In my Single Document Application I have this situation:
class CObj
{
public:
int m_nValue;
// Rest of class implementation
};
typedef std::vector<CObj> CObjects;
typedef std::unordered_map<double, CObjects> CObjects_2;
typedef std::map<CString, CObjects_2> CObjects_3;
class CMyDoc : public CDocument
{
protected:
CObjects_3 m_Data;
public:
inline CObjects_3 & Data()
{
return m_Data;
}
}
// Somewhere in the program:
//...
// Assuming that all keys exist:
CObjects_3 & non_auto_data = pValidDocPointer->Data();
non_auto_data[_T("Key")][3.0][0].m_nValue = 10;
auto auto_data = m_pValidDocPointer->Data();
auto_data[_T("Key")][3.0][0].m_nValue = 20;
//...
Now, if I understood well how keyword auto works, I expect that
pValidDocPointer->m_Data[_T("Key")][3.0][0].m_nValue
will have a value of 20, but I see 10. Is that a Visual Studio bug or it is correct? If correct: what I misunderstood in auto keyword functioning?
