创建一个CMap，它保存另一个CMap作为值 [英] Creating a CMap which holds another CMap as a value

问题描述

我试图创建一个CMap，它有一个CString作为键和一个CMap作为一个值。显然，以下是不工作，但我不知道它是如何工作的。

  CMap< CString，LPCSTR，CMap< CString， LPCSTR，int，int>，CMap< CString，LPCSTR，int，int> xyWhatEver;任何人都有一个想法如何使用CMap在c ++中实现这样的数据结构？
 $ b 
 
 
 $ b 
解决方案
 CMap没有复制构造函数。我建议使用STL类，而不是mfc。当然，你可以替换CMap到CMap *，但这将需要额外的分配/释放步骤。
  typedef CMap< CString，LPCSTR ，int，int> tInnerMap; 
 CMap< CString，LPCSTR，tInnerMap *，tInnerMap *>地图; 
  
 
I am trying to create a CMap which has a CString as a key and a CMap as a value. Obviously  the following is not working but I have no clue how it is working.
CMap<CString, LPCSTR, CMap<CString, LPCSTR, int, int>, CMap<CString, LPCSTR, int, int>> xyWhatEver;
Anybody has an idea how to implement such a datastructure in c++ using CMap?
解决方案
CMap doesn't have copy constructor. I'd suggest using STL classes instead of mfc. Of course you can replace CMap to CMap*, but this will require additional allocating/freeing steps.
typedef CMap<CString, LPCSTR, int, int> tInnerMap;
CMap<CString, LPCSTR, tInnerMap*, tInnerMap*> map;
