-/**\r
- * Binding-aware core of the SAL layer responsible for wiring the SAL consumers.\r
- * \r
- * The responsibility of the broker is to maintain registration of SAL\r
- * functionality {@link Consumer}s and {@link Provider}s, store provider and\r
- * consumer specific context and functionality registration via\r
- * {@link ConsumerSession} and provide access to infrastructure services, which\r
- * removes direct dependencies between providers and consumers.\r
- * \r
- * The Binding-aware broker is also responsible for translation from Java\r
- * classes modeling the functionality and data to binding-indpenedent form which\r
- * is used in SAL Core.\r
- * \r
- * \r
- * <h3>Infrastructure services</h3> Some examples of infrastructure services:\r
- * \r
- * <ul>\r
- * <li>YANG Module service - see {@link ConsumerSession#getRpcService(Class)},\r
- * {@link ProviderSession}\r
- * <li>Notification Service - see {@link NotificationService} and\r
- * {@link NotificationProviderService}\r
- * <li>Functionality and Data model\r
- * <li>Data Store access and modification - see {@link DataBrokerService} and\r
- * {@link DataProviderService}\r
- * </ul>\r
- * \r
- * The services are exposed via session.\r
- * \r
- * <h3>Session-based access</h3>\r
- * \r
- * The providers and consumers needs to register in order to use the\r
- * binding-independent SAL layer and to expose functionality via SAL layer.\r
- * \r
- * For more information about session-based access see {@link ConsumerSession}\r
- * and {@link ProviderSession}\r
