Examples of IExtensionTracker

org.eclipse.core.runtime.dynamichelpers.IExtensionTracker
An extension tracker keeps associations between extensions and their derived objects on an extension basis. All extensions being added in a tracker will automatically be removed when the extension is uninstalled from the registry. Users interested in extension removal can register a handler that will let them know when an object is being removed.
This interface can be used without OSGi running.
This interface is not intended to be implemented by clients.
@since 3.1
