c++ - 无名结构的构造函数

Question

我有一个类似这样的类:

template <class T>
class bag
{
public:

private:
 typedef struct{void* prev; struct{T item; unsigned int count;} body; void* next;}* node; 
 typedef struct{
  node operator->() { return current; }
  operator(){;} // <- i can not do that, right?

 private:
  node current;
 } iterator;
//...
};

那么，如何为 bag::iterator 编写构造函数呢？

Answer 1

给它取个好听的名字:-)

typedef struct NoName1 {void* prev; NoName1(){}; struct NoName2{T item; unsigned int count; NoName2() {}} body; void* next;}* node;

编辑:大声笑抱歉，写错了，但原理是一样的:-)
