Examples of org.apache.felix.ipojo.ServiceContext

org.apache.felix.ipojo.ServiceContext
A service context is the facade of a service registry. It gives the access to a service broker. All service interactions should use a service context to garanty the service isolation. This class is a subset of {@link BundleContext} methods.(methods implying interactions with the service registry). So, refer to this class for further information. @see BundleContext @author Felix Project Team
