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;
