/*
* This template wrapper is used to handle C++ objects that are passed or
* returned by value. This is necessary to handle objects that define
* no default-constructor (making it difficult for SWIG to properly declare
* local variables).
*
* The wrapper is used as follows. First consider a function like this:
*
* Vector cross_product(Vector a, Vector b)
*
* Now, if Vector is defined as a C++ class with no default constructor,
* code is generated as follows:
*
* Vector *wrap_cross_product(Vector *inarg1, Vector *inarg2) {
* SwigValueWrapper<Vector> arg1;
* SwigValueWrapper<Vector> arg2;
* SwigValueWrapper<Vector> result;
*
* arg1 = *inarg1;
* arg2 = *inarg2;
* ...
* result = cross_product(arg1,arg2);
* ...
* return new Vector(result);
* }
*
* In the wrappers, the template SwigValueWrapper simply provides a thin
* layer around a Vector *. However, it does this in a way that allows
* the object to be bound after the variable declaration (which is not possible
* with the bare object when it lacks a default constructor).
*
* An observant reader will notice that the code after the variable declarations
* is *identical* to the code used for classes that do define default constructors.
* Thus, this neat trick allows us to fix this special case without having to
* make massive changes to typemaps and other parts of the SWIG code generator.
*
* Note: this code is not included when SWIG runs in C-mode, when classes
* define default constructors, or when pointers and references are used.
* SWIG tries to avoid doing this except in very special circumstances.
*
* Note: This solution suffers from making a large number of copies
* of the underlying object. However, this is needed in the interest of
* safety and in order to cover all of the possible ways in which a value
* might be assigned. For example:
*
* arg1 = *inarg1; // Assignment from a pointer
* arg1 = Vector(1,2,3); // Assignment from a value
*
* This wrapping technique was suggested by William Fulton and is henceforth
* known as the "Fulton Transform" :-).

This macro performs constant aggregation. Basically the idea of
constant aggregation is that you can group a collection of constants
together. For example, suppose you have some code like this:
#define UP 1
#define DOWN 2
#define LEFT 3
#define RIGHT 4
Now, suppose you had a function like this:
int move(int direction)
In this case, you might want to restrict the direction argument to one of the supplied
constant names. To do this, you could write some typemap code by hand. Alternatively,
you can use the %aggregate_check macro defined here to create a simple check function
for you. Here is an example:
%aggregate_check(int, check_direction, UP, DOWN, LEFT, RIGHT);
Now, using a typemap
%typemap(check) int direction {
if (!check_direction($1)) SWIG_exception(SWIG_ValueError,"Bad direction.");
}
or a contract (better)
%contract move(int x) {
require:
check_direction(x);
}
