/// Transforms the deprecated `std::auto_ptr` into the C++11 `std::unique_ptr`.
|
|
///
|
|
/// Note that both the `std::auto_ptr` type and the transfer of ownership are
|
|
/// transformed. `std::auto_ptr` provides two ways to transfer the ownership,
|
|
/// the copy-constructor and the assignment operator. Unlike most classes these
|
|
/// operations do not 'copy' the resource but they 'steal' it.
|
|
/// `std::unique_ptr` uses move semantics instead, which makes the intent of
|
|
/// transferring the resource explicit. This difference between the two smart
|
|
/// pointers requeres to wrap the copy-ctor and assign-operator with
|
|
/// `std::move()`.
|
|
///
|
|
/// For example, given:
|
|
///
|
|
/// \code
|
|
/// std::auto_ptr<int> i, j;
|
|
/// i = j;
|
|
/// \endcode

///
|
|
/// This code is transformed to:
|
|
///
|
|
/// \code
|
|
/// std::unique_ptr<in> i, j;
|
|
/// i = std::move(j);
