Hi all,
Traditionally the prototype pattern (cloning) causes
the "cloned" to be copied. Is there an idiom where
the method performing the creation creates the
default type (without cloning). Small example:
template <class T>
struct clonable
{
virtual T* clone() const; //calls new T( *this );
};
template <class T>
struct xxx_able
{
virtual T* xxx() const; //calls new T();
};
Note that this is similar to factory functions, but not
entirely the same as factory functions are aware of
type.
Therefore - I want a prototype that provides the correct
type without cloning. What is the idiom called?
Regards,
Werner
