针来修改指针,因此只需要一个const:
Member function pointers can't be dereferenced to modify the pointee, so only one const is needed:
RetType (Class::* const ptr)(Arg1Type, ..., ArgNType) = ...;使用typedefs:
With typedefs:
typedef RetType (Class::* PtrTypedefName)(Arg1Type, ..., ArgNType); const PtrTypedefName ptr = ...;希望这会有所帮助!
