Question

Answer 1

Use Attributes.i

In the SWIG Lib folder is a file called "attributes.i" which is not discussed in the documentation but that contains inline documentation.

All you have to do is add the following line to your interface file.

%include 

You then receive a number of macros (such as %attribute) for defining attributes from existing methods.

An excerpt from the documentation in the attributes.i file:

The following macros convert a pair of set/get methods into a "native" attribute. Use %attribute when you have a pair of get/set methods to a primitive type like in:

  %attribute(A, int, a, get_a, set_a);

  struct A
  {
    int get_a() const;
    void set_a(int aa);
  };
