Examples of BundleTracker

org.apache.axis2.osgi.deployment.tracker.BundleTracker
BundleTracker listen to bundle events and class the registered Registry objects to deal with them. One be able to add Registry objects to BundleTracker and remove them as necessary. When open() is called BundleTracker will open the tracking and when close() is called close the tracking.
org.apache.camel.impl.osgi.tracker.BundleTracker
The BundleTracker class simplifies tracking bundles much like the ServiceTracker simplifies tracking services.
A BundleTracker is constructed with state criteria and a BundleTrackerCustomizer object. A BundleTracker can use the BundleTrackerCustomizer to select which bundles are tracked and to create a customized object to be tracked with the bundle. The BundleTracker can then be opened to begin tracking all bundles whose state matches the specified state criteria.
The getBundles method can be called to get the Bundle objects of the bundles being tracked. The getObject method can be called to get the customized object for a tracked bundle.
The BundleTracker class is thread-safe. It does not call a BundleTrackerCustomizer while holding any locks. BundleTrackerCustomizer implementations must also be thread-safe. @ThreadSafe @version @since 1.4
