-/**
- * A {@link DOMService} providing access to the conceptual data tree. Interactions
- * with the data tree are split into data producers and consumers (listeners). Each
- * of them operate on a set of subtrees, which need to be declared at instantiation time.
- *
- * <p>
- * Returned instances are not thread-safe and expected to be used by a single thread
- * at a time. Furthermore, producers may not be accessed from consumer callbacks
- * unless they were specified when the listener is registered.
- *
- * <p>
- * The service maintains a loop-free topology of producers and consumers. What this means
- * is that a consumer is not allowed to access a producer, which affects any of the
- * subtrees it is subscribed to. This restriction is in place to ensure the system does
- * not go into a feedback loop, where it is impossible to block either a producer or
- * a consumer without accumulating excess work in the backlog stemming from its previous
- * activity.
- *
- * @deprecated Use {@link org.opendaylight.mdsal.dom.api.DOMDataTreeService} instead.

- * is free to merge the changes, so that a smaller number of them will be reported,
- * possibly hiding some data transitions (like flaps).

- * <p>
- * If the listener wants to write into any producer, that producer has to be mentioned

- * an error. Any producers mentioned must be idle, e.g. they may not have an open
- * transaction at the time this method is invoked.

- * @throws IllegalArgumentException if subtrees is empty or the listener is already bound
- * @throws DOMDataTreeLoopException if the registration of the listener to the specified
