Access typedef as non-static member of class?

Question

Basically, what I want to do is something like this:

template<typename x,typename y,typename z>
struct SomeTemplateClass {
 typedef x myType;
};

then...

SomeTemplateClass<LongVariableNames,ILikePie,AndCheese> cheese;
cheese.myType i;

So i will have the type LongVariableNames .

I know it's probably bad practice to do stuff like this, but I just want to know. What's the simplest way to do something like this?

I mean, it should be possible to resolve this at compile time easily, because of the strong static typing and such. It would be useful to have a typeof() thing just like sizeof() .

Answer 1

Typically it goes like this:

typedef SomeTemplateClass<LongVariableNames,ILikePie,AndCheese> foodType;

foodType cheese;

foodType::myType i;

In C++11 you could also use decltype(cheese)::myType , but that's very ugly.
