Class RecursiveBundleTracker

java.lang.Object

org.apache.aries.util.tracker.RecursiveBundleTracker

public final class RecursiveBundleTracker
extends java.lang.Object

This class supports the tracking of composite bundles. It allows clients to ignore any events related to framework bundles, as it will automatically handle these events. In order to use this class clients must create a subclass and implement the methods of the BundleTrackerCustomizer interface. In spite of this, instances of this class MUST NOT be passed as a parameter to any BundleTracker.

The model for using this is that classes should instantiate it and pass it a 'vanilla' bundle tracker.
