BundleWatcher (Apache Karaf :: Main 2.3.0.redhat-611454 API)

All Known Implementing Classes:

StatsManager
```
public interface BundleWatcher
```
Watches bundle lifecyle processes. This interface is different than that of a BundleLisener because it gets notified before and after all lifecycle changes. A bundle watcher acts as the main entry point for logging bundle activity.
Note that a bundle watcher is always notified of when a lifecycle processes has ended even in cases where the lifecycle process may have failed. For example, if activating a bundle fails the END_ACTIVATION flag will still be sent to the bundle watcher to notify them that the activation process has ended.

Clients may implement this interface.

3.1
