template <class T, T (*FS)(const char*), const HG_String (*TS)(T)>
class IE_UTILS_API HG_Numeric
{
public:
HG_Numeric();
HG_Numeric(T);
HG_Numeric(const char*);
HG_Numeric(const HG_String&);
HG_Numeric& operator=(T v);
operator T() const;
bool isSet() const;
const HG_String toString() const;
private:
T m_num;
bool m_isSet;
};
....................
//
// HG_Bool
//
typedef HG_Numeric<bool,atob, bool_to_str> HG_Bool;
//
// HG_Char
//
typedef HG_Numeric<char,atoc,char_to_str> HG_Char;
//
// HG_Short
//
typedef HG_Numeric<short,atos,short_to_str> HG_Short;
//
// HG_Double
//
double hg_atof(const char *sz);
typedef HG_Numeric<double,hg_atof,double_to_str> HG_Double;
