| # Migrating from earlier versions |
| |
| DependencyManager 4.0 has some API changes that need to be taken into account when migrating from DependencyManager 3. |
| |
| * A dependency can no longer be shared accross components. |
| * You no longer have to call setInstanceBound() when adding a dependency from within the init() method of a component. Therefore the setInstanceBound() method has been removed from all Dependency interfaces. |
| * in the Dependency interface, the following method have been removed: isInstanceBound, invokeAdded, invokeRemoved, createCopy. |
| * In the Component interface, the "Object Component.getService()" method has been replaced by the "<T> T getInstance()" method. |
| * In the Component interface, the "void addStateListener(ComponentStateListener listener) method" has been replaced by the "add(ComponentStateListener listener)" method. |
| * In the Component interface, the "start", "stop", "getDependencies" methods have been removed. |
| * In the Component interface and in the DependencyManager class, the createTemporalServiceDependency() method is now taking a timeout parameter: createTemporalServiceDependency(long timeout). |
| * The ComponentStateListener interface has changed: it is now providing a single "changed(Component c, ComponentState state)" method. |
| * The DependencyManager 4 Shell commands are no longer available for framework specific shell implementations, and support the gogo shell only. |
| * The TemporalServiceDependency interface has been removed. |
