/* -----------------------------------------------------------------------------
* std_unique_ptr.i
*
* SWIG library file for handling std::unique_ptr.
*
* Returning a std::unique_ptr from a wrapped function:
* Memory ownership is passed (moved) from the std::unique_ptr in the C++ layer
* to the proxy class when returning a std::unique_ptr by value from a function.
* Memory ownership is not moved when returning by any sort of reference.
*
* Passing a std::unique_ptr as a parameter to a wrapped function:
* Memory ownership is passed from the proxy class to the std::unique_ptr in the
* C++ layer when passed as a parameter by value, rvalue reference or non-const
* lvalue reference. Memory ownership is not transferred when passing by const
* lvalue reference.
