| * {@link ExecutableAdapterFactory} for it so that the classes in that model |
| * can be adapted, you need to hook that factory into this one so that later |
| * when an attempt is made to adapt a class from that model is made the |
| * associated factory will be found. You can do that by adding the line: |
| * <code> |
| * ExecutableAdapterFactory.INSTANCE.addAdapterFactory(this); |
| * </code> |
| * to the default constructor of the new factory after the super call. |
| * You're not done however, you also have to "force" an instance of the |
| * class to be created so that the constructor is run. This is typically |
| * achieved by allocating an instance in the method |
| * {@link Activator#start(org.osgi.framework.BundleContext)}of the plug-in |
| * that defines the factory. |
