  org.knopflerfish.framework.ExportedPackageImpl

All Implemented Interfaces:

ExportedPackage

public class ExportedPackageImpl
extends java.lang.Object
implements ExportedPackage

An exported package. Instances implementing this interface are created by the PackageAdmin service.

Note that the information about an exported package provided by this class is valid only until the next time PackageAdmin.refreshPackages() is called. If an ExportedPackage becomes stale (that is, the package it references has been updated or removed as a result of calling PackageAdmin.refreshPackages()), its getName() and getSpecificationVersion() continue to return their old values, isRemovalPending() returns true, and getExportingBundle() and getImportingBundles() return null.
