      • installBundle

        public java.util.List<org.osgi.framework.Bundle> installBundle​(java.lang.String bundleLocation)
        Description copied from interface: com.yahoo.jdisc.application.OsgiFramework

        Installs a bundle from the specified location. The specified location identifier will be used as the identity of the bundle. If a bundle containing the same location identifier is already installed, the Bundle object for that bundle is returned. All bundles listed in the OsgiHeader.PREINSTALL_BUNDLE manifest header are also installed. The bundle at index 0 of the returned list matches the bundleLocation argument.

        NOTE: When this method installs more than one bundle, AND one of those bundles throw an exception during installation, the bundles installed prior to throwing the exception will remain installed. To enable the caller to recover from such a situation, this method wraps any thrown exception within a BundleInstallationException that contains the list of successfully installed bundles.

        It would be preferable if this method was exception-safe (that it would roll-back all installed bundles in the case of an exception), but that can not be implemented thread-safely since an Application may choose to install bundles concurrently through any available BundleContext.

        Specified by:
        installBundle in interface com.yahoo.jdisc.application.OsgiFramework
        Parameters:
        bundleLocation - the location identifier of the bundle to install
        Returns:
        the list of Bundle objects installed, the object at index 0 matches the given location
      • startBundles

        public void startBundles​(java.util.List<org.osgi.framework.Bundle> bundles,
                                 boolean privileged)
        Description copied from interface: com.yahoo.jdisc.application.OsgiFramework
        Starts the given Bundles. The parameter privileged tells the framework whether or not privileges are available, and is checked against the OsgiHeader.PRIVILEGED_ACTIVATOR header of each Bundle being started. Any bundle that is a fragment is silently ignored.
        Specified by:
        startBundles in interface com.yahoo.jdisc.application.OsgiFramework
        Parameters:
        bundles - the bundles to start
        privileged - whether or not privileges are available
      • refreshPackages

        public void refreshPackages()
        Description copied from interface: com.yahoo.jdisc.application.OsgiFramework
        Synchronously refresh all bundles currently loaded. Once this method returns, the class loaders of all bundles will reflect on the current set of loaded bundles. NOTE: This method is no longer used by the Jdisc container framework, but kept for completeness.
        Specified by:
        refreshPackages in interface com.yahoo.jdisc.application.OsgiFramework
      • bundleContext

        public org.osgi.framework.BundleContext bundleContext()
        Description copied from interface: com.yahoo.jdisc.application.OsgiFramework
        Returns the BundleContext of this framework's system bundle. The returned BundleContext can be used by the caller to act on behalf of this bundle. This method may return null if it has no valid BundleContext.
        Specified by:
        bundleContext in interface com.yahoo.jdisc.application.OsgiFramework
        Returns:
        a BundleContext for the system bundle, or null
      • bundles

        public java.util.List<org.osgi.framework.Bundle> bundles()
        Description copied from interface: com.yahoo.jdisc.application.OsgiFramework
        Returns an iterable collection of all installed bundles. This method returns a list of all bundles installed in the OSGi environment at the time of the call to this method. However, since the OsgiFramework is a very dynamic environment, bundles can be installed or uninstalled at anytime.
        Specified by:
        bundles in interface com.yahoo.jdisc.application.OsgiFramework
        Returns:
        an iterable collection of Bundle objects, one object per installed bundle
      • getBundles

        public java.util.List<org.osgi.framework.Bundle> getBundles​(org.osgi.framework.Bundle requestingBundle)
        Description copied from interface: com.yahoo.jdisc.application.OsgiFramework
        Returns all installed bundles that are visible to the requesting bundle. Bundle visibility is controlled via implementations of FindHook;
        Specified by:
        getBundles in interface com.yahoo.jdisc.application.OsgiFramework
      • allowDuplicateBundles

        public void allowDuplicateBundles​(java.util.Collection<org.osgi.framework.Bundle> bundles)
        Description copied from interface: com.yahoo.jdisc.application.OsgiFramework
        Allows this framework to install duplicates of the given collection of bundles. Duplicate detection is handled by the BundleCollisionHook.
        Specified by:
        allowDuplicateBundles in interface com.yahoo.jdisc.application.OsgiFramework
        Parameters:
        bundles - The bundles to allow duplicates of
      • start

        public void start()
        Description copied from interface: com.yahoo.jdisc.application.OsgiFramework
        This method starts the framework instance. Before this method is called, any call to OsgiFramework.installBundle(String) or OsgiFramework.bundles() will generate a NullPointerException.
        Specified by:
        start in interface com.yahoo.jdisc.application.OsgiFramework
      • stop

        public void stop()
        Description copied from interface: com.yahoo.jdisc.application.OsgiFramework
        Synchronously shut down the framework. It must be called at the end of a session to shutdown all active bundles.
        Specified by:
        stop in interface com.yahoo.jdisc.application.OsgiFramework
