String to enum in C++
You can set up a map that you can use over and over:
template <typename T>
class EnumParser
{
map <string, T> enumMap;
public:
EnumParser(){};
T ParseSomeEnum(const string &value)
{
map <string, T>::const_iterator iValue = enumMap.find(value);
if (iValue == enumMap.end())
throw runtime_error("");
return iValue->second;
}
};
enum SomeEnum
{
Value1,
Value2
};
EnumParser<SomeEnum>::EnumParser()
{
enumMap["Value1"] = Value1;
enumMap["Value2"] = Value2;
}
enum OtherEnum
{
Value3,
Value4
};
EnumParser<OtherEnum>::EnumParser()
{
enumMap["Value3"] = Value3;
enumMap["Value4"] = Value4;
}
int main()
{
EnumParser<SomeEnum> parser;
cout << parser.ParseSomeEnum("Value2");
}
std::map< string, enumType> enumResolver;
