+
+ %aggregate_check(int, check_direction, UP, DOWN, LEFT, RIGHT);
+
+ Now, using a typemap

+ %typemap(check) int direction {

+/* The SwigValueWrapper class */
+
+/*
+ * 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
+ *
+ * The class offers a strong guarantee of exception safety.
+ * With regards to the implementation, the private SwigMovePointer nested class is
