bundleChanged

public void bundleChanged(org.osgi.framework.BundleEvent event)

Specified by:

bundleChanged in interface org.osgi.framework.BundleListener

Overrides:

bundleChanged in class AbstractExtender

load

private static java.util.concurrent.ConcurrentMap<java.lang.Long,java.util.List<ComponentMetadata>> load(org.osgi.framework.BundleContext context,
                                                                                                               ScrLogger logger,

private static void store(java.util.Map<java.lang.Long,java.util.List<ComponentMetadata>> componentsMap,
                          org.osgi.framework.BundleContext context,
                          ScrLogger logger,

Throws:

java.lang.Exception

doCreateExtension

protected Activator.ScrExtension doCreateExtension(org.osgi.framework.Bundle bundle)
                                            throws java.lang.Exception

Description copied from class: AbstractExtender

Create the extension for the given bundle, or null if the bundle is not to be extended.

Specified by:

doCreateExtension in class AbstractExtender

Parameters:

bundle - the bundle to extend

Returns:

The extension

Throws:

java.lang.Exception - If something goes wrong

loadComponents

private void loadComponents(org.osgi.framework.Bundle bundle)

Loads the components of the given bundle. If the bundle has no Service-Component header, this method has no effect. The fragments of a bundle are not checked for the header (112.4.1).

This method calls the Bundle.getBundleContext() method to find the BundleContext of the bundle. If the context cannot be found, this method does not load components for the bundle.

disposeComponents

private void disposeComponents(org.osgi.framework.Bundle bundle)

Unloads components of the given bundle. If no components have been loaded for the bundle, this method has no effect.

protected void debug(org.osgi.framework.Bundle bundle,
                     java.lang.String msg)

Specified by:

debug in class AbstractExtender

warn

protected void warn(org.osgi.framework.Bundle bundle,
                    java.lang.String msg,
                    java.lang.Throwable t)

Specified by:

warn in class AbstractExtender

setLogger

public void setLogger()
