org.osgi.util.tracker.BundleTrackerCustomizer

The {@code BundleTrackerCustomizer} interface allows a {@code BundleTracker}to customize the {@code Bundle}s that are tracked. A {@code BundleTrackerCustomizer} is called when a bundle is being added to a{@code BundleTracker}. The {@code BundleTrackerCustomizer} can then return anobject for the tracked bundle. A {@code BundleTrackerCustomizer} is alsocalled when a tracked bundle is modified or has been removed from a {@code BundleTracker}.

The methods in this interface may be called as the result of a {@code BundleEvent} being received by a {@code BundleTracker}. Since {@code BundleEvent}s are received synchronously by the {@code BundleTracker}, it is highly recommended that implementations of these methods do not alter bundle states while being synchronized on any object.

The {@code BundleTracker} class is thread-safe. It does not call a{@code BundleTrackerCustomizer} while holding any locks.{@code BundleTrackerCustomizer} implementations must also be thread-safe. @param < T> The type of the tracked object. @ThreadSafe @author $Id: 031b2979522768150d23ee70dfe62528432c19f7 $ @since 1.4
