std::vector<int> StringToEnumValue

(

const std::vector< std::string > &

enumNames

)

Convert a vector<string> into a vector<int> with the enum values it corresponds to. Example:

std::vector<std::string> names; names.push_back("kWeird"); names.push_back("kGood");

std::vector<int> ints = StringToEnumValue<EcalRecHit::Flags>(names);

std::copy(ints.begin(), ints.end(), std::ostream_iterator<int>(std::cout, "-"));
