CompositeImpl

public CompositeImpl(BundleData bundledata,
             Framework framework)
              throws BundleException

Throws:

BundleException

Method Detail

findCompanionFramework

protected Framework findCompanionFramework(Framework thisFramework,
                               BundleData thisData)
                                    throws BundleException

Specified by:

findCompanionFramework in class CompositeBase

Throws:

BundleException

getCompositeFramework

public Framework getCompositeFramework()

Description copied from interface: CompositeBundle

Returns the child framework associated with this composite bundle.

Specified by:

getCompositeFramework in interface CompositeBundle

Returns:

the child framework.

getSurrogateBundle

public SurrogateBundle getSurrogateBundle()

Description copied from interface: CompositeBundle

Returns the surrogate bundle associated with this composite bundle. The surrogate bundle is installed in the child framework.

Specified by:

getSurrogateBundle in interface CompositeBundle

Returns:

the surrogate bundle.

getCompanionBundle

protected Bundle getCompanionBundle()

Specified by:

getCompanionBundle in class CompositeBase

update

public void update(Map compositeManifest)
            throws BundleException

Description copied from interface: CompositeBundle

Updates this composite bundle with the specified manifest.

Similar to normal bundle updates, the packages exported by a composite or surrogate bundle can not change as a result of calling update: the previous package exports must be available to other consuming bundles (in either the parent or child framework) until the PackageAdmin.refreshPackages method has been called to refresh the composite, or the parent Framework is re-launched.

Specified by:

update in interface CompositeBundle

Parameters:

compositeManifest - the new composite manifest.

Throws:

BundleException - If the update fails.

CompositeBundleFactory.installCompositeBundle(Map, String, Map)

uninstall

public void uninstall()
               throws BundleException

Description copied from class: AbstractBundle

Uninstall this bundle.

This method removes all traces of the bundle, including any data in the persistent storage area provided for the bundle by the framework.

The following steps are followed to uninstall a bundle:

1. If the bundle is Bundle.UNINSTALLEDthen an IllegalStateException is thrown.
2. If the bundle is Bundle.ACTIVEor Bundle.STARTING, the bundle is stopped as described in the AbstractBundle.stop()method. If AbstractBundle.stop() throws an exception, a FrameworkEventof type FrameworkEvent.ERRORis broadcast containing the exception.
3. A BundleEventof type BundleEvent.UNINSTALLEDis broadcast.
4. The state of the bundle is set to Bundle.UNINSTALLED.
5. The bundle and the persistent storage area provided for the bundle by the framework, if any, is removed.

Preconditions

• getState() not in {Bundle.UNINSTALLED}.

Postconditons, no exceptions thrown

• getState() in {Bundle.UNINSTALLED}.
• The bundle has been uninstalled.

Postconditions, when an exception is thrown

• getState() not in {Bundle.UNINSTALLED}.
• The Bundle has not been uninstalled.

Specified by:

Overrides:

Throws:
