/* -----------------------------------------------------------------------------
 * cpointer.swg
 *
 * This library file contains macros that can be used to manipulate simple
 * pointer objects.

/* -----------------------------------------------------------------------------
 * %pointer_class(type,name)
 *
 * Places a simple proxy around a simple type like 'int', 'float', or whatever.
 * The proxy provides this interface:
 *
 *       class type {
 *       public:
 *           type();
 *          ~type();
 *           type value();
 *           void assign(type value);
 *       };
 *         
 * Example:
 *
 *    %pointer_class(int, intp);
 *
 *    int add(int *x, int *y) { return *x + *y; }
 *
 * In python (with proxies)
 *
 *    >>> a = intp()
 *    >>> a.assign(10)
 *    >>> a.value()
 *    10
 *    >>> b = intp()
 *    >>> b.assign(20)
 *    >>> print add(a,b)
 *    30
 *
 * As a general rule, this macro should not be used on class/structures that
 * are already defined in the interface.
 * ----------------------------------------------------------------------------- */
