Typedef of unique_ptr List

Question

I'd like to make a typedef for std::list<std::unique_ptr<>>, so I could type PtrList<A> and it would be replaced by std::list<std::unique_ptr<A>>.

I know the way to do that with #define:

#define PtrList(x) std::list<std::unique_ptr<x>>

But I think typedef would be proper. However I don't know how to realize that. Could someone tell me how to typedef this ?

Answer 1

First, try not to use #define to generate code. Except for conditional compilation, #define should be avoided.

A correct type alias:

template<class T> using PtrList = std::list<std::unique_ptr<T>>;

Example use:

PtrList<int> intPtrList;
