| 35 | * The <code>ConfigurationManager</code> is the central class in this |
| 36 | * implementation of the Configuration Admin Service Specification. As such it |
| 37 | * has the following tasks: |
| 38 | * <ul> |
| 39 | * <li>It is a <code>BundleActivator</code> which is called when the bundle |
| 40 | * is started and stopped. |
| 41 | * <li>It is a <code>BundleListener</code> which gets informed when the |
| 42 | * states of bundles change. Mostly this is needed to unbind any bound |
| 43 | * configuration in case a bundle is uninstalled. |
| 44 | * <li>It is a <code>ServiceListener</code> which gets informed when |
| 45 | * <code>ManagedService</code> and <code>ManagedServiceFactory</code> |
| 46 | * services are registered and unregistered. This is used to provide |
| 47 | * configuration to these services. As a service listener it also listens for |
| 48 | * {@link PersistenceManager} instances being registered to support different |
| 49 | * configuration persistence layers. |
| 50 | * <li>A {@link ConfigurationAdminFactory} instance is registered as the |
| 51 | * <code>ConfigurationAdmin</code> service. |
| 52 | * <li>A {@link FilePersistenceManager} instance is registered as a default |
| 53 | * {@link PersistenceManager}. |
| 54 | * <li>Last but not least this instance manages all tasks laid out in the |
| 55 | * specification such as maintaining configuration, taking care of configuration |
| 56 | * events, etc. |
| 57 | * </ul> |
| 58 | * <p> |
| 59 | * The default {@link FilePersistenceManager} is configured with a configuration |
| 60 | * location taken from the <code>felix.cm.dir</code> framework property. If |
| 61 | * this property is not set the <code>config</code> directory in the current |
| 62 | * working directory as specified in the <code>user.dir</code> system property |
| 63 | * is used. |
