Question

Is there any way to make a class template function?

So for example

//Warning: this is conceptual pseudo-code

template<typename TemplateClass, TemplateItem>
TemplateClass &TemplateClass::operator=(TemplateItem &B)
{
   Item = B.Item;
   return *this;
}

//or...

template<typename TemplateClass, TemplateItem>
TemplateClass &TemplateClass::Assignment(TemplateItem &B)
{
   Item = B.Item;
   return *this;
}

Assignment<TestA,TestB>(B);

Or something along those lines.

It isn’t just for assignments, I’ll comment.

I’m sure I’ll get bashed by the “preprocessor is evil” group, but I think you are looking for something like this:

#define DEFINE_ASSIGNMENT(mainClass,memberClass,member)        \
mainClass & mainClass::operator = (const memberClass & rhs)    \
{                                                              \
    member=rhs.member;                                         \
    return *this;                                              \
}

DEFINIE_ASSIGNMENT(TestA,TestB,Item)
