Examples of org.osgi.framework.wiring.BundleRevisions

org.osgi.framework.wiring.BundleRevisions
The {@link BundleRevision bundle revisions} of a bundle. When a bundle isinstalled and each time a bundle is updated, a new bundle revision of the bundle is created. For a bundle that has not been uninstalled, the most recent bundle revision is defined to be the current bundle revision. A bundle in the UNINSTALLED state does not have a current revision. An in use bundle revision is associated with an {@link BundleWiring#isInUse() in use}{@link BundleWiring}. The current bundle revision, if there is one, and all in use bundle revisions are returned.
The bundle revisions for a bundle can be obtained by calling {@link Bundle#adapt(Class) bundle.adapt}( {@link BundleRevisions}.class). {@link #getRevisions()} on the bundle. @ThreadSafe @author $Id: 83e7bf03af2150a54af13a319325856e532cefde $
