java.lang.Objectorg.eclipse.gemini.blueprint.extender.support.ConditionalApplicationContextCreator
public class ConditionalApplicationContextCreator
Useful OsgiApplicationContextCreator
implementation that dictates
whether the default application context used by the Spring-DM extender should
be created (or not) based on a boolean
value. This allows
clients to handle only the bundleContext filtering while being decoupled from
the context creation process:
ConditionalApplicationContextCreator creator = new ConditionalApplicationContextCreator(); creator.setFilter(new ConditionalApplicationContextCreator.BundleContextFilter() { // filter bundles with no copyright public boolean matches(BundleContext bundleContext) { return bundleContext.getBundle().getHeaders().get(Constants.BUNDLE_COPYRIGHT) != null) } } creator.createApplicationContext(bundleContext);
