Assuming I have a class like the following:
template <typename T>
struct point : boost::additive<point<T>, T>
{
T x_;
T y_;
explicit point(T x=0, T y=0) : x_(x), y_(y)
{ }
operator += (T offset)
{
x_ += offset;
y_ += offset;
}
operator -= (T offset)
{
x_ -= offset;
y_ -= offset;
}
}
Now I want to change the addition and subtraction operators to allow for
different types using the following template
class point ...
template <typename U>
operator += (U offset)
{
x_ += offset;
y_ += offset;
}
template <typename U>
operator -= (T offset)
{
x_ -= offset;
y_ -= offset;
}
...
I cannot figure out how to write the proper syntax for the boost::additive
class, so that it generates the proper additional operators for all type
combinations. Is that possible, at all?
Thanks, Peter
