getServiceback to summary
public S getService(Bundle bundle, ServiceRegistration<S> registration)

Implements org.osgi.framework.ServiceFactory.getService.

Doc from org.osgi.framework.ServiceFactory.getService.

Returns a service object for a bundle.

The Framework invokes this method the first time the specified bundle requests a service object using the BundleContext#getService(ServiceReference) method. The factory can then return a customized service object for each bundle.

The Framework must check that the returned service object is valid. If the returned service object is null or is not an instanceof all the classes named when the service was registered, a framework event of type FrameworkEvent#ERROR is fired containing a service exception of type ServiceException#FACTORY_ERROR and null is returned to the bundle. If this method throws an exception, a framework event of type FrameworkEvent#ERROR is fired containing a service exception of type ServiceException#FACTORY_EXCEPTION with the thrown exception as the cause and null is returned to the bundle. If this method is recursively called for the specified bundle, a framework event of type FrameworkEvent#ERROR is fired containing a service exception of type ServiceException#FACTORY_RECURSION and null is returned to the bundle.

The Framework caches the valid service object and will return the same service object on any future call to BundleContext#getService(ServiceReference) for the specified bundle. This means the Framework must not allow this method to be concurrently called for the specified bundle.

public void ungetService(Bundle bundle, ServiceRegistration<S> registration, S service)

Implements org.osgi.framework.ServiceFactory.ungetService.

Doc from org.osgi.framework.ServiceFactory.ungetService.

Releases a service object customized for a bundle.

The Framework invokes this method when a service has been released by a bundle. The service object may then be destroyed.

If this method throws an exception, a framework event of type FrameworkEvent#ERROR is fired containing a service exception of type ServiceException#FACTORY_EXCEPTION with the thrown exception as the cause.
