| 23 | * <code>ConfigurationListener</code>. |
| 24 | * |
| 25 | * <p> |
| 26 | * <code>ConfigurationListener</code> objects are registered with the |
| 27 | * Framework service registry and are notified with a |
| 28 | * <code>ConfigurationEvent</code> object when an event is fired. |
| 29 | * <p> |
| 30 | * <code>ConfigurationListener</code> objects can inspect the received |
| 31 | * <code>ConfigurationEvent</code> object to determine its type, the pid of |
| 32 | * the <code>Configuration</code> object with which it is associated, and the |
| 33 | * Configuration Admin service that fired the event. |

| 35 | * <p> |
| 36 | * Security Considerations. Bundles wishing to monitor configuration events will |
| 37 | * require <code>ServicePermission[ConfigurationListener,REGISTER]</code> to |
| 38 | * register a <code>ConfigurationListener</code> service. |
