| * Inject classes in a component instance field. |
| * The following injections are currently performed, depending on the type of the |
| * field this annotation is applied on: |
| * <ul> |
| * <li>BundleContext: the bundle context of the bundle |
| * <li>DependencyManager: the dependency manager instance |
| * <li>Component: the component instance of the dependency manager |
| * </ul> |
| * |
| * <h3>Usage Examples</h3> |
| * <blockquote> |
| * |
| * <pre> |
| * @Component |
| * class X implements Z { |
| * @Inject |
| * BundleContext bundleContext; |
| * |
| * @Inject |
| * Component component; |
| * |
| * @Inject |
| * DependencyManager manager; |
| * |
| * OtherService otherService; |
| * |
| * @Init |
| * void init() { |
| * System.out.println("Bundle Context: " + bundleContext); |
| * System.out.println("Manager: " + manager); |
| * |
| * // Use DM API for defining an extra service dependency |
| * componnent.add(manager.createServiceDependency() |
| * .setService(OtherService.class) |
| * .setRequired(true) |
| * .setInstanceBound(true)); |
| * } |
| * |
| * @Start |
| * void start() { |
| * System.out.println("OtherService: " + otherService); |
| * } |
