接口 RequiredBundle

  • public interface RequiredBundle
    已过时。
    The PackageAdmin service has been replaced by the org.osgi.framework.wiring package.
    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 RequiredBundle object becomes stale if an exported package of the bundle it references has been updated or removed as a result of calling PackageAdmin.refreshPackages()). If this object becomes stale, its getSymbolicName() and getVersion() methods continue to return their original values, isRemovalPending() returns true, and getBundle() and getRequiringBundles() return null.
