 Posted: Wed Dec 31, 2003 4:16 am Post subject: template class, operator T |
 |
|
I am trying to re-write some code from a book I am working on so that I
understand it's functionality.
I ran across this:
template <class T>
class Flag
{
public:
// snip
T value;
operator T() {return value;};
// snip
};
what does the operator T do? and is it not returning a value even a void?

It's returning a T. That function will be called whenever an object of
type Flag

It is an operator for type conversion. An object of the type Flag
converted to T.
