Functions
templated functions for assigning values
When writing templated code, it is sometimes not possible to use operator=() for assignment, e.g. when the classes do not support that operator. The assign template tries to alleviate this problem by providing several overloads when the first argument is a (STIR) container. Usage assign(x,y); // logically equivalent to x=y; Design consideration We could have overloaded operator=() instead, but that would probably lead to surprising conversions.
template<class T, class T2>
std::enable_if_t<!has_iterator_v< T > >	stir::assign (T &x, const T2 &y)
template<class T, class T2>
std::enable_if_t< has_full_iterator_v< T > >	stir::assign (T &v, const T2 &y)
template<class T, class T2>
std::enable_if_t< has_iterator_and_no_full_iterator< T >::value >	stir::assign (T &v, const T2 &y)
void	stir::assign (double &x, const int y)
void	stir::assign (float &x, const int y)
