Interface BundleDependencyService

public interface BundleDependencyService

The BundleDependencyService declares an API that allows the dependencies between installed bundles to be queried. The interface supports adding and removing an object as a BundleDependencyListener.

The interface also provides a way for bundles to communicate that they should be considered uninstallable, meaning that they wish to be automatically uninstalled when their last dependent bundle is uninstalled.
