| * OBJECT-ORIENTED FEATURES |
| * |
| * These extensions provide a more object-oriented interface to C++ |
| * classes and structures. The code here is based on extensions |
| * provided by David Fletcher and Gary Holt. |
| * |
| * I have generalized these extensions to make them more general purpose |
| * and to resolve object-ownership problems. |
| * |
| * The approach here is very similar to the Python module : |
| * 1. All of the original methods are placed into a single |
| * package like before except that a 'c' is appended to the |
| * package name. |
| * |
| * 2. All methods and function calls are wrapped with a new |
| * perl function. While possibly inefficient this allows |
| * us to catch complex function arguments (which are hard to |
| * track otherwise). |
| * |
| * 3. Classes are represented as tied-hashes in a manner similar |
| * to Gary Holt's extension. This allows us to access |
| * member data. |
| * |
| * 4. Stand-alone (global) C functions are modified to take |
| * tied hashes as arguments for complex datatypes (if |
| * appropriate). |
| * |
| * 5. Global variables involving a class/struct is encapsulated |
| * in a tied hash. |
