Examples of org.osgi.framework.ServiceRegistration

org.osgi.framework.ServiceRegistration
A registered service.
The Framework returns a {@code ServiceRegistration} object when a{@code BundleContext.registerService} method invocation is successful. The{@code ServiceRegistration} object is for the private use of the registeringbundle and should not be shared with other bundles.
The {@code ServiceRegistration} object may be used to update the propertiesof the service or to unregister the service. @param < S> Type of Service. @see BundleContext#registerService(String[],Object,Dictionary) @ThreadSafe @author $Id: 0bc5bfa68ae7cb4a409c066585d3ab4077d80eeb $
