| 60 | * The <code>ConfigurationManager</code> is the central class in this |
| 61 | * implementation of the Configuration Admin Service Specification. As such it |
| 62 | * has the following tasks: |
| 63 | * <ul> |
| 64 | * <li>It is a <code>BundleActivator</code> which is called when the bundle |
| 65 | * is started and stopped. |
| 66 | * <li>It is a <code>BundleListener</code> which gets informed when the |
| 67 | * states of bundles change. Mostly this is needed to unbind any bound |
| 68 | * configuration in case a bundle is uninstalled. |
| 69 | * <li>It is a <code>ServiceListener</code> which gets informed when |
| 70 | * <code>ManagedService</code> and <code>ManagedServiceFactory</code> |
| 71 | * services are registered and unregistered. This is used to provide |
| 72 | * configuration to these services. As a service listener it also listens for |
| 73 | * {@link PersistenceManager} instances being registered to support different |
| 74 | * configuration persistence layers. |
| 75 | * <li>A {@link ConfigurationAdminFactory} instance is registered as the |
| 76 | * <code>ConfigurationAdmin</code> service. |
| 77 | * <li>A {@link FilePersistenceManager} instance is registered as a default |
| 78 | * {@link PersistenceManager}. |
| 79 | * <li>Last but not least this instance manages all tasks laid out in the |
| 80 | * specification such as maintaining configuration, taking care of configuration |
| 81 | * events, etc. |
| 82 | * </ul> |
| 83 | * <p> |
| 84 | * The default {@link FilePersistenceManager} is configured with a configuration |
| 85 | * location taken from the <code>felix.cm.dir</code> framework property. If |
| 86 | * this property is not set the <code>config</code> directory in the current |
| 87 | * working directory as specified in the <code>user.dir</code> system property |
| 88 | * is used. |
