* COMMENTS:
7
* This class is used to tell swig that a function can accept any object
8
* without raising a TypeError exception. The result is a pointer to the
9
* desired type if an object of that type was actually passed in, or null
10
* otherwise.
11
*
12
* Use this class as follows:
13
*
14
* bool isNode(HOM_PtrOrNull<HOM_Node> node)
15
* {
16
* return (node.myPointer != NULL);
17
* }
