How can I write a function template for all types with a particular type trait?
- by TC
Consider the following example:
struct Scanner
{
template <typename T>
T get();
};
template <>
string Scanner::get()
{
return string("string");
}
template <>
int Scanner::get()
{
return 10;
}
int main()
{
Scanner scanner;
string s = scanner.get<string>();
int i = scanner.get<int>();
}
…
