Examples of org.osgi.service.packageadmin.RequiredBundle

org.osgi.service.packageadmin.RequiredBundle
A required bundle. Objects implementing this interface are created by the Package Admin service.
The term required bundle refers to a resolved bundle that has a bundle symbolic name and is not a fragment. That is, a bundle that may be required by other bundles. This bundle may or may not be currently required by other bundles.
The information about a required bundle provided by this object may change. A {@code RequiredBundle} object becomes stale if an exported package ofthe bundle it references has been updated or removed as a result of calling {@code PackageAdmin.refreshPackages()}). If this object becomes stale, its {@code getSymbolicName()} and{@code getVersion()} methods continue to return their original values,{@code isRemovalPending()} returns true, and {@code getBundle()}and {@code getRequiringBundles()} return {@code null}. @since 1.2 @ThreadSafe @noimplement @deprecated The PackageAdmin service has been replaced by theorg.osgi.framework.wiring package. @author $Id: 08ab9c1a6f4a9af2060293d2c2972e4e07e2a238 $
