| * Start here! This is the normal entry point into the JAM subsystem. |
| * JamServiceFactory is a singleton factory which can create a new |
| * JamServiceParams and JServices. Here is a code sample that demonstrates |
| * how to use JamServiceFactory. |
| * |
| * <pre> |
| * // Get the factory singleton |
| * JamServiceFactory factory = JamServiceFactory.getInstance(); |
| * |
| * // Use the factory to create an object that we can use to specify what |
| * // java types we want to view |
| * JamServiceParams params = factory.createServiceParams(); |
| * |
| * // Include the classes under mypackage |
| * params.includeSources(new File("c:/myproject/src","mypackage/*.java")); |
| * |
| * // Create a JamService, which will contain JClasses for the classes found in mypackage |
| * JamService service = factory.createService(params); |
| * </pre> |
